Installing a water outlet in the bathroom

When people plan to install a faucet in the bathroom or a washing machine, they need to install water outlets. They are also needed for dishwashers. The installation of water outlets must be carried out at the initial stage of the repair, when the rough work has not yet been completed. To do this, you need to carry out polypropylene pipes, the diameter of which should not be more than 20 millimeters. The installation of a water outlet in the bathroom takes place after the installation of a pipe with internal reinforcement.

What materials will be required for the job?

Installation of water sockets requires a careful approach to the materials from which they are made. They use different fittings. They are chosen depending on where the water outlets will be installed. It is important to consider the connected consumer. The following fittings can be used:

  1. Combination angle elbow, the internal thread of whichequals one second of an inch. The knee has a 90 degree angle. It has an outlet for a polypropylene pipe with a diameter of 20 millimeters. Connections of this type are often used for hidden installation of pipelines. They are laid directly into the pipe.
  2. Combined elbow PP, wall-mounted. It is marked D 201x1/2 BP. Fittings of this type are used for surface mounting on the wall. They are suitable for work in a finished wooden house. This fitting is used when installing water sockets inside walls. They have extra fasteners. The outlet area is larger than in the previous version. It is securely attached to the wall.
  3. Angled knee on bar (included). This type of fitting contains two combined elbows PP, marked D201x/2 BP. They are interconnected with a special bar. The distance between them is standard, like any other wall faucets. Installing water outlets under the mixer has its own specific features. They are also installed in the shower.

At the welding stage, it is required to weld two pipes at the same time. It is difficult for a craftsman to work with two pipes at once.

What materials are they made of?

For the production of water outlets, stainless steel is most often used. They can be made from galvanized iron. Often found in brass and bronze. Some manufacturers produce PVC and polypropylene elements.

Where are they most often installed?

You can't do without water sockets in the following rooms:

  1. In the bathroom. This usually requiresat least 4 water outlets.
  2. In the toilet. They put 1 water outlet, which is needed in order to bring the pipe to flush. If the bathroom is combined with a bath, then you will need to install 5-6 elements
  3. In the kitchen.

Which connections are suitable for installation under a heated towel rail?

Installation of water outlets under the heated towel rail requires the presence of corner joints. The fitting diameter can be ¾ or 1 inch. It all depends on the connection configuration. Corner joints use internal threads. It is universal and suitable for mounting various mixers.

Where is the external thread installed and where is the internal one?

To install a wall-mounted faucet in the bathroom, you need eccentrics. They are available with external thread. If you want to connect a standard mixer, then take an eyeliner with an external thread. It is ½ inch. For European faucets, an adapter nipple is required. This type of faucet comes with a 3/8 inch thread. The nipple is taken with a thread ½.

How is markup done?

At the initial stage of work, you need to calculate what the height of the installation of water outlets will be. Pipes in strobes are considered with a margin, at the end of work they are cut along the horizontal marking line. When the welding stage is completed and the pipes are placed in a niche, you need to draw a planar marking on the wall. It must be part of the project. Vertical axes pass through the centers of the rosettes. The distance between them should be at least 150 millimeters. This markup is used forinstalling a wall faucet. For faucet to sink distance may vary.

After a person has drawn a vertical markup, you need to carefully place the pipes along it. The next step is to apply vertical markings. The level height is specified in the project.

It is important not to forget to mark the pipes horizontally. The error is 15 millimeters. You should stock up on scissors for cutting polypropylene pipes and make cuts according to the markings. When installing water sockets, the dimensions of the pipes must be observed. After that, you can start chasing the wall to the desired depth.

How to properly prepare pipes for soldering with sockets?

An important step in the installation of water sockets is the fitting of couplings. It should be checked that the threaded holes correspond to the specified level. The error should not be more than five millimeters.

There are times when one pipe ends up being shorter than the other. In this case, it should be increased. You will need a part of a polypropylene pipe, the diameter of which is 20 millimeters. You should take the length with a margin of five centimeters. You will also need a special polypropylene sleeve. This connection is highly durable. If it is installed correctly, it will be no less durable than a one-piece structure. The connection can be mounted inside the wall.

The stage of soldering pipes before installing water sockets

To solder polypropylene pipes, you will needspecial soldering iron. Along with it, various nozzles should be attached that fit different pipe diameters.

The end of the pipe is installed in one of the nozzles of the soldering iron, the other nozzle is installed in the coupling. It is important to avoid overheating during operation. At the soldering stage, a backlash appears. Because of this, when cooling, a void forms in the joint.

It must be taken into account that the water outlet should be correctly placed in height, and also observe the angle of the axis of rotation. An angle of 90 degrees must be maintained to the plane of the wall.

After fixing the coupling on the pipe, you need to wait a minute. After that, the connection can not be kept. Do not use the water supply while the connection is still hot. If it has not cooled down completely, then the water pressure can damage the solder joint. Care must be taken to ensure that the plumbing is not used until the connections have cooled.

How does wall thickness affect the installation of water outlets?

An important issue is the installation depth of water outlets. Pipelines must be securely fixed in relation to the thickness of the walls. Much depends on the decoration of the walls, what materials are used for this. When installing a water outlet, its plane must be identical to the plane of the wall. Options are possible when sockets are "drowned" in the wall. In this case, the depth should not be more than five millimeters.

When homeowners want to paint the wall, or it has already been plastered, the coupling should be installed in the plane of the wall. When is the installation of water outlets required?under the tile, then you need to look at the thickness of the wall and the thickness of the tile adhesive layer. With the work of such a plan, you can handle it yourself. All recommendations should be followed, and then you will not have to call the wizard.

You can not install water sockets with a ledge from the outer wall, otherwise it will be problematic to install a wall-mounted faucet. With this installation, the reflectors will not tightly cover the eccentrics. As a result, a gap will appear. It will look unaesthetic.

How to test connections?

After fixing the pipes and couplings relative to the walls, put plugs on the threaded connections. After that, you need to start the water supply. After fifteen minutes, you can check the pipes for leaks. You should pay attention to the places where the soldering was carried out.

How can I seal the seams?

If a leak could not be detected