To solve the question of how to repair a leak in a sewer pipe, it is necessary to accurately determine the location of the leak and the cause, taking into account the pipe material.

Causes of accidents

Repair of sewer pipes takes place in emergency situations. There are different types of accidents, which means they need to be eliminated in different ways.

If it leaks sewage pipe because of mechanical damage, inevitable major renovation: replacement of the entire pipe or part of it. If the connection is depressurized, minor repairs can be done.

Sewerage leaks, as a rule, due to damage to pipes or defects during their production, as well as at the joints.

1. Joint.

If a sewer pipe is leaking at the junction, you must:

• dry the joint;
• clear of debris, cement or glue;
• seal the gap between the pipes with plumbing linen tape;

• coat generously with plumbing sealant;
• Do not use the sewer for 5 hours.

1. Crack in the coating.
   We solve the problem of how to eliminate a leak in a sewer pipe if it goes through a cracked solution: after drying, we cover all the cracks with silicone, epoxy, liquid rubber and even plasticine.

1. Fistula.
   If water flows out through a fistula in a pipe, then you can temporarily drive a short wooden wedge - a chop or a lead cone - into it, then wrap the pipe with rubber or a bandage and then soak it with epoxy, or make a clamp. Installing a clamp, even a homemade one, is the most reliable option.

Elimination of cracks

From temperature changes in exhaust hoods cast iron pipes shallow ones appear longitudinal cracks. We decide how to seal the sewer pipe separately in each specific case.

You must first slightly widen the outside, degrease and dry the crack, and then cover it with sealant. Then you need to cover the pipe with a heat insulator.

Is the sewer pipe leaking through through cracks?

Let's eliminate radically:

• “cold welding” using a special two-component glue;
• After hardening, we sand the seam and paint over it.

Tighten the coupling - the leak is closed

There are different plugs for sewer pipes.

• Cleaning plug. If you do not use cleaning, you can cover the joint between the pipe and the wedge with sanitary silicone.
  To allow the joint to dry out, it is not recommended to use the sewer for 2 hours. You can dry it with a hairdryer. If the chopper allows water to pass through, you can pull it out, after slightly shaking it, and trim it to insert it more tightly.
  But before you drive the chop in again, it's better to wrap it plastic film from a regular package.

• You can put a plastic plug instead of a wooden wedge, and put a rubber gasket on the plug. How to seal a sewer pipe if it leaks again? You need to seal the plug with the gasket with sanitary silicone.
• If there is a leak at the joint, you need to fill the joint completely, in a circle over the sealing, with gum arabic, that is liquid glass- office silicate glue.

Replacing the damaged area

Often it is possible to eliminate a leak only by replacing the damaged piece of pipe with a whole one.

Necessary tools and parts: metal hacksaw; linen; pipe wrenches; sealing putty; coupling; pipe cutter; union nut.

Progress

• Use a hacksaw to cut out the section of pipe with a leak + 30 cm.
• Let's unscrew threaded connections, clean the thread, remove the cut piece.
• Let's cut a thread on an old pipe. To do this, you need to hold it with a pipe wrench. This will prevent the pipe from deforming and twisting.
• Screw the coupling onto the stationary pipe and find out the length of the replacement pipe, taking into account the length of the thread.
• Having fixed the pipe with a vice, we cut off the required section with a pipe cutter.
• Let's cut a thread on it with a clamp.
• Having wound flax around the thread, seal it and lubricate it with sealing putty.
• We will connect the new section with the old pipe using a pipeline coupling.
• Using a union nut, connect the new pipe to the old one at the other end.

For emergency repairs, the pipe can be wrapped in rubber from a bicycle inner tube and secured with couplings until a major overhaul.

Repair of cast iron pipes

We seal the joints of cast iron pipes:

• winding strands;
• strand settling;
• putty with asbestos cement mortar.

But first you need to clean the pipe to bare metal.

If the service life of the sewer pipes has expired, the system must be dismantled:

• cut the pipe with a grinder to the joint;
• We remove the remaining packing and cement from the socket;
• on the remaining section of the pipe we use a grinder to make transverse cuts - a stop for the lever;
• We insert the pry bar into the resulting grooves and loosen it along the axis of the pipe;
• we take the rest of the pipe out of the socket;
• We place a rubber adapter coupling in the socket;
• We put a plastic pipe in it.

Repair of plastic pipes

• If the surface is damaged plastic pipe repairs are not advisable due to its unreliability and low cost.
• The question of how to seal a sewer pipe, minor damage to it, can be solved in a simple modern way: with sealant.
• Additionally, you can embed shaped parts. Tees are suitable for inserting into a sewer pipe (see details).
• If there is a leak at the joint, it is necessary to replace the deformed seals, lubricating the new ones with silicone.

If the sewer pipe is leaking (see also), you can easily and quickly eliminate the leak using the indicated available means and self-confidence or do.

