Replacing pipes in the toilet and in the bathroom. Brief instruction

Nowadays, the old metal pipeline is often replaced by a new metal-plastic or plastic one. This option has many advantages, the main of which is the possibility of self-assembly.

Materials and tools needed to replace pipes

Replacing pipes in the toilet and bathroom requires the following tools:

• grinders with an installed metal disc - with its help, old pipes and fasteners are cut;
• a manual screwdriver whose diameter completely matches the size of the riser (about 1 inch) or any other tool that can be used to thread a metal pipe in an apartment located on the upper or lower floor;
• a perforator necessary to drill holes for fasteners or, if necessary, lay a pipe through the wall;
• an electric soldering iron complete with nozzles and a pipe cutter;
• tape measure, chisels, hammer, marker and screwdriver.

Replacing sewer pipes in a bathroom and toilet is impossible without two adapters connecting a metal pipe and a plastic one, 1/2 inch polypropylene pipes, as well as tees, splitters, fittings , self-tapping screws, mounts, petroleum jelly, fumlenta, etc.

Preparatory moments

If the owner of the apartment is not a professional repair worker or plumber, then 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 - you can save significantly if you install a new pipeline in 2 rooms at once;
• Plumbing location - bathtub, toilet bowl, washbasin and washing machine (if available in the bathroom);
• turns and bends - from their number the number of clamps, couplings, angular elements, etc. is determined;
• nature of the pipeline: for hot water, it is better to choose a metal-plastic or copper pipe, and for cold water - a plastic one.

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

Dismantling the old structure

Replacing pipes in the toilet and in the bathroom begins with the dismantling of the old design. This requires a preliminary shutdown of water near the risers, which receives hot and cold water. If it is also planned to replace the riser pipes, then the water supply should be turned off in the basement. In this case, some conditions must be met:

• obtaining approval for work from an organization that provides intra-house communications services;
• Advising neighbors in advance that the pipeline will be replaced; at the same time, the date and time of the work should be clarified;
• replace pipes and restore water supply in time.

The introduction of a new riser pipe into the system is preferably carried out from the apartments of neighbors living a 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 parties: the person who is replacing the riser can safely continue the finish, it will certainly not leak, and it will be much easier for the neighbors to carry out future repairs.

Overview of pipes for outdoor sewage

Reliable operation and long service life of the sewer network is ensured by the timely replacement of pipes in the bathroom and toilet. A review of the modern sewer equipment market allows us to identify the following types of suitable materials:

1. Asbestos-cement pipes. For their manufacture, Portland cement and asbestos fiber are used. They are characterized by high throughput and a smooth inner surface. Low weight for easy transport and installation.
2. Ceramic pipes are a very strong and durable material, resistant to aggressive environmental influences and corrosion.
3. Cast iron pipes - a classic version of the arrangement of an external sewer network. They are distinguished by such positive qualities as reliability and resistance to chemical and mechanical influences.
4. Plastic pipes are the most commonly used material today. Such a sewer pipe is inexpensive, easy to process and install, resistant to various kinds of aggressive influence and durable.

Installation sequence

Do-it-yourself replacement of sewer pipes in the bathroom and toilet is a fairly simple process, especially if there is little experience or it is possible to attract a good assistant to work.

Open Mount Sequence:

1. A 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 first calculate the necessary materials and connecting elements.
2. The cut of the old metal pipeline can be carried out using a grinder, a puncher 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, since this is a fairly dusty process.
3. The next important point is the withdrawal of the sewer pipe through outlets and connections. This stage of work requires 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 placement of the pipes. After the pipes are welded, you can connect them to the bathtub mixer.

If there is a combined room, the pipes in the toilet and in the bathroom should be replaced 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. At this, the replacement of pipes in the toilet and in the bathroom is considered complete.

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

The advantages of plastic sewer pipes

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

Such material is suitable for both indoor and outdoor sewers. Comparison with cast iron and steel pipes shows that plastic has a smoother surface, eliminating the possibility of clogging. The light weight facilitates the transportation and installation of pipes, and also does not require additional equipment and special mortar for sealing. Hermetic connection guarantees a long service life.

Pvc pipe

Replacing pipes in the toilet and in the bathroom is a simple process, but it requires taking into account the following basic requirements for a sanitary design:

• high strength;
• resistance to mechanical stress;
• ability to withstand stock temperatures up to 70 degrees.

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

Among the shortcomings are exposure to chemicals and even aggressive household detergents, which damages the walls and contributes to plaque, which over time can turn into a serious blockage.

Polypropylene pipes

Sewer polyethylene pipes can be used for work on the replacement of internal and external sewers. For the connection, special fittings are used.

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