Fistula. What is it? This term refers to the deformation on the pipe in the form of a hole. The main reason for its appearance is considered to be chiseled corrosion. This is a clear sign that the plumbing structure is worn out and needs to be replaced. However, not always a person can immediately carry out a full range of work to replace the system with a new one. In this case, a partial repair is required to eliminate the fistula. It is worth remembering that such repairs are temporary, they do not eliminate the need to replace worn-out pipes. To carry out the work, you can call the wizard, but you can do them yourself.
Tools and materials
In order to eliminate the fistula, you need to stock up on the following tools and materials:
- Drill;
- Bolt set;
- Special adhesive composition BV-2;
- Metal brush;
- Epoxy adhesive;
- Petrol;
- Tap;
- Acetone;
- Kern;
- Putty knife.
Before removing the fistula, it is necessary to drain the water from the system. For this purpose, it is required to close the stop valve. Then all the taps open.
How to remove a pipe fistula on your own
Fistula. What is it? This term refers to the deformation on the pipe in the form of a hole. Turned corrosion is considered the main cause of its occurrence. This is a sign that the design of the gauge assembly is worn out and needs to be changed. However, not always a person can immediately do a full range of work to replace the system with a new one. In this case, it is required to make selective repairs to eliminate the fistula. It must be remembered that such repair works are temporary, they do not eliminate the need to change pipes that have already worn out. To complete the work, you can call the master, but you can do them on your own.
In order to remove the fistula, it is worth stocking up on the following materials and tools:
- Drill;
- Bolt kit;
- Specialized composition of BV-2 glue;
- Metal brush;
- Epoxy glue;
- Petrol;
- Tap;
- Acetone;
- Kern;
- Putty knife.
Appears due to rust
Before removing the fistula, you need to remove the water from the system. For this purpose, it is required to close the stop valve. Then all the taps open.
How to remove a defect with a bolt
First you need to enlarge the fistula. This is done with a drill. The tap is used to cut elements with a thread. The bolt is screwed into the widened hole. It must be said that these repair works are recommended to be performed only if the pipes are not particularly worn out. If the structure is old, it is unlikely that it will work out to make a good thread on it. This will only increase the defect.
It is acceptable to perform this type of repair work if an elongated fistula appears on the structure. In order to seal it, a bandage with a rubber seal is applied. A seal can be created from rubber gloves, an unnecessary tire from a bicycle, a medical tourniquet, a piece of rubber boots. The size of the seal should be more than the volume of the defect in the pipe. Such a gasket is fixed to the structure with clamps or bolts.
How to seal a hole with an adhesive bandage
To begin with, the pipe is cleaned with a metal brush. Then she gets off with acetone or gasoline. The wait is about 15 minutes. At this time, you can start cutting fiberglass into equal parts. The ideal dimensions of these tapes are in direct proportion to the dimensions of the pipes. The tape is cut correctly if it is possible to wrap the structure with it at least 6 times. The width of the segment should be three times the diameter of the structure. BV-2 glue composition is applied to the edges of fiberglass segments.Then, on one side of the segment, an epoxy glue is smeared with a spatula. It should saturate the cut perfectly. For this, during the application of the glue, the spatula must be perfectly pressed against the surface of the tape. Then it is wrapped around the structure. The middle of the segment should fall on the territory where the fistula appeared. The bandage is pulled together with a metal tape. The structure is left for a day. If it is located in an unheated room, it will take at least 4 days to wait until the system is ready for operation.
We eliminate the defect by "cold welding"
The defect should be enlarged with a drill. Then the structure is cleaned of dirt, trimmed with acetone. Wait until the structure is dry, and then apply the "cold welding" compound to it. It dries for 10 minutes.
Important: If you use "cold welding" or epoxy glue for repair work, you should wear rubber gloves. The glue should not come into contact with the integument of the skin. If it does get on the skin cover, it must be removed without delay with cotton wool soaked in acetone, and then perfectly wash the area where the glue turned out to be with warm water and soap.
Summing up, it must be stated that the listed methods, which allow sealing a hole in pipes, give only a short-term result. We advise you to replace the meter unit with a new one. People who do not allow the structure to wear out do not even know that this is a fistula.

How to seal a hole with an adhesive bandage
To begin with, the pipe is cleaned with a metal brush. Then it is processed with acetone or gasoline. The wait is about 15 minutes. At this time, you can start cutting fiberglass into equal parts. The optimal dimensions of such belts are in direct proportion to the size of the pipes. The tape is cut correctly if it is possible to wrap the structure with it at least six times. The width of the segment should be three times the diameter of the structure. BV-2 adhesive is applied to the edges of the fiberglass segments. Then, on one of the sides of the segment, an epoxy adhesive is spread using a spatula. It should saturate the cut well. For this, during the application of the glue, the spatula must be well pressed against the surface of the tape. Then it is wrapped around the structure. The middle of the segment should fall on the area where the fistula formed. The bandage is pulled together by means of a metal tape. The structure is left for a day. If it is located in a cold room, it will take at least 4 days to wait until the system is operational.