If in any place sewer system If a leak is detected, then the first natural question that arises is how to repair the leak in the sewer pipe. We will talk about the causes of accidents and methods for eliminating leaks in this article.

Causes of accidents

In case of emergency situation begin repairing sewer pipes. Due to the fact that accidents are different, the approach to eliminating them will be different.

If the cause of the damage is mechanical impact, then most likely it will be necessary to carry out a major repair, that is, replace the entire pipe or its element. If the connection is simply depressurized, it will be enough to carry out minor repairs.

The causes of sewerage leaks are most often associated with the occurrence of pipe defects during their manufacture, as well as after the construction of the system - at the joints.

If a sewer pipe is leaking at the junction, you will need:

• dry the joint;
• remove accumulated dirt, cement or glue;
• close the gap between the pipes with linen winding;
• coat generously with construction sealant;
• wait 5 hours, after which you can start using the sewer.

If it turns out that a pipe is leaking, we will consider what to cover it with, based on their specific situation. If water oozes through a cracked solution, then the cracks that appear after drying will need to be covered with silicone, epoxy or liquid rubber.

If the liquid is leaking through a crack in the pipe, then as a temporary measure, you can drive a small wooden or lead wedge into it, then wrap the damaged area with rubber or bandage and soak it with epoxy or install a clamp. There will be a clamp ideal option, even if it is homemade.

Repairing cracks in sewer pipes

Due to temperature changes, small longitudinal cracks may appear on cast iron pipes.

To eliminate this problem, first of all, on the outer part of the pipe, the crack is slightly widened, dried and sealed with sealant. After this, the pipe is wrapped in a heat insulator.

There are cases when water seeps through through cracks.

In this case, eliminating the leak will be as follows:

• method will do cold welding two-component glue;
• After the glue has dried, we sand the seam, after which it can be painted over.

Getting rid of fistulas

Before you fix a leak in a sewer pipe, you should understand how to fix it.

You can use the first method:

• wrap the damaged area with a rubber gasket;
• tighten with a clamp.

There is an alternative method:

• if a large fistula occurs, you will need to use a repair coupling;
• cut a piece of rubber to the size of the coupling;
• Tighten it well and the leak should stop.

It is worth noting that special plugs can be found on sale. They are installed in cleaning areas. You can additionally put a rubber gasket on the plug. The solution to sealing a cast iron sewer pipe if the leak continues is to additionally seal the plug with silicone.

If a leak has formed at a joint, then the joint is additionally filled with liquid glass, that is, silicate glue, on top of the sealing layer.

Replacing a defective pipe

Often, due to serious damage, it is necessary to completely replace the entire pipe. To do this, you will need to stock up on tools and parts: a hacksaw for metal, flax, pipe wrenches, a sealant, a union nut and a coupling.

The sequence of work will be as follows:

• Using a metal hacksaw, the defective section of the pipe is cut out, plus 30 cm.
• We unscrew all the connections, clean the threads, and remove the cut piece of pipe.
• We make a new thread on the old pipe. To hold it, we use plumbing wrenches.
• We screw the coupling onto the pipe, after which we determine the length of the replacement pipe, taking into account the thread.
• We fix the pipe in a vice and cut off the required section.
• Using a die we cut a thread on it.
• We wrap flax around the thread and lubricate it with a sealant.
• Using a coupling, we connect the new piece of pipe to the old one.
• From the other end we join the new one and old pipe union nut.

If emergency repair of a pipe is necessary, it can be wrapped in rubber from a bicycle inner tube and then secured with couplings.

Repair methods for cast iron pipes

When craftsmen decide how to coat a cast iron sewer pipe, they have several options to choose from:

• wind the strands;
• to settle the strands;
• use asbestos cement solution as putty.

However, before starting any work, the pipe should be cleaned to a metallic shine.

In cases where sewer pipes made of cast iron are morally and physically worn out, they are completely dismantled for replacement.

This work is carried out in several steps:

• using a grinder, cut off a section of pipe to the joint;
• the socket is freed from cement and packing residues;
• the remaining section of pipe is cut with a grinder in several places to make a stop for the lever;
• insert a crowbar into the slots and loosen the pipe along the axis;
• the last piece of pipe is removed from the socket;
• the rubber adapter coupling is mounted in the old socket;
• A new plastic sewer pipe is installed in the adapter.

How to repair sewer plastic communications

Since plastic sewer pipes are quite cheap and not very reliable, it is not recommended to radically repair the damaged surface.

In this case the best option Cosmetic solution to the problem will be to seal it with ordinary sealant.

As additional protection It is possible to insert shaped parts, for example, tees.

If a leak is detected in the pipe at the junction of two sections, then you should simply replace the leaky ones. sealing elements new ones, not forgetting to seal the seam with silicone.

Thus, it is possible to eliminate a leak in a sewer pipe made of any materials using available materials and tools. Use our recommendations and everything will work out for you in the best possible way.
