Many people prefer to do repairs with their own hands, to save on hiring specialists and do everything the way they planned. Therefore this article will be interesting to house masters.

Preliminary stage

Preliminary stage

To replace the toilet you need these tools and accessories:

  • Water hose to connect the water supply;
  • Corrugated pipe (or corrugation) for connecting the toilet to the sewer;
  • A toilet bowl with a flush cistern (as a rule, fixtures are supplied with fixtures);
  • Spanners, hammer drill, hammer and chisel;
  • Silicone glue.

Before starting the installation, it is necessary to dismantle the old toilet. Previously, cement was used most often to fix the toilet bowl. So you have to use a chisel and a hammer. Before this, it is necessary to disconnect the plumbing from the communications: first you need to turn off the water and disconnect the pipe, going to the cistern, then gently disconnect the toilet from the sewer. In no case do not strike the strut with a hammer. In old houses, it is most often made of cast iron. This is a very fragile material. Also try to keep the garbage from getting into the riser, otherwise you will have to clean the blockages.

Shut off water supply to tank

Then you need to align the space for installation of a new toilet. Often, old plumbing is installed on wooden bars mounted in the floor. If you remove them carefully fails, you can leave. To level the base is used sand-cement mortar or tile glue. It is necessary to carry out a fitting of the stability of the new toilet in its place, in order to avoid further difficulties during installation.

Features of the location of the drain

Features of the location of the drain

Manufacturers produce three types of toilets, differing in the location of the drain. Drain pipe can be located:

  • parallel to the floor;
  • at an angle;
  • abut the floor itself.

Choosing a model, you need to consider the location of the inlet sewer pipe. Models with the direction of the drain pipe directly to the floor are rare. These types of toilet bowls are installed on the condition that the pipe is on the floor. But this option is used only in private homes.

The most common type is a toilet with an inclined arrangement of the drain pipe. At its connection it is convenient to use a corrugation.

Corrugation allows you to connect the toilet to the sewer, even if the drain pipe is not located with the pipe in the same vertical plane.

Progress

Progress

If there is a complete repair of the toilet, then the installation of the toilet should be dealt with after all the work is done so that the installed plumbing does not interfere.

The progress of the installation of the toilet:

  1. Making the markup. Place the toilet on the intended installation site. Check that it is convenient to use. The distance from the drain of the toilet to the mouth of the sewer should be in the range of 10 to 20 cm. So, it will be convenient for you to connect using corrugations. It is permissible that the neck and drain of the toilet bowl be located at a slight angle. The design of the corrugations allows you to connect in this case.
  2. After choosing the place we make markings for fastening. To do this, through the holes in the base of the toilet do marks. Then, using a perforator, we make holes in the floor to them at a depth corresponding to the fixing devices (as a rule, a plastic dowel and a self-tapping screw are used for this purpose).
  3. Install the toilet and fix it. The plumbing device should stand firmly and not stagger. Glue the toilet and the floor glue silicone gel (sealant). This is necessary to prevent water and dust from entering the gap.
  4. Connect the toilet bowl drain to the sewer pipe. For this is used corrugation. To improve the tightness of the joints are also lubricated with silicone gel.
  5. Next, you need to install a drain tank and connect it to the water supply. To do this, use a flexible hose in a metal sheath. Such a connection is better than using pipes. In the event of a breakdown, you can easily disconnect the tank.

The location of the toilet

After all the work is done, the tap is opened and a control drain is made. Observe the behavior of all the joints so as not to leak. Remember that even small drops may eventually appear on the ceiling of the neighbors below, if you live in an apartment building.