We eliminate the defect by "cold welding"
The defect should be expanded with a drill. Then the structure is cleaned of contamination, treated with acetone. Wait until the structure is dry, and then apply the "cold welding" compound to it. It dries up within ten minutes.
Caution: Wear rubber gloves if you use cold weld or epoxy for repair work. The glue should not come into contact with the skin. If it does get on the skin, it should be immediately removed with cotton wool soaked in acetone, and then the area where the glue turned out to be washed well with warm water and soap.
In conclusion, we can say that the listed methods, which make it possible to seal the hole in the pipes, give only a temporary result. We recommend that you replace the water supply with a new one. People who do not allow the structure to wear out do not even know that this is a fistula.
The term "pipe fistula" - denotes deformation changes in the form of a through hole in the pipeline. The main reason for the formation of this phenomenon on pipe-rolling is considered to be pitting corrosion.
It is a clear signal that the pipeline needs urgent replacement. It is not always possible to perform a full range of pipe repairs with replacement, therefore, it is performed only partially.
At the same time, we must not forget that such events are temporary, and the replacement of areas that have become unusable cannot be avoided anyway. You can use the help of professional craftsmen, or you can repair everything with your own hands.
For embedding, you need to prepare the following tools:
- Drill.
- Bolts (set).
- Brush for cleaning metal products.
- Bonding agent BV-2, and epoxy bonding type.
- Acetone and Gasoline.
- Ketn.
- Putty knife.
Before closing the fistula in the pipe, water is drained from the network. To do this, you need to close the stop valve and open each valve. The system must be free of residual water.
After that, the cleaned area must be degreased with acetone. For the same purpose, you can use gasoline. When sealing, this step is very important.
When applying a bandage to a workpiece with an uneven surface, it is impossible to obtain the most tight joint, and all the sealing measures will have to be repeated anew.
On a well-cleaned surface of the product, the amount of deformation can be accurately determined. And, guided by the information received, they determine the way to further eliminate the deficiency. Fistulas by the form of education are divided into: point
and
elongated
... Eliminate each of them in different ways.
Flows in the middle of the pipe
It is necessary to inspect everything and identify the place of damage. What if the hole is small and water is flowing, but there is no way to call the plumber? You can use Titanium White Automotive Putty to seal the hole.
This repair method will extend the life of the pipe for several years, but only if it does not supply water under high pressure.
If it flows well, then a layer of rubber is applied to the place of the gap, the so-called bandage, which should be larger in size than the hole.
The patch is fixed with a soft wire. All of the above items can be purchased at a hardware store.
Do not forget that in this way it can be repaired only for a temporary action (until the arrival of a master who can fix everything qualitatively).
Loose connecting seam
What to do if water flows at the junction of the pipe to the battery, with a tap or in the area of the threaded joint? In this case, the elimination of the problem will be somewhat complicated, since sometimes elements of different diameters are connected.
How to close up in this case? You can seal the hole using a piece of thin rubber, which must be clamped with a special metal clamp.
Such a solution cannot be a 100% solution to the problem. The junction will have to be disassembled and thoroughly welded or glued.
Final repairs can only be carried out with a complete shutdown of the heating system and water drain. If in a private house this process can be done independently, then in an apartment it is recommended to entrust this work to a specialist.
If the house has autonomous heating, the owner must constantly have new couplings and spare connecting elements on hand in order to quickly close the hole in the event of an accident.
Leaking between battery sections - what to do?
A small hole from which water flows can be repaired using an ordinary self-tapping screw that can be found in every household.
Naturally, such a solution will not be enough for a long time, but it will still help to get rid of damage, which can cause even a slight leak.
Second way. It is recommended to wrap the problem area with a dense cloth impregnated with a sealant or an adhesive solution resistant to water (hypoxy glue).
When the fabric is dry, you can connect the battery to the system, but in order to properly repair it, you should still seek help from a plumber.
What to do if the accident is caused by a surge in water pressure? First of all, you should take care of the elimination of the internal problem.
From the use of pipes of excellent cross-sectional dimensions, water hammer may occur, especially in the process of eliminating air pockets.
When is it necessary to repair the heating system?
In any case, overhaul robots of heating systems are carried out on warm spring or summer days before the start of the winter season.
If the apartment has had iron pipes for more than one five years, you need to think about replacing them with reinforced polypropylene samples, without waiting for it to burst.
The latter do not undergo oxidation when interacting with water and withstand water shocks, which makes them more durable than iron ones. Often, when repairing pipes of a heating system, professionals recommend sealing the holes with "cold welding". This material is extremely durable and, after drying, reliably bridges any leaks.
All the above methods of repairing heating pipes are not bad, but they can save only for some time, so in order not to ask yourself the following question: "The heating pipe is leaking, what should I do?" - call a plumber who will be able to correctly and reliably eliminate all malfunctions associated with the operation of the heating system, so that later, with the onset of winter, does not carry out expensive repairs and does not disconnect the whole house from heating.
Features of hot water supply
Fistula in the hot water pipe appears more often than in other places. The place that is most susceptible to this phenomenon is the riser. The first signs of danger in such a system are rusty build-up.
