Replacing pipes in a private house or apartment: how to

No matter where you live, in an apartment or in your own home, over time you will need to replace sewer pipes, plumbing or heating. Various factors affect the duration of the pipe life. For example, if we talk about plumbing, then everything will depend on the material of the product and water quality.

More and more homeowners, installing a system of drainage or water supply, prefer products made of metal. Consider the features and characteristics of this material when used in specific systems, as well as the process of installing or replacing pipes.

Installing a new plumbing system

If you do not know how to replace the pipes with plastic ones in the water supply system, then the following simple instruction will help you with this.

We start with preparation for installation work:

• Dismantle the old wiring. If you still have Soviet pipes made of cast iron, use the grinder.
• Make a drawing of the future layout, where specify all the bends and branches. This will allow you to purchase the required number of pipes, as well as connecting elements (couplings, adapters, etc.).
• Prepare the following tools for the job.: pipe bender (preferably spring-loaded), pipe cutter, wrench set, calibrator.

Now you can proceed to installation work. The whole process is very simple and does not take much time.

So:

1. According to the drawing, we cut the pipes.

Note! In order to increase the reliability of the coupling connection, the edges of each segment should be processed using a calibrator.

1. Now we connect the segments together. This is done as follows: a sealing ring is put on the pipe, and then the end is inserted into the fitting, after which the nut is tightened.

Note! Tighten the nuts carefully, without undue diligence. Otherwise, you may damage the thread or the fitting itself.

Installing a new sewer system

Replacing sewer pipes is somewhat different from replacing water piping, but is also a simple procedure. The preparatory stage here is almost the same: we dismantle old pipes, draw up a drawing and according to it prepare the necessary materials.

Separately, it should be said about the disassembly of the riser. If the pipes that are located remotely from the tee can be simply broken or broken (after all, the cast iron is brittle), then it should be wired carefully near the riser.

Make sure that small chips or pieces of pipe do not fall into the sewer. To do this, cut the pipe with a grinder at a distance of 20 cm from the socket. As a rule, the remaining segment is easily removed.

After proceeding to the installation work:

1. Need to start from the riser. In the pipe that comes out of the floor, a tee is inserted. Use the cuff if the holes are diametrically different.
2. To check all the details of the riser, is "fitting." To implement the "fitting" pipe should be put on the compensator until it stops.

1. The entire structure is connected to the tee and a part of the sewage system that protrudes from the ceiling. Please note that the "fitting" is carried out without gaskets.
2. While the structure is installed in the “test mode”, mark the places for future fastenings, and also install the clamps at the top and bottom.
3. Now the structure is reassembled and re-installed, but with all the seals.

Tip! The pipe assembly process can be facilitated by brushing the end of each trim with liquid soap.

The advantage of using metal-plastic pipes in the systems of water drainage and supply is the low price, as well as the simplicity of their connection by means of rubber gaskets. However, experts advise to further treat the joints with silicone sealant. This will increase the strength of the connections.

Types of fittings for connecting metal pipes

The modern construction market offers several types of pipe fittings, without which it would be difficult or impossible to replace metal pipes with plastic ones with your own hands. The table describes the types and characteristics of such connecting elements.

Conclusion

Summing up, it should be noted that the replacement of pipes for heating, drainage or water supply is not a difficult process. Subject to the availability of all the necessary tools, this task will be within the power of an unprofessional master.

Consider that it is better to carry out similar works in a planned order, but not to wait until something fails. More information can be found in the video in this article.
