Replacement of pipes in the toilet and in the bathroom. Brief instruction

At present, very often the old iron pipeline is replaced by a new metal-plastic or plastic one. This option has a lot of advantages, the main of which is the possibility of self-installation.

Materials and tools needed to replace pipes

Replacement of pipes in the toilet and bathroom requires the following tools:

• Bulgarians with an installed disc for metal - with its help cutting old pipes and fasteners;
• A clamp of a hand, the diameter of which completely coincides with the size of the riser (about 1 inch) or any other tool that can be threaded on a metal pipe in an apartment located on the upper or lower floor;
• Perforator, necessary to drill the holes for fastening or, if necessary, lay the pipe through the wall;
• Electric soldering iron complete with nozzles and pipe cutter;
• Roulette, chisel, hammer, marker and screwdriver.

Replacement of sewer pipes in the bathroom and toilet is impossible without two adapters connecting the metal pipe and plastic, 1/2 inch polypropylene pipes , as well as tees, splitters, fittings, screws, fasteners, technical petrolatum, fumlents, etc.

Preparatory moments

If the owner of the apartment is not a professional repair worker or plumber, a carefully calculated scheme of the length and structure of the future water supply will be required.

In this case, you need to take into account a number of parameters:

• The size of the bathroom and toilet - can be significantly saved if you install a new pipeline immediately in 2 rooms;
• Location of plumbing - bath, toilet, washbasin and washing machine (if it is in the bathroom);
• Turns and bends - from their quantity the number of clamps, connecting муфты, angular elements etc. is defined;
• The nature of the pipeline: so, for hot water it is better to choose a plastic or copper pipe, and for a cold one - plastic.

All of the above parameters are recommended to be transferred to the drawing and follow the scale.

Dismantling of the old structure

Replacement of pipes in the toilet and in the bathroom begins with the dismantling of the old structure. This requires a preliminary shutdown of the water near the risers, through which hot and cold water enters. If it is planned to replace the riser pipes, turn off the water supply in the basement. Some conditions must be satisfied:

• Obtaining an agreement on the work of the organization that provides maintenance of intra-house communications;
• Early warning of neighbors that the pipeline will be replaced; At the same time, the date and time of the work should be clarified;
• Replace the pipes and restore the water supply in time.

The introduction of a new riser pipe into the system is desirable to be carried out from the apartments of neighbors living on the floor above and below, so if there is such an opportunity, it is better to discuss this point in advance. By the way, the option is beneficial for both sides: the person who is carrying out the replacement of the riser can safely continue finishing, it will not flow exactly, and it will be much easier for neighbors to perform future repairs.

Overview of outdoor sewer pipes

Reliable operation and long service life of the sewerage network is ensured by the timely replacement of pipes in the bathroom and toilet. The review of the modern market of the sewerage equipment allows to allocate following kinds of suitable materials:

1. Asbestos-cement pipes. Portland cement and asbestos fiber are used for their manufacture. They are characterized by high throughput and a smooth internal surface. Slight weight provides easy transport and stowage.
2. Ceramic pipes are very strong and durable material, resistant to aggressive environmental influences and corrosion.
3. Cast-iron pipes are a classic variant of the arrangement of an external sewerage network. They are distinguished by such positive qualities as reliability and resistance to chemical and mechanical effects.
4. Plastic pipes are the most commonly used material. Such a sewer pipe is inexpensive, easy to handle and pack, resistant to various aggressive influences and durable.

Sequence of installation

Replacing the sewer pipes in the bathroom and toilet with your own hands is a fairly simple process, especially if there is little experience or there is an opportunity to attract a good helper to work.

Sequence of open installation:

1. Schematic plan - this is where the replacement of pipes in the toilet and in the bathroom should begin. Installation will not be effective if you do not previously calculate the necessary materials and docking elements.
2. The cut of the old metal pipeline can be done with a grinder, a perforator or a hammer with a chisel. Safety is above all, so you need to take care of the presence of a mask and a respirator, as this is a fairly dusty process.
3. The next important point is the withdrawal of the sewer pipe by means of taps and joints. This stage of work requires the presence of a special welding machine, since otherwise it will not work to solder the pipes. Before making the final connection, it is recommended to check the correct location of the pipes. After the pipes have been welded, they can be connected to the bathroom faucet.

In the presence of a combined room, the replacement of pipes in the toilet and in the bathroom should be done in parallel with the installation of an additional valve to shut off the water supply to the drain tank, which is very convenient if, for example, you need to replace the hose.

The final stage is the installation of the mixer. On this, the replacement of pipes in the toilet and in the bathroom is considered finished.

After that, you only need to hide the pipes, which is done both for the sake of aesthetics, and for safety.

Advantages of plastic sewer pipes

Creation of a quality sewage system ensures the replacement of pipes in the toilet and in the bathroom. Types of pipes made of plastic: polyvinyl chloride (PVC), polyethylene, which characterizes high density (PVP) and polypropylene (PP) - an excellent option for these works.

This material is suitable for both internal and external sewerage. Comparison with cast-iron and steel pipes shows that a smoother surface is prone to plastic, excluding the possibility of clogging. A small mass facilitates the transportation and installation of pipes, and also does not require additional equipment and a special solution for embedding. Sealed connection guarantees a long service life.

PVC pipes

Replacement of pipes in the toilet and bathroom - a simple process, but requiring the following basic requirements for the sanitary construction:

• High strength;
• Resistance to mechanical stress;
• The ability to withstand runoff temperatures of up to 70 degrees.

All the above conditions correspond to pipes made of polyvinyl chloride.

Among the disadvantages are exposure to chemicals and even aggressive household detergents, which damages the walls and contributes to the formation of plaque, which in time can turn into serious clogging.

Polypropylene pipes

Sewer polyethylene pipes can be used for the work on the replacement of internal and external sewerage. Special fittings are used for the connection.

This material is not afraid of mechanical influence and high temperature - up to 100 degrees, is resistant to various acids and alkalis. Ideal for draining a washing machine or dishwasher. Polypropylene pipes can be used for the organization of sewerage in an apartment or a house, as well as at a public catering establishment, in a dry cleaning, school or medical facility.