Video: how to fix a leak on a squeegee
Such a fistula in the pipeline can be closed by means of a bolt or a temporary bandage. And in the first and in the second case, it is impossible to act under pressure. The water supply must be shut off, only then can work be done.
A small leak can be repaired under pressure using an adhesive bandage. The edges of fiberglass with applied BF-2 glue are applied to the damaged area (the tape is applied very tightly). At the end, the tape must be pulled together with a metal plate. Such a section will be able to function under pressure only after 24 hours.
Also in this situation, you can seal the leak with "cold welding". It is better not to do such work under pressure. The resulting hole is slightly enlarged with a drill, and the area is degreased.
When everything dries up, a composition is applied to the flowing gap. It should freeze completely. This takes about ten minutes.
Well fistulas
If we consider the sources of water supply in private areas, then wells can be called the most promising. Compared to wells, they contain water of a higher quality. It practically does not need cleaning and additional filtration.
During the operation of the well, the pump and water lifting pipelines vibrate. This leads to a weakening of the joints on the water-lifting lines, and, accordingly, leaks (fistulas) appear. This often results in serious accidents.
In what ways is the work carried out
Repair of fistulas on pipes is carried out by the following methods:
- Bolt use
... In this way, they act when it is necessary to close a small hole. The hole is widened with a drill, and a thread is cut in the prepared hole. A prepared screw or self-tapping screw is screwed into it. It is not recommended to do this in old highways. The old age of used metal can lead to the appearance of a more voluminous hole in the "problem" place. - Rubber bandage
... This method is universal, because it is suitable for all pipe rolling stock and any type of water leak. The bandage is selected depending on the size of the leak.It is advised to put a rubber gasket, and a strip is cut out of it 0.5 cm larger than the bandage, and a centimeter smaller than the circumference of the nozzle. It is installed under it and the structure is placed on the fistula zone. If it is not very large, then during the repair it is allowed not to interrupt the water supply. - Repair with adhesive bandage
... First, you need to prepare a strip of fiberglass, or an ordinary bandage. The size of the tape should be enough to wrap the product six times. This tape is soaked with epoxy glue and wrapped so that the flow is located in the center. At the end, the bandage must be secured with a clamp. This pipe network will be able to function only a day after the repair. - Cold weld sealing
... This option is temporary. It targets small holes. After it, it is better to repair the problem area in one of the more reliable ways. The described method is not long-term due to the fact that the effect of water and high temperature on liquid welding leads to its weakening. For repairs with cold welding, you just need to apply it to the appeared area of water leakage on the product.

What to do
If the water is gushing, it is recommended to change the system or part of it immediately., all attempts to solve the problem by other methods can be only temporary.
If the trickle is small, the leak can be eliminated by plugging the hole, having previously turned off the water supply. After draining the system, it is easier to determine the size of the hole. To do this, clean up the leak with sandpaper, removing a layer of paint and rust.
Before proceeding with the elimination of the problem, it is necessary to degrease the surface with acetone or gasoline.
Note! Cleaning and degreasing is an important stage in the repair, if you neglect this and try to close the hole on an untreated uneven surface, it is difficult to achieve maximum tightness, and after a while the problem will again make itself felt.
By cleaning and degreasing the surface, you can evaluate the nature of the hole and its size, and choose the most correct repair method.

If the hole is small, you don't even need to interrupt the water supply.
Troubleshooting Plastic Products
A fistula on a plastic pipe is closed in two ways: threaded
and
soldering
.
The threading method can only be used for products where threading is possible. A piece of pipe that has become unusable with a fistula is cut off with special scissors.
An insert is prepared from blanks of the required volume. On plastic materials, the thread is cut with a stick. Then, with fittings and couplings, another structure is attached to the pipe network.
Welding on plastic pipe materials begins with cutting off the flowing section. After that, a fitting and a workpiece of the appropriate size are prepared.
A heated plastic pipe soldering iron is used to heat the outer edges of the plastic and the inner edges of the fittings. At the final stage of the repair, the prepared pipe is connected with fittings.
This should be done without delay, since plastic tends to instantly solidify, and it is not possible to remake an incorrectly fastened structure a second time.
Holes in polymer lines
A leak in a plastic pipe happens extremely rarely, it must be eliminated by the following methods:
- If an accident has occurred in the area of the fittings, they are simply tightened. You can additionally use a sealant. It is important not to overdo it so that the polymer does not burst during tightening. Polypropylene couplings will have to be re-soldered using special equipment.
- If a crack has formed in a straight section, it will have to be cut and replaced. Fittings are used for PVC elements. For polypropylene - welding method.
An important condition in the elimination of emergency situations of water supply, heating is the care and competence of the master. If there is no experience in such work, it is better to use the services of a professional plumber.
Repair of copper products
A copper pipe fistula is not uncommon. Copper pipes have been used in construction for a very long time. They are not only suitable for all types of highways, but also have high ductility and resistance to corrosion.
Video
Their service life is not limited, and with ease they will stand the entire period allotted to the house without breakdowns. But, sooner or later, situations arise when these products need to be repaired from the fistula.
