A pipe is leaking in the bathroom - what to do: reasons, ways to eliminate the leak

Any renovation in the bathroom should begin with an audit of the plumbing system. If the pipes have been serving for more than 15 years, then, most likely, the time has come to replace them. This will be the first stage of the renovation. But what if the repair is not yet planned, and the pipe in the bathroom is already leaking? The answer is obvious - it is necessary to take urgent measures to eliminate the leak, otherwise the neighbors will be flooded and in addition to repairs in their apartment, they will have to make repairs too.

Plumbing in houses and apartments is most often made of three types of pipes:

metal;
metal-plastic;
polypropylene.

Let's try to figure out how to repair the current pipes of each of these types. At the beginning of any plumbing repairs, the inlet water must be shut off.

How to repair a leaking metal pipe

It should be understood that if a steel pipe is leaking, then this is a sure sign that it needs to be replaced. However, the replacement was done by professionals, and this can not always be done in the shortest possible time. In the meantime, it is urgently necessary to eliminate the leak. You can do this with your own hands using a special device - a repair clutch.

Coupling for repairing three-quarter steel pipe

When buying a repair coupling, you should take into account that they differ in size - different couplings are needed for pipes of different diameters. To find out what diameter is needed, wrap a thread around the pipe to be repaired and measure the length of the full circle, then divide the resulting value by 3 - get the desired diameter. A size of the order of 20 mm of the outer diameter corresponds to half an inch of the inner diameter, 25 mm - three quarters, 32 mm - one inch. Having found out the diameter, in the store we buy a repair coupling of the appropriate size and proceed with the repair.

We unscrew the four bolts connecting the halves of the coupling.
We put a rubber strip on the place of the leak and squeeze it with the halves of the coupling.
Tighten the bolts until the leak stops.

Repair sleeve installed at the leak site

Strictly speaking, this is the end of the repair of the leakage of the steel pipe. It is important to remember that the measures taken are temporary - the maximum, how long the repair coupling will last, is six months. Therefore, you should as soon as possible invite specialists who will change your metal pipes for more modern ones - metal-plastic or polypropylene.

Possible reasons for the leak

Today, plastic and metal siphons are used in the sewage system. Plastic devices are made up of several parts. They are connected using union nuts, rubber gaskets and cuffs. For assembly, there is no need to use tools, all actions are performed by hand.

Steel siphons today can be found quite rarely, except in old houses. They are durable and reliable. The steel pipe in the bathroom is attached to them with bolts; gaskets made of sheet rubber are installed between the drain fragments.

If the drain system is leaking, then the reasons for this may be the following:

Mechanical damage. These can be cracks and chips. This happens from impacts, sudden movements or strong lateral loads. As a rule, flasks crack when a loose shell is pushed to the side by inadvertent pressure.
Incorrect assembly. Quite often, novice home craftsmen make mistakes when installing a sink with a drain. Most often, they skew the threads at the connection or do not tighten the union nuts to the end. Sometimes the gaskets do not match the pipe diameter.In some cases, incorrect joining is performed.
Factory marriage. This happens if you buy goods at unverified retail outlets. Poor-quality siphons can have cracks in the body, irregular geometry, sagging and dents. It is through them that the drained liquid can flow.
Dry gaskets. The rubber used for their manufacture has a limited service life. Over time, due to the effects of cold and hot water, it becomes solid, loses its shape and decreases in volume. This leads to crevices and leaks.

If the siphon leaks, it can be completely replaced or repaired. Installing a new device does not always give the desired results. You can buy a marriage or make mistakes during assembly. Resolving an emergency can take much less time than packing up and going to the hardware store. In addition, doing it yourself allows you to save a certain amount of money that can be spent on other purposes.

Elimination of a leak in a metal-plastic pipe ↑

Unlike metal pipes, a leak in a reinforced plastic pipe does not necessarily signal the need to replace it. Often the cause of a leak is its mechanical damage or a loose fit of the fitting. In the second case, it is usually sufficient to tighten the retaining nut to stop the burrowing. If the above measure does not help, the fitting should be replaced. If the pipe itself is damaged, then a connecting sleeve should be cut into the place of leakage.

