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-assembly.

Materials and tools needed to replace pipes

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

  • grinders with an installed disc for metal - with its help, old pipes and fasteners are cut;
  • a hand-held die cutter, the diameter of which is exactly the same as the size of the riser (about 1 inch) or any other tool that can thread a metal pipe in an apartment located on the top or bottom floor;
  • perforator needed to drill holes for fasteners or, if necessary, lay a pipe through the wall;
  • electric soldering iron complete with nozzles and pipe cutter;
  • tape measure, chisel, hammer, marker and screwdriver.

Replacement of sewer pipes in the bathroom andthe 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, fasteners, technical vaseline, fumlents, 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, a number of parameters must be taken into account:

  • the size of the bathroom and toilet - you can save a lot if you install a new pipeline in 2 rooms at once;
  • location of plumbing - bath, toilet, washbasin and washing machine (if available in the bathroom);
  • turns and bends - the number of clamps, couplings, corner elements, etc. is determined from their number;
  • character of the pipeline: for example, for hot water it is better to choose a metal-plastic or copper pipe, and for cold water - plastic.

It is recommended to transfer all of the above parameters to the drawing and observe the scale.

Dismantling of the old structure

Replacing 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 flows. If it is planned to replace the riser pipes, then the water supply should be turned off in the basement. In doing so, someconditions:

  • obtaining approval for work from an organization providing maintenance of intra-house communications;
  • early notification of neighbors 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.

It is desirable to introduce a new riser pipe into the system from the apartments of neighbors living on the floor above and below, so if possible, it is better to discuss this point in advance. By the way, the option is beneficial for both parties: the person replacing the riser can safely continue finishing, nothing will leak from him, and it will be much easier for the neighbors to carry out future repairs.

Overview of pipes for external sewerage

Reliable operation and long service life of the sewer network is ensured by the timely replacement of pipes in the bathroom and toilet. An overview of the current market for sewer equipment allows us to distinguish 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. Light weight for easy transport and stacking.
  2. Ceramic pipes are very strong and durable material, resistant to aggressive environmental influences and corrosion.
  3. Cast iron pipes - a classic arrangementexternal 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

Replacing sewer pipes in the bathroom and toilet with your own hands is a fairly simple process, especially if you have little experience or you can get a good assistant to work.

Open Mount Sequence:

  1. Schematic plan - this is where the replacement of pipes in the toilet and in the bathroom should begin. The installation will not be effective if you do not first calculate the necessary materials and docking elements.
  2. The cut of the old metal pipeline can be done with a grinder, a puncher or a hammer with a chisel. Safety is paramount, so you need to take care of the presence of a mask and a respirator, as this is quite a dusty process.
  3. The next important point is the withdrawal of the sewer pipe through bends and connections. This stage of work requires a special welding machine, otherwise it will not be possible to solder the pipes. Before making the final connection, it is recommended to check the correct position of the pipes. After the pipes are soldered, you can connect them withbath faucet.

If there is a combined room, the replacement of pipes in the toilet and in the bathroom should be carried out 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 over.

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

Advantages of plastic sewer pipes

The creation of a quality sewerage 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 excellent options for these jobs.

This material is suitable for both internal and external sewage. A comparison with cast iron and steel pipes shows that plastic pipes have a smoother surface, eliminating the possibility of clogging. The light weight facilitates the transportation and installation of pipes, and does not require additional equipment and a special mortar for sealing. Sealed connection guarantees a long service life.

PVC pipes

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

  • high strength;
  • resistance to mechanical stress;
  • capable of withstanding runoff temperatures up to 70 degrees.

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

Among the disadvantages are exposure to chemicals and even aggressive household detergents, which damage the walls and contribute to the formation of 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. Special fittings are used for connection.

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