For which you need the participation of a specialist. In order not to face the fact of a large fistula, the network should be checked regularly. At the slightest notice of damage, you should immediately take up the elimination.
How to fix a defect with a bolt
First you need to expand the fistula. This is done with a drill. The tap is used to cut threaded elements. The bolt is screwed into the widened hole. It is worth noting that these repairs are recommended to be performed only if the pipes are not badly worn out. If the structure is old, it is unlikely that it will be possible to make high-quality threads on it. This will only increase the defect.
Elimination of the fistula.
Malfunctions in the heating line
Communications do not last forever, and even with the use of high-quality materials, a fistula may form on the heating pipe.
The following reasons become the basis for a heating leak:
- Wear. It is associated with a long period of use of the heating system. Most often, steel products suffer from leaks.
- Violation of the operating conditions of the heating system. This includes surges in temperature and pressure, water hammer.
- Use of goods of questionable quality.
- Poor tightness of the joints.
If a leak appears on the heating pipes, proceed as follows.
Video
It is necessary to prepare several clamps with rubber seals (in this case, the most important thing is not to forget to turn off the water, stop the operation of the heating boiler, disconnect the pumps from the power supply and close the necessary valves and taps
). Repair of pipe-rolling assortment in the heating network depends on their type.
For example, steel pipes with a problem of a joint of a threaded variety will require disassembling the joint, and applying a new layer of winding.
If the destruction has formed on the heating pipe itself, then the problem area will have to be welded using gas or electric welding.
If a copper pipe is leaking, then it must also be welded. But, welding work with copper is rather complicated, therefore, it is better to entrust them to specialists.
If the metal-plastic pipelines of the heating system are leaking, then it will be necessary to replace the entire section where the leak has formed. In this type of pipe rolling, it is most often formed in compressor-type joints.
On plastic heating pipelines, the problem is solved in this way. This is a replacement for an entire site. Soldering of polypropylene is advised to be carried out in accordance with all the norms of this work. Any errors can provoke the fact that the joint collapses after a very short time.

IMPORTANT!
When working with plastic products, it is forbidden to make changes to the wiring diagram.
Where leaks are most common
Most of the leaks are caused by improper installation. The joints of pipes with radiators are considered to be especially weak.
But there is another big point - the wrong choice of material. It is not necessary to use polypropylene pipes intended only for cold tap water for the installation of heating communications.
As a result, when hot water is supplied, they cannot withstand the resulting pressure, as a result of which a leak occurs.
What can you do to rid your heating system of such a situation?
Most often, a leak can form at the joints in the place of the connecting seam or the connection of the pipe to the battery.
Features of metal pipelines
If we are talking about how to weld a fistula in a pipe, which is large in size, then there is only one recommended way out - a complete replacement.
And, if the fistula is small, then here are some options for action. But, these recommendations can only be applied when the metal assortment pipes are leaking.
Video
Option 1
... In this case, the defect is eliminated with a medical bandage and cement for sealing. First, a solution of cement and water is diluted. 15-20 strips are cut from the bandage, 20 cm long. The strips are moistened in the solution and wrapped around the main line. The result is something that looks like a cocoon. A cement solution is applied on top of it. All this should dry for 24 hours, and then the pipe network can be started up.
Option 2.
Pieces of rubber to make repairs. A strip is cut out of the rubber, slightly longer than the circumference of the pipe. The problem area is tightly fitted with this strip, which is then fixed. For reliability, it must be covered with a cement bandage, as described in the previous method.
Option 3
... Bandage and table salt. So small "gaps" between the joints are covered. For this, the place of leak is wrapped with a bandage mixed with salt. Dissolving salt fixes microleakage. But this method cannot be applied to large formations; one should act differently.
Defects in water supply networks
How to close a fistula in a water pipe, people are often interested. Unfortunately, plumbing leaks are very common.
To seal the place of water flow in this case, you can use such devices as a clamp, cold welding or any other folk methods.
The condition of the plumbing system must be checked constantly. If the workpieces have served for a long time, and it is not possible to replace them quickly, then it is necessary to prepare several clamps for a stock in order to make repairs, because water leakage in such products can form at any time.

If streaks of rust appear on the water supply system and paint swells in places on the pipes, then this serves as a signal of the imminent appearance of pitting corrosion.
IMPORTANT!
A fistula in a cold water pipe under a layer of paint is not as dangerous as in an analogue with hot water. If the water from under the removed paint during the repair from the pipe breaks through with a fountain, it can cause serious burns to a person.
Leaking sewer lines
Considering the question of how to eliminate a fistula in a sewer pipe, it should be noted that to cope with this task a little harder
than to repair water leaks at the joints.
At the beginning of the embedding, an assessment of the defect and strength of the workpiece will be required. Small leaks can be eliminated by means of plugs for this type of tube rolling. You can also try the repair method - wrapping with gauze soaked in epoxy resin.
The option with a rubber gasket secured with a clamp will help to temporarily seal the water leak. It and a repair clamp can be purchased at any building materials store. Also, its gasket can be fixed using a wire.