Collet coupling for metal-plastic

The repair process should be carried out according to the following algorithm:

Look at the pipe markings to find out the diameter.
Buy a collet sleeve of the appropriate size from a store.
Cut the pipe right where the leak is.

This is how a metal-plastic pipe is cut with special scissors. If the gap is too large, it is better to completely remove the damaged area.

Finished incision with removed damaged area

Unscrew the collet nut and slide it over one end of the pipe. Put on the sealing brass ring next.
Insert the collet fitting as far as it will go.

Installation of a metal-plastic coupling

Do the same for the second end.
Tighten the retaining nuts first by hand and then using any suitable wrench. As a result, you will get a collet coupling in the place of leakage.

Collet coupling installed in place of leak

Since the entire metal-plastic system is assembled on fittings, the appearance of another collet connection in the water supply will not affect the service life of the entire system. The described method allows you to forget about leaks for a long time, however, if the problem repeats over and over again, then it is still time to change the pipes, that is, call specialists to carry out a major overhaul of the water supply system.

Do-it-yourself temporary elimination of a weak leak

It also happens when the reason for the pipe leak in the bathroom is not so terrible and serious, so there is no particular need to change the pipe. Then you can try to fix the problem on your own. There are two solutions for this: cold welding or bandage.

Option one - cold welding

Now on sale there is a very useful substance in everyday life called cold welding. Such welding, without the application of special efforts and skills, is capable of very reliably interconnecting materials such as metal, glass, plastic, wood and others. Cold welding is perfect when the pipe does not flow much under the bathtub, but only oozes.

Turn off the water and put on rubber gloves before doing this welding. Then clean the damaged pipe well, thereby freeing it from dust and dirt.Wipe the pipe dry and degrease the surface thoroughly with acetone or alcohol. After that, remove the weld (so-called punches) from the packaging and press it as hard as possible against the deformation of the pipe. It is best if a man does it. Within about 20 minutes, the weld will set and the surface will be restored. All you have to do is wait a little and cover it with paint.

Option two - clamps and bandages

Another equally good way to eradicate the pipe leakage problem with your own hands is a clamp or bandage. The clamp is used when it is necessary to block the water leak in the pipe for a while (usually for several days). The bandage is used in the same cases, as well as when condensate is constantly collecting on the pipe.

To repair a pipe with a hose clamp, you will need a regular metal clamp, which you can buy inexpensively from the market or any hardware store, and a piece of rubber to act as a gasket. Moreover, a piece of rubber should be about 2 times larger than the damaged area. If the problem needs to be solved urgently, you can use ordinary wire instead of a clamp. Shut off the water. Clean the damaged area on the pipe and wipe dry. After that, firmly press the rubber to the damaged area and fix it as tightly as possible with a clamp or wire.

To put the bandage on the pipe under the bathtub, you must first purchase it. There are many pipe bandages on sale now. Keep in mind that it must be the correct size and made of waterproof material. The best option is fiberglass. Usually, the bandages are selected according to the pipe diameter. But its width should be about 7 cm more than the damaged area. In this case, the bandage has a longitudinal cut, with the help of which it is put on the pipe.

Before installing the bandage, close the water valve, wipe the pipe dry and, if necessary, clean its surface. Coat the inside of the pipe and bandage with epoxy or special waterproof glue. Put the bandage on the pipe carefully and fix it very tightly with a metal clamp. Depending on the width of the place damaged on the pipe, you can use two or even three clamps instead of one. This is necessary for greater reliability. After two days, when the glue or resin is completely dry and set, you can open the valve and use the bathroom.

Repair of a polypropylene pipe ↑

Polypropylene plumbing is perhaps the most reliable and durable, since all connections are thermally or chemically soldered, forming a single monolithic system. Therefore, the leakage of a polypropylene water supply system is possible only in two cases:

Poor soldering of elements. It may show up after a certain time, after the introduction of the entire system into operation. If this happens, then you will have to redo an entire section of your plumbing. If you do not have special skills, it is better to resort to the services of specialists.
Mechanical damage. There can be many options for how this could happen, but the solution is always the same - soldering a polypropylene coupling sleeve into the leak.

