How to fix a sewer leak - how to fix a pipe

Most owners of apartments and houses are gradually starting to switch to plastic pipes for sewer systems. Despite the increasing popularity of this material, cast iron pipes are also in demand, and it is not uncommon to see sewers made from these pipes in the house. If problems arise, it is necessary to start first of all from the material from which the pipe is made. How to fix a leak in a sewer pipe will be discussed in this article.

How to fix leaks in plastic sewer pipes

With PVC pipes, everything is quite simple: it is enough to accurately localize the problem, and its further solution will immediately appear on the surface.

There are two areas where a sewer pipe usually leaks in a toilet or other location:

1. Whole section of the pipeline. If a section of plastic pipe is damaged, the best solution is to replace this segment. Practice shows that the implementation of this method will give much better results than tightening the pipe with various clamps and gaskets. In addition, such pipe repairs are carried out extremely quickly, and the cost of work is low.
2. pipeline joint. If the sewer pipe is leaking at the junction, then the cause of the leak in this case is usually damage or displacement of the gasket, and it must, accordingly, be replaced or put in its place, for which the pipes will have to be disconnected. Those. in this case, sealing of the system is required (read: "Sealant for sewer pipes - what and how best to seal"). If the socket itself is damaged, due to which the joint of the sewer pipe leaks, then the sewer leak can be eliminated by replacing this pipe section.

Plastic sewer pipes have a lot of positive qualities. For installation, such products are ideally suited, since they are quite light and mounted without problems. In addition, when mounting plastic pipes, sections of different lengths can be used, since the couplings allow them to be connected completely freely. If a sewer riser made of plastic leaks, then repairs are quite easy.

If a cast iron sewer pipe is leaking

But before you fix the cast-iron sewer leak, you have to sweat. With cast iron pipes, everything is more complicated, and if they leak, solving the problem can become difficult. The first step is to find the location of the damage. In order for the search to be possible, the room must be cooled to 15-18 degrees - otherwise condensation will necessarily occur on the pipes, preventing the location of the leak. When the problem is found, you can begin to solve it. Before you fix a sewer leak, you must first turn off the system.

Of course, the best solution lies on the surface: take the opportunity and replace all the cast-iron pipes in the house with plastic ones (read: "Replacing a cast-iron sewer with a plastic do-it-yourself"). If this option is not suitable, then it is necessary to repair the damaged area (in more detail: "Repair of cast-iron sewer pipes - methods and options"). How to fix a damaged piece of pipe?

If the pipe is damaged in a straight section, the leak is eliminated using:

• a clamp with a rubber gasket, which can be purchased at a store or made by yourself;
• a piece of cloth impregnated with oil paint, varnish or epoxy glue, wrapping it around a leaking pipe;
• a fabric patch covered with a rubber strip and wired to the pipe (read also: "Removing blockages in sewer pipes - do-it-yourself cleaning").

Whichever option is chosen, before fixing a sewer leak, it is necessary to clean the surface of the pipe to be repaired, and only then fix the leak.

When cast-iron pipes leak at the junction, the repair is carried out as follows:

• the junction is well cleaned;
• the work surface must dry before repair;
• the cavity between the pipes is filled with sealant;
• when the sealant is completely dry, the sewer can be used again.

Sometimes people have a question: how to cover up the crack that has arisen? The answer always sounds the same - sealant. You can read more about the types of sealant in the article on this topic.

If a leak occurs at the place where the plug was installed on the cleaning, the troubleshooting will look like this:

• the plug (usually made of wood) is replaced with a plastic one, and before installation it must be put on a rubber gasket;
• the plug can simply be replaced with a new one by first wrapping it in several layers of polyethylene.

Eliminate sewer odor

If a leak in the sewer pipe could not be found, and the smell of sewage is still carried into the room, then the problem may lie in microcracks or leaky joints. Even if the pipe does not flow, and the joint of the sewer pipe does not flow, the best solution would still be to completely replace the cast-iron pipes with plastic ones.

To do this, follow these steps:

• first, the required number of plastic pipes is calculated;
• before starting work, the sewerage is turned off;
• now you need to reach the point of connection of the internal pipeline with the riser;
• the joint is cleaned to simplify further work: the old connection can cause a lot of trouble during dismantling;
• cast iron pipes are dismantled;
• a new pipe is connected to the riser (rubber gaskets can be used to fix it in place);
• then you can change all other pipelines;
• the joint between the riser and the internal sewerage is treated with a sealant to prevent leakage.

When the sealant hardens, the sewer will be ready for use. See also: "How to close the sewer pipes in the toilet and bathroom - options and methods".

This article described in detail how to deal with a leaking sewer, and how to fix a leak in a sewer pipe. If everything is done correctly and the right materials are used, then no problems will arise in the future.