Longitudinal cracks and chips on the branch pipe can be easily repaired with a sealant. To do this, the fistula is slightly enlarged, degreased and dried.
After that, a sealant is applied to the site. Metallic materials in the sewage system from water leaks are sealed with cold welding.
Do-it-yourself leak repair
Water leaks occur at any time, so sealing fistulas in pipes with your own hands is a very important skill.
For very urgent closure of the fistula, a clamp is recommended. It is a metal tie. And you need to apply a clamp in this way:
- The water supply system is blocked.
- The bolts on the clamp are loosened and wrapped around the water leakage area.
- The nuts on the clamp are tightened with an adjustable wrench, while the pipe itself is adhered to with a pipe wrench. Without support, which will entail additional water leaks and repair costs.

Termination methods with the use of a locknut and with the help of a rubber band are also effective. In general, it is not difficult to close up and eliminate a fistula on a pipe.
If you are not confident in your abilities, then it is worth inviting professional masters. And if the filling of the fistula was carried out in one of the temporary ways, then it is worth worrying about how to carry out a full-fledged pipe repair in the near future.
This article will consider how the fistula that appears on the pipe is closed, what methods of termination exist, and detailed instructions for termination are given.
The situation with the appearance of a fistula in a metal riser for heating or water supply occurs quite often, especially in the case of a riser for hot water supply.
The first sign that a fistula has appeared in the pipe and it can "jerk" is the appearance on it in some cases of a red build-up, which is scientifically called pitting corrosion, and among the people - "a pipe in a pipe".
Fistulas appear in pipes both as a result of wear and tear and under the influence of stray currents, but at the moment of appearance of a fistula, the cause fades into the background, and it is much more important to find out how to fix the situation.
A fistula appeared in the pipe - what to do?
If the heating pipe suddenly "whistled", then your further actions must be coordinated with the local management company. After all, leaks in such pipelines are in the area of responsibility of the public utilities. And for one fistula, a second may come, and there it is not far before a serious accident. Therefore, if you see a fistula in the heating pipe, do not hesitate to call the emergency service of your management company. Sealing fistulas in heating pipes is their job. In the meantime, they are getting close to your apartment - substitute a plastic basin under the trickle of water and be patient.
If the hot or cold water supply pipe gushes, then you can correct this situation yourself. Just before fixing the problem, you should shut off the water supply to the leaked section of the domestic water supply system.
To do this, you just need to turn the handle of the central valve located before the hot and / or cold water meter across the pipe.
If the sewage system has leaked, then you should only localize the place of the leak, along the leaks on the pipe body. There is no need to close the sewer - gravity systems let water through themselves only from time to time. Therefore, start repairing the pipe right away.
How to close up a fistula that appears on a pipe - options
It is possible to eliminate the fistula using various technological methods. The specific method is selected based on the size of the problem area. And further in the text we will look at several typical ways to solve this problem.
Repair with a screw bolt or self-tapping screw
For example, relatively small fistulas can be repaired with a conventional screw.
And for this you need to do the following:
- At the very beginning, you clean the problem area from rust and paint.
- Next, you localize the breakthrough and drill out the fistula using a metal drill and a drill for this purpose.
- In the next step, you cut a thread in the hole, replacing the drill with a tap.
- After tapping, you simply screw the screw or bolt into the hole.
However, this instruction for sealing the fistula can be improved if, instead of a drill and a tap, you use a conventional metal self-tapping screw with a feather drill at the end.... Such a hardware product will be screwed into any pipe, reliably plugging the breakthrough site.
Repair with epoxy adhesive
An alternative technique - sealing the fistula with an adhesive bandage - is practiced in case of detection of sufficiently large sections of a pipe break. In this case, you will not be able to plug the fistula, and you will have to apply a simple patch over the hole, glued to the epoxy glue.
Well, the process of gluing the fistula itself is as follows:
- To begin with, you will have to get rid of old paint and rust, not only at the breakout point, but also around the entire circumference of the pipe.
- Next, you should buy a strip of fiberglass, the width of which will be one and a half to two times larger than the diameter of the pipe to be glued. The length of the future band should be equal to 8-10 values of the circumference of the pipe to be glued.
- After purchasing all the components, you simply degrease the pasting site with acetone and impregnate the fiberglass strip with epoxy glue. Moreover, the results of your efforts will depend on the quality of the impregnation.
- After preparing the tape, you simply wrap it around the pipe, pulling it as tightly as possible. Ideally, the turns of the tape should adhere to the pipe without gaps or creases, forming a tight cocoon.
- At the very end, you fix the tape with metal clamps.
Fistula sealing methods
The fistula that appears in the pipe can be closed in several ways, each of which requires preliminary draining of water
from the system by closing the stop valve and opening all taps. Let's consider the main methods of sealing fistulas in more detail.
Sealing with a bolt
Includes the following steps:
- The fistula is widened with a drill.
- With a tap.
- A bolt is screwed into the resulting hole.
Important: this method is not suitable for old pipes, since it is almost impossible to cut into them, attempts to cut usually lead to an increase in the diameter of the leak.
Sealing with a temporary bandage
This method is usually used when the pipe fistula has an elongated elongated shape.