Polypropylene coupling

The process of soldering the coupling is much similar to the installation of a collet coupling on a metal-plastic pipe.

From the marking on the pipe, we determine its diameter.
In the store we buy the necessary coupling.
We cut the pipe at the leak.

We cut a polypropylene pipe Thermal brazing of polypropylene pipes occurs much more often than chemical brazing, so we will consider it. You need a special soldering iron. We are looking for it either from friends, or we rent it - many shops give a soldering machine for a very reasonable price for a while. We install Teflon nozzles of the required diameter. We heat the device. On the one hand we put on the coupling, on the other we insert the pipe.

Initial emergency measures

Usually pipes, especially plastic ones, do not deteriorate by themselves. They do not burst, rot or crack. However, if you installed them for a very long time or the installation was done poorly, they may begin to ooze systematically. The best option, of course, would be to replace the pipe and the piping adjacent to it. But not everyone can afford it, and it cannot be done instantly. And you still have to stop the leak. Consider then the first steps in this problem.

First you need to completely shut off the water valve. If you live in an old Khrushchev, which is now a very rare occurrence, then you will have to shut off the water throughout the house. Usually the valves in this case are in the basement, and you just can't get to them, and it is quite possible to have time to flood the neighbors during this time. It is very good that now almost all apartments have their own valves, which can be closed without difficulty.

Internal sewerage scheme.

It is necessary to shut off cold water and hot water too, just in case. And this should be done as quickly as possible. That is why it is so important that access to the valves is always free. And if you are already thinking of changing pipes, make sure that the valves are installed in the toilet near the toilet. This will ensure always easy and quick access to them.

If you turn off the valves and the water stops flowing, this is a good sign. This means that the pipe is damaged up to the valve. Now all that remains is to call a plumber and transfer the solution to the problem into his experienced hands.

But there are also cases when the pipe flows under the bathroom in a place where closing the valve may not give any results. A clear sign: the water continues to flow even after shutting off. In this case, call the emergency service immediately! In the meantime, while you are waiting for her arrival, you need to put a container under the leak so that all the water is collected in it.

Another option is to temporarily stop the water leak by tying the pipe with a rag. But the container still has to be substituted. You can also tape the pipe as tightly as possible. And to keep the fabric or scotch tape more secure, you can sprinkle a little table salt on their surface before wrapping. All the puddles formed as a result of the leakage of the pipe under the bathroom must be wiped off with rags as soon as possible so as not to flood the neighbors and create even more problems.

A universal way to eliminate leaks ↑

In conclusion, we will describe another way to eliminate leaks. It is universal, that is, it fits any type of pipe.

We take an ordinary rubber household glove. In the part opposite to the finger, we cut a tape 10 - 15 mm wide with scissors in a spiral.

How to get a rubber band from a household glove

We wind the resulting strip with an interference fit over the leak, in fact we bandage it with a rubber band.

We fix the end in any available way, for example, wrap it with wire or rope. The main thing is that the tape does not unwind. The leak is eliminated.

Video tips for connecting metal-plastic pipes

The most important thing when repairing pipes with your own hands is to clearly understand whether this is a temporary solution or a permanent one. If the leak is caused not by mechanical damage, but by natural wear and tear of the pipe, any measure can only be temporary. Such a flow will intensify, therefore, it is necessary to invite specialists as soon as possible to radically solve the problem.

Pipe leaks from time to time accompany their operation: most often the causes of such phenomena are corrosion or deformation. Thanks to the use of polypropylene, polyethylene and metal-plastic pipes, the problem of corrosion was solved, but the threat of mechanical damage remains relevant in this case.

A siphon leaks under the bathroom - what to do?

