Repair of sewer pipes: elimination of leaks and sealing cracks

Before you figure out how to fix a leak in a sewer pipe, you need to understand what it can appear because of. No one is immune from such a situation, and you need to act as quickly as possible.

It looks like a crack in the pipe

Most often, water flows at the joints of pipes. The solution to this problem is carried out using organic fiber. Eliminating a leak in the sewer pipe may be necessary even after a long downtime of the drainage system. This happens with plastic pipes when the rubber seal dries out during non-use. The sewerage is flowing, and when the mutual displacement of the pipes occurs, the compensating pipe most often suffers. It is known that polypropylene and PVC are not resistant to mechanical stress, and if you accidentally drop something heavy on the pipe, a crack or a whole hole may well form.

The advantage of cast iron is that it is difficult to corrode, but there is one caveat, a humid atmosphere is poorly tolerated by this material. And if the service life of a cast-iron sewer exceeds 50 years, then it is likely that through holes will appear. Well, the most common cause of a sewer leak is blockage. They can serve as a rag, grease plug and even cat litter.

Instructions for the repair of plastic pipes

The question of how to fix a leak in a plastic sewer pipe often arises. Repair is carried out according to the following scheme:

the pipeline is freed from liquid;
a layer of glue is applied to the place of leakage (it is important to consider the type of structural material);
a patch from an identical pipe is applied on top.

This is how a crack in a plastic pipe is eliminated.

If a sewer pipe is leaking at the junction, then you need to do:

clean the traces of the old winding;
apply a layer of paint, silicone or glue on top of the joint, you get a fixing layer;
tow, polymer film or linen winding is wound on top of it;
at the end, the new winding is impregnated with a substance that provides moisture resistance.

By the way, plastic fittings can simply be soldered to pipes. In this case, a special viscous mass is used.

How are cast iron pipes repaired?

Often on the forums you can read how people repair a cast-iron pipeline, but there is a certain procedure that must be followed. How to fix a crack in a cast iron sewer pipe? There are several ways:

Drive a wedge out of wood.
Close the damaged area with several layers of gauze impregnated with epoxy mixture.
Use bandage rubber for winding, pulling it with copper / aluminum wire (10-20 turns).
Install clamp.

You can also repair a crack in a cast-iron sewer pipe with something else, this is “cold welding”. The above methods can be combined. The same can be done if a cast-iron sewer pipe has burst.