A bandage with rubber gaskets is applied to the fistula, and materials such as:
- Thick rubber glove;
- Old bicycle tire;
- Medical tourniquet;
- The shaft of a rubber boot, etc.
Important: the rubber gasket must be substantially larger than the fistula.
The gasket is fixed to the pipe using special clamps or bolts.
Sealing with adhesive bandage
Using an adhesive bandage, the fistula on the pipe is closed as follows:
- Clean the pipe from dirt with a metal brush, treat its surface with gasoline or acetone and allow it to dry for at least 15 minutes.
- The fiberglass is cut into strips, the dimensions of which depend on the diameter of the pipe so that the length of the tape allows at least 6 layers of winding, and its width exceeds the pipe diameter by at least a third.
- The edges of the tape are treated with BF-2 glue, after which they are covered with epoxy glue on one side of the tape with a spatula.
- Press the spatula firmly so that the tape is saturated with glue.
- Next, the tape is tightly wound on the treated and cleaned surface so that the center of the tape overlaps the damaged area.
- The bandage is pulled together with a metal tape.
- In a day
a repaired pipe can be used.
Important: in the case of a pipe located in a cold room with an air temperature not exceeding 17 °, the pipe should be used only after 4 days.
Repair by "cold welding" method
To temporarily seal the formed fistula, you can also use a special compound called "cold welding":
- The fistula is expanded with a drill.
- The pipe surface is cleaned and degreased with acetone.
- After the pipe has dried, the composition is applied to it and wait for its complete hardening within 10 minutes.
Important: work with epoxy glue and "cold welding" should be done with rubber gloves.
If the glue or composition gets on the skin, wipe it with cotton wool moistened with acetone, and then wash your hands thoroughly with soap and warm water.
Repair using a temporary bandage
This method is used when the fistula in the pipeline has an elongated elongated appearance.
A bandage is applied to the hole using gaskets, which can be made from the following products:
- medical tourniquet;
- thick glove;
- bicycle tire;
- bootleg, etc.
The main thing is that the size of the rubber gasket is much larger than the size of the hole. To fix the bandage on the pipeline, clamps or bolts are used.
Fistula sealing instructions
Such preparation can be useful if a fistula occurs at night - and there is a risk of serious flooding while waiting for the locksmith on duty or the emergency team.
In case of a small fistula, it can be repaired with a standard car clamp:
- A thin tape is cut from a piece of rubber, the width of which is equal to or 3-4 mm more than the width of the clamp. The length of the tape is measured by wrapping around the pipe and cutting off the excess.
- Next, the clamp is opened and put on the pipe.
- Slightly grab the clamp.
- A cut out rubber gasket is inserted under the clamp and carefully brought to the site of the fistula formation.
- Cover the fistula and tighten the clamp with a wrench or screwdriver, depending on the clamp tightening device.
As a temporary measure, when there is a very small fistula, and there is no clamp at hand, the fistula can be closed by simply breaking off and inserting the tip of a match into it.
Important: this method should be used only as a last resort - as a result, when the pipes are very old, the fistula may not close, but only increase in diameter.
And even in the case of successful sealing of the fistula with a match, it should be closed as soon as possible with the help of a clamp.
In case of a more serious fistula, it is also advisable to have a more solid clamp ready (see photo):
- The first step is to turn off and drain the water from the pipes.
- Before installing the clamp, inspect the pipe surface. If it is uneven, it is smoothed with sandpaper to prevent water from flowing through the existing roughness.
- Next, as described, cut out a rubber lining under a more powerful clamp and also install it in the place of the fistula.
As you can see from the article, self-sealing of fistulas in pipes is not particularly difficult, for this you do not need any special skills and tools. In the event that metal risers are installed in the apartment, it is advisable to always have a couple of clamps and rubber gaskets ready for them so that the appearance of a fistula does not catch by surprise.
The most common cause of holes in steel pipelines is pitting corrosion. As a rule, the appearance of fistulas indicates the deterioration of the water supply system. To avoid serious accidents, it is recommended to completely replace the water pipes. If, for some reason, replacing the pipes is not possible, you can carry out temporary repairs with your own hands.
In order to close the fistula in the pipe, you will need:
- drill or core,- tap,- bolts,- glue BF-2,- metal brush,- gasoline or acetone,- putty knife,- epoxy adhesive
Drain the system before starting work. To do this, close the stop valve and then open all the taps.
Bolt repair
Expand the fistula with a drill, tap the thread. Then screw the bolt into the hole. Please note that this repair method is not suitable for old pipes. Most likely, it will not be possible to cut a full thread on the old pipe and the size of the leak will only increase.
Repair with a temporary bandage
This type of fistula repair is usually used if the fistula has an elongated oblong shape. Apply a bandage with rubber seals.A thick rubber glove, an old bicycle tire, a rubber boot flap, or a medical tourniquet can be used as a spacer. The size of the rubber pad should be much larger than the size of the fistula. Fix the gasket to the pipe using bolts or special clamps.