First, let's try to figure out why puddles appear under the bathroom and how to avoid it. The most common reasons for a siphon leaking under the bathroom are as follows:

O-ring rubber wear: stretching, displacement, cracking.
Violation of the integrity of the overflow pipe.
Loose siphon screwing after cleaning.
Blockage formation.
Looseness of the drain and overflow pipe joint.
Loss of sealing of the connection due to damaged gaskets and stripped threads.

How to fix a leak:

If the O-ring is worn or deformed, replace it with a new one, if it is displaced, put it back.
If the overflow pipe is damaged, replace it with a new one.
Is the siphon dirty? Unscrew it, first placing a container for water, then clean it with a screwdriver or a long wire. Assemble the device in the reverse order.
If the sealing of the junction of the drain and overflow pipes is broken, seal this area with ordinary silicate stationery glue.

Important! If the sealing of the siphon connections is broken, treat the joints with a sealant. Winding up the thread with tow or silicone tape also helps.

How to start fixing a leak

Standard situation - it was discovered that a pipe is leaking: what to do in such cases? The first step is to pinpoint exactly where the pipe is flowing. If a sink, washbasin or bathtub drain leaks, the reason for this phenomenon is usually a poor-quality connection of the drain hole, siphon and the entrance to the pipe.

In this case, to eliminate the problem, you will need to tighten all threaded connections through which the sewer pipe flows. Sometimes it helps to replace the gaskets at these joints.

How to seal a leak in a plastic pipe?

Everything is very simple:

Select a piece of plastic pipe of suitable diameter and cut to length.
Cut off about a third of the surface to its full length.
Sand the inside of the surface and apply glue to it.
Place the resulting plastic strap over the damaged area.
Press down on the clamp and wait for the glue to harden.

Bolt in hole

If the leak is provoked by a fistula in the pipe, drill a small hole in the place of the fistula and screw in a bolt moistened with oil paint. This method can be used for new large diameter pipes. If the pipeline is old, then all attempts to screw in the bolt will only lead to the fact that the hole will increase.

If the pipe is leaking at the junction

Using the caulking method for cast iron pipelines

If leaks are detected at the junctions of cast-iron sewer pipes, you should prepare for a rather complicated procedure for eliminating the problem (read: "How to repair a crack in a cast-iron sewer pipe - reliable and proven methods"). In this case, much depends on the quality of the docking work.

If stamped with lead, the procedure is as follows:

Strip the docking area until clean metal appears.
Stamp the gap using lead cones. This is done with a blunt chisel, since in this case it is quite easy to seal the gap with soft lead.

What to do if the pipe in the toilet is leaking:

Clean the joint from the old mortar using a narrow chisel and hammer. Care must be taken not to damage the pipe.
After removing the old seal, the gap must be well cleaned.
For new clogging, tarred strands and an aqueous solution of cement are used, in a ratio of 10: 1 to water. Before clogging, the strands are treated with a special substance, which includes cement and asbestos, in a ratio of 7: 3. During kneading, a little water is added: the finished solution should be like plasticine.

Elimination of leaks at the joints

The first step is to determine exactly where it flows from.If water collects under the sink or under the drain in the bathroom, then first of all, you should check the quality of the connection between the drain and the pipe.

Advice. Often, the problem of leakage can be solved by the process of tightening all threaded pipe connections or replacing rubber gaskets at the connection point.

Cast iron pipe joints

In order to understand how to cover up when the joints of cast-iron sewer pipes are leaking, you should first of all determine how the connection was sealed.

If the connections of the parts of the sewer cast-iron pipeline were minted with lead, then the following must be done:

The junction is cleaned to pure metal;
The gap is minted with lead... Lead cones are chased with a chisel. The soft metal compresses easily into the crevice.

If the joint was sealed with cement, then the following instruction should be implemented in practice:

Remnants of old cement are removed from the surface using a narrow chisel and hammer;

After removing the material, the gap itself is cleaned;

New tarred strands are hammered into the gap and covered with a fresh layer of cement mortar.