Repair with adhesive bandage
Clean the pipe from dirt with a wire brush. Treat the pipe surface with acetone or gasoline. Let dry for 15 minutes (minimum). ? Cut the fiberglass into tapes. Their dimensions are determined based on the diameter of the pipes. The length of the tape should be at least six layers of winding. And the width should exceed the pipe diameter by more than a third.? Treat the edges of the tape with BF-2 glue. Spread epoxy adhesive on one side of the tape with a trowel. Saturate the tape with epoxy glue while pressing down firmly with a putty knife. Wrap the tape tightly over the cleaned and finished pipe surface, so that the middle of the tape is over the damaged area. Pull off the bandage with metal tape. You can use a pipe repaired by this method no earlier than in a day. And if the pipe is in a cold room (air temperature 17 degrees and below), then no earlier than four days later.
Repair by "cold welding" method
You can also temporarily repair the formed fistula using a special compound known as "cold welding". Expand the fistula with a drill. Clean the pipe surface and degrease it with acetone. Dry the pipe and apply the compound to it. The time for complete hardening of the composition is 10 minutes.
Rubber gloves should be worn when working with “cold welding” and epoxy glue.
Try to keep the epoxy out of your skin. If this happens, wipe the skin with cotton wool soaked in acetone to remove the glue. Then wash thoroughly with warm water and soap.
If possible, it is worth replacing the steel water supply system with a more modern and perfect one.
The article below will help you independently resolve the issue of sealing fistulas on pipes. The problem of how to seal a fistula in a pipe under pressure is really very urgent.
After all, a leak in water pipes, heating, drainage can occur at the most inopportune moment, and it must be solved quickly and efficiently.
First of all, you need to understand that all the proposed tips are interesting, but, unfortunately, they are not long-term, and the results in the future can be much more deplorable
.
They are not only inexpensive, but also easy to install. Their installation is not complicated, and it is easy to carry out it yourself.
When talking about methods of sealing leaks, a "breakthrough" of a small scale is implied. If the water breaks through with a fountain, then there is only one way out - replacing the pipeline.
Fistula is called pitting corrosion
, which is formed from partial destruction of the material, or from general old age. The result is a hole through which fluid flows outward.
The external visual manifestation of the fistula is swollen paint and rust build-ups. Seeing such a build-up, one should not rush to rip it off, because the size of the damage under it is not predictable.
In general, patching up pitting is not a difficult job, but nevertheless, you also need to seriously prepare for it.
For such events, you will need (experts say that you must always have it at hand):
- Clamp (a couple of pieces).
- Rubber pads (they can be easily made from any materials at hand, such as old boots, thick rubber gloves, bicycle tires, and so on).
- Screwdriver and bolts.
- Epoxy materials.
- Degreasing liquid.
- Emery.
- Cold welding.
The reasons for the appearance of fistulas on a water pipe are most often reduced to one denominator. This impact corrosion
.
The most suitable temperature indicator for corrosive formations is +15 degrees.Most often, pipe-rolling materials in this mode are in the spring, summer and autumn periods.
It also accelerates corrosion damage and water located in the system. Over time, inside metal pipelines, rust builds up.
The metal in such products is becoming more and more thinner every year. And then the moment comes when corrosion breaks through the wall completely. The result is a leak.
When a small fistula occurs, water slowly flows down the pipeline, where a puddle is subsequently formed.
It is necessary to eliminate this problem immediately, without waiting until it turns into a big nuisance. If the leak is small, then it can be repaired under pressure without shutting off the water supply.
Causes of the appearance of fistulas
The reasons for the formation of fistulas in a water pipe are most often reduced to one denominator. This is the effect of corrosion.

It also accelerates corrosion damage and water located in the system. Over time, inside metal pipelines, rust builds up.

It is necessary to eliminate this problem immediately, without waiting until it turns into a big nuisance. If the leak is small, it can be repaired under pressure without shutting off the water supply.
The most common problems that cause a heating pipe to leak include:
- long service life and severe corrosion;
- poor quality installation work, poor joints;
- loads of different types on the components of the heating system.
Since water is constantly under pressure in the pipe, and temperature differences in air act on it from the outside, condensation can form, which leads to metal oxidation and accelerates corrosion processes.
Leaks can form not only in a metal pipeline, but also in a plastic one. Naturally, the problem most often arises as a result of mechanical damage or improper installation, since this material does not corrode.
Leaks in various systems
A fistula in a hot water pipe or any other system that consists of metal pipes can be quickly repaired in the following ways:
Option 1.
Medical bandage and cement mortar. It is cut into pieces, soaked in a previously prepared cement mortar. These bandages are wound around the leakage zone, forming a structure similar to a cocoon.
Finally, the resulting structure is also covered with a cement mortar. It dries up in about one day.
Option 2.
Pieces of rubber. The rubber is cut into strips. Each of them should be slightly longer than the circumference of the pipe.
Option 3.
Food salt and bandage. Typically, this method is used to seal leaks under pressure in couplings, elbows, etc. The leaking area is wrapped with a bandage mixed with salt.
When dissolved, the salt fixes the microleakage. If we compare this method of sealing under pressure, then it is immediately worth noting that it is not as reliable as the first two.