Advice. Before driving, it is recommended to treat the strands with an asbestos-cement mixture with the addition of water in the proportions of asbestos / cement 3/7. The putty should be the consistency of soft plasticine.

Sealing the joint with cement

If it turns out that you have a sewer pipe leaking in the toilet right along the joint and of everything you can cover up, you only have cement left from the repair, you should not be upset because cement is perfect for this purpose.

In this situation, proceed as follows:

The joint is carefully cleaned, the old sealing material is removed;

Advice. Do not use a heavy tool for this, so as not to damage the pipeline.

For further work, we prepare the following materials: bandage, cement;
We knead the gruel from water and cement;
We dip the bandage into the created solution and wrap the leaking joint;
After the bandage with cement has hardened, we clean the joint with sandpaper.

Elimination of leaks at the junction of pipes with cement

What to do if a pipe is leaking and only cement is available from all possible materials?

In such a situation, the work is carried out as follows:

Cleaning of the pipe joint is carried out, with the obligatory removal of the old seal. In order not to damage the pipes, it is better to refrain from using a heavy tool.

Next, you need to get a wide gauze bandage. The cement is mixed with water to make a gruel. A bandage is immersed in the resulting solution.

The same cement mortar is used to process the pipe joint, after which a bandage is wound there.

The hardening of the seal usually lasts for two hours, after which it can be cleaned with sandpaper and painted.

In cases where a leak was detected directly on the pipe body, a completely different algorithm of actions will be required.

Elimination of minor defects in a cast iron pipe

Connection diagram of cast iron pipes.

It also happens that a defect has formed on the still normal cast-iron pipe. And you still do not want to change the only pipe for plastic or do not have enough funds for this. There is also a good way out of this situation. But it works only in those cases when a minor defect has formed on the cast-iron riser (the so-called small "fistula") and the water only flows slightly under the bathtub without flowing out in a stream. Of course, in this case, you can use an ordinary clamp. But if you think about it, then by and large it is not really needed here. You can fix the defect in a simpler way, using ordinary cement.

To do this, first turn off the water and wipe the pipe.Then take sandpaper and carefully clean the area of the defect. Use a rag to shake off the dust and lightly wet the surface. Take a small handful of dry cement and apply over the heat of the pipe. After the cement is wet, apply some more. Do this until the cement is no longer soaked. Due to the fact that the cement adheres well to the metal, the site of the defect will be completely tightened and will not leak.

If the problem is more serious and there is not a fistula on the cast-iron pipe, but a crack, then you need to make a gasket of bandage and cement. Alternate the layer of bandage and cement, going around in a circle about three times. It is more reliable to hold the metal together. It should be noted that the elimination of a defect on a metal pipe in a bathroom with the help of cement requires waiting about three days, during which the cement will set. Only then can you use the riser.

The next way to prevent the metal pipe from leaking is to wrap it with a rubber band. You will need either a medical harness or elastic rubber from a bicycle tube. Then you simply wrap the leak with this bundle and secure everything with wire. For greater reliability, it is recommended to wrap the problem area with a bandage on top and paint it with oil paint. But if the pipe is flowing very tightly to the bath itself, this method will not work.

Install the bandage

If the pipe is leaking in the bathroom, a temporary solution is to install a bandage. Before that, you need to determine what kind of damage will have to be dealt with (fistula or leakage), and where exactly it is located.

The rubber band is applied in this way:

A rubber gasket is installed on the emergency section of the pipe.
After pressing firmly against the pipe, fixation with a clamp is applied.

The clamp can be purchased without any problems in the store, but it so happens that at the right time it is not at hand. In this case, the clamp can be made by yourself, or you can use a wire, bundle, rope or hose instead.

The bandage rubber can be an old rubber boot, from which the shaft is cut off. The same goes for the rubber hose, bicycle tube. The width of the band is made depending on the diameter of the pipe being repaired.

A metal pipe is flowing - what to do

Leaks in such products, as a rule, occur at the joints. The method of its elimination directly depends on the connection method:

Lead hammering - it is necessary to clean the joints until a pure metal appears, then press new lead elements into the joint with a chisel. Due to its softness, lead easily fills all gaps near the joint;
Sealing with cement - the leak is cleaned of old cement, after which new tarred strands are clogged and cemented. If it is not possible to use resin, a different method is used - an ordinary bandage is dipped in highly diluted cement, after which a pipe is wrapped with it. After hardening, the treatment site is thoroughly cleaned and painted with waterproof paint.

Elimination of leakage in the pipe body:

Installation of a bandage - it is a regular rubber gasket that is tightly pressed against the damaged area with a clamp. The more the band is pressed against the pipe, the better the cause of the leak will be eliminated. Special bandages can be purchased ready-made in specialized stores;
Gluing - a piece of rubber, plastic or fiberglass is used to fix the leak, which is glued to the profile with epoxy glue. Before this procedure, it is necessary to shut off the water supply and thoroughly clean the damaged area;
Driving in a wedge - Leaks can be stopped by driving in a small wooden wedge. Of course, this method is temporary.The wedge is driven into the pipe with a hammer, but accuracy and precision are required here, since there is a possibility of serious damage to the system.

A wide range of plumbing works is the main activity of our company. Thanks to our professionalism and responsibility, we are able to solve problems of any profile, as well as carry out high-quality repairs of various plumbing equipment. We work in Moscow and the Moscow region.

Using a wooden wedge in the bathroom

There are situations when a high-pressure leak is formed, but there is no possibility of water shut-off: how to make sure that the pipe does not flow? A bandage in such a situation usually does not help either.

If the leak is caused by a fistula, it can be repaired with a small wedge-shaped wooden peg. The size of its tip is made the same as the resulting hole in the pipeline.

A peg with a sharp end is inserted into the fistula, after which it is hammered in with a hammer. This temporary measure allows you to buy the time required to call the emergency service.

The drain is leaking in the bathroom, what to do? Leak in the pipe body

Here, the troubleshooting methods are somewhat different than when the joints are leaking. There can be several ways. Choose the one that suits you best.

Bandage

Installing a bandage is one of the ways to temporarily eliminate a leak from the pipe body. The essence of the repair is to find the damaged area and apply a rubber bandage. The sequence of the procedure is as follows:

Place the rubber pad over the damaged area.
Press the gasket against the pipe and secure with a hose clamp.

Important! Clamps are commercially available, but, if necessary, you can make them yourself. The material for the bandage can be: a rubber hose, an old rubber boot, a bicycle tube, etc. The width of the band is determined based on the diameter of the pipe.

Wood wedge

Sometimes there is a situation that is called a stalemate. The pipe is leaking, the water pressure is large, it is impossible to shut off the water supply, and the clamp does not hold. A small wooden wedge in the shape of a cone helps to solve the problem, at least temporarily. Make the wedge in such a way that its sharp part matches the size of the hole:

Insert the sharp end of the wedge into the hole.
Drive the wedge carefully into the pipe with a hammer.

Of course, this is a temporary measure, but you will gain time to call the master.

Hole sealing

This is the same bandage, only adhesive. The algorithm of actions is as follows:

Shut off the water supply with a tap.
Dry the problem area with a construction hairdryer.
Find the right elastic material. It can be fiberglass, rubber, plastic, etc.
Using epoxy glue, glue the material to the emergency area.

Important! The width of the rubber band is determined at least 1.5 times the pipe diameter. If fiberglass is used, then cut off such a piece so that you can wrap the problem area at least 5 times.

Apply the adhesive to the bandage material with a spatula or brush. Until the glue is completely cured, press the bandage with a clamp or tie. At a temperature of 25 degrees, the glue hardens for 24 hours. If the air temperature is 15 degrees, the glue will harden for about 3 days.

Sealing a pipe in a toilet

A leak in the pipe can also be repaired with an adhesive bandage.

The procedure in this case is as follows:

The water in the pipe is shut off by a valve.
A hairdryer is required to dry the damaged area.
The selection of a dense flexible material of the required size is carried out. It can be rubber, plastic, fiberglass, etc.
Epoxy glue is required to glue the patch to the leak.