Option 4.
Bandage. This method can be used for pipes under pressure. The bandage is one of the oldest and most proven options. A small car clamp can be used for fistula up to 0.005 cm in volume.
For the clamp, a strip of rubber is cut out, a couple of millimeters wider than the clamp itself. The length of the strip should be one centimeter shorter than the circumference of the pipeline. ...
This whole structure is obliged to completely cover the fistula. Then the clamp is tightened. With these measures, the surface at the place of corrosion must be cleaned.

It should not contain irregularities.If this is not done, then the liquid will pass through the bandage in the area of uneven areas.
Hole sealing process
When the system is worn out, it is advisable to prepare several clamps that have the same diameter as the pipeline. In addition, you need to stock up on rubber for them. In the event that a water pipe fistula appears at night, such preparation will not be superfluous, since the emergency team is unlikely to arrive in a matter of minutes.
If the hole is small, it can be closed using a conventional vehicle clamp:
- A thin tape is cut from a piece of rubber - its width should be 2-4 millimeters more than the same parameter for the clamp. The length of the cut is measured by wrapping the material around the pipe. The excess piece of tape is cut off.
- The clamp is opened and placed on the pipe, then it is not tightly gripped.
- A rubber gasket is placed under the clamp and gently pushed to the place where the hole appears.
- After covering the fistula, the clamp is tightened with a screwdriver or key, depending on the characteristics of the device of the tightening product.
If a very small fistula is found and there is no clamp at hand, the hole can be closed with the end of a match. But this method is used infrequently, since it is rarely possible to eliminate the leak in old pipelines - it only increases in size. Even if the gap is successfully sealed with a match, it must be repaired as soon as possible with a clamp.
To eliminate a serious fistula on the hot water pipe, you will need a more powerful clamp:
- First of all, they turn off the water and drain it from the pipeline.
- Before installing the clamp, carefully inspect the pipe. When its surface is uneven, it should be sanded to prevent fluid from flowing through the roughness.
- A rubber pad is cut out under the clamp and placed on the hole.
From the above information, it is clear that it is quite possible to eliminate the fistula in the pipe with your own hands - no special tools or special skills are required. If you have metal risers, you need to prepare several clamps and rubber gaskets.
Hello dear readers!
You can easily detect a fistula in a heating or water supply pipe by a fountain of water gushing from a riser. Know that after doing this, the problem must be fixed as quickly as possible. Otherwise, due to a small hole, your home will soon float. And with him the apartments located below will set sail.
I will tell you how to fix the problem on your own and quickly, until reinforcements arrive in the person of the ZhEK repairmen.
Sealing a fistula in plastic pipelines
How to eliminate a fistula in a water pipe if it is made of plastic. recently used very often.
They quickly replaced conventional steel products, thanks to a wide range of positive characteristics. These materials are not only easy to install, but also easy to repair when fistulas appear.
You can seal a leak on a plastic blank by using couplings and fittings (part of the line is changed). In this case, a new section of pipe with a cut thread is harvested.
By means of connecting elements, it is installed in place of a site that has become unusable. If you are not sure that all actions have been performed correctly, then you can seek advice from a professional master.
After inspecting the structure, he will give an exact answer whether it is suitable for use, or advise a complete replacement of the damaged pipe.
This method can be applied not only to plastic pipes, but also to metal ones. Only it is impossible to eliminate the fistula in this way under pressure. We'll have to worry about turning off the water in the plumbing system.
In order not to interfere with the repair, it is necessary to turn off the main valve. It is usually installed in a toilet.

What is a fistula?
A fistula is damage to the wall of a pipeline in the form of a crack or through hole. Leaks of this kind indicate that the time has come to replace the pipe section. However, it is not always possible to do this immediately after detecting a leak on your own. While the summoned master arrives, a significant part of the apartment will be flooded with water, not only yours, but also the neighbor's. But the temporary patch is not so difficult to install.
How to brew a fistula in a pipeline with water
How to brew a fistula in a plastic pipe with water can be learned from the method that is attached below.
Unlike the previous version, which could be applied not only for plastic products, this method is only suitable for working with PP pipe-rolling materials.
Actions are carried out using. This tool melts the prepared components and fixes them after cooling down.
To repair minor damage to the site, all remedial actions can be carried out under pressure.
But, for an education that is significant in size, the water supply system will have to be shut off, since it will be impossible to weld the defect under pressure.
Anyone can work with the iron. No special experience is required for this. An instruction is attached to such devices, where the whole process of work is described step by step.
After carefully reading it, you can safely start repairing the PP pipeline. It is not difficult to brew a leak in this way.
Ways to close up a fistula with your own hands
What if the fistula is caught by surprise? Do not panic. Take a look around - for sure in your house there are available means for sealing the fistula:
- bolt;
- temporary or adhesive bandage;
- cold welding.
If you find any of the above, then consider that the problem is solved. Do not forget that the heating medium and hot water are pressurized in the system. Therefore, if possible, shut off the water or heat carrier supply with shut-off valves before proceeding with the repair in a way that suits you.