When using fiberglass, the cut piece should be enough to wrap the pipe at least 5-6 times.In this case, the width of the band should exceed the pipe diameter by at least one and a half times. It is more convenient to apply glue to the bandage with a brush or spatula.

Having wound the bandage fabric on the pipeline, until it is completely dry, it is fixed with a tie or a clamp. Drying of the glue usually takes 24-72 hours. In this case, the air temperature should be at least + 15 degrees.

If the connection to the drain under the bathtub oozes

Breakthrough of water between the gander or at the junction, what to do. We solve the problem as follows:

shut off the water;
unscrew the pipe from the drain, substituting a container for collecting water;
clean the cavity inside with a brush, a washing vacuum cleaner;
heat a piece of pipe and the drain point with a blowtorch until steam stops flowing, which will mean complete drying of moisture;
sand the places on the gander and drain with sandpaper;
degrease with acetone, wipe with a dry cloth;
apply a piece of silicone to the pipe and the bottom around the gander;
attach the gander to the bottom of the bath, wrap it around the circumference with a serpentine mesh, on top - another layer of silicone;
wrap with construction polyethylene;
wait 2 days until it is completely dry, the silicone and polyethylene set, and check if the pipe is leaking.

With proper dismantling, the structure will still serve for at least 3-4 years.

If a metal pipe is leaking

It often happens that a pipe in the bathroom has flowed: what to do so as not to flood the apartment and the neighbors below?

In this case, proceed as follows:

The first step is to cut off the water supply.
Cut off the damaged section of the pipeline using a hacksaw or a grinder. The cut is made with an indent of 30 cm in both directions.
Unscrew the threaded pipe connection adjacent to the damaged area.
Threading is carried out at the cut off stationary end of the pipe. It is convenient to use a gas wrench to hold the end of the pipe.
A sleeve is screwed onto the threaded end.
A measurement is taken of how long the new pipe should be, taking into account the threaded section.
To make the insert, use a pipe of exactly the same diameter as the old one. The produced section must be equipped with threads at both ends.
A sleeve is used to connect the new section to the pipeline, and a pipe wrench can be used to hold it.

Before screwing on the coupling, it is necessary to seal the threaded sections of the cut, using flax, a sealing putty, or a special tape-fumigant for this. In addition to repairing metal pipelines, leaks on pipes made of other material can be eliminated in the same way. In the event that it is not clear what to do if the pipe is leaking, it is best to seek help from professional plumbers.

Initial solution to the problem

Plastic pipes are installed everywhere, because they are not demolished. For decades, cracking, decay, corrosion will not occur, although the joints are weak and can begin to leak over time.

The main reason is poor quality installation. To solve the problem, the steps are as follows:

We close the tap with cold and hot water. Fortunately, the valve is installed directly in the apartments, and not in the basement of some old Khrushchev houses.
If the water still oozes after closing the valve, then we try to tighten the threaded connections.
We replace the gasket at the joint in the event of a leak directly from the sewer pipe.

If the methods do not work, then it remains to call the plumber, the emergency brigade. Before their arrival, place a container under the leak to collect water or tie it tightly with a coarse cloth, tape, sprinkling a little salt on the pipe surface.

We invite you to familiarize yourself with Sealing joints between ceramic tiles

If a metal pipe is leaking or leaking and there is a grinder at hand, a hacksaw for metal, then, as a solution to the problem:

shut off the water;
cut off the damaged area, stepping back 25-30 cm in both directions;
remove the threaded connection located near the damaged area;
cut the thread at the end of the cut pipe;
measure whether the segment is suitable taking into account the length of the threaded section;
connect the segment to the common pipeline;
wrap with a seal (putty, linen, fumka tape);
screw on the coupling.

When replacing pipes for the period of a major overhaul in an apartment, residents are advised to install a valve or make sure that it is located directly in the toilet room near the toilet to ensure unhindered access to it in case of a leak, and a quick troubleshooting.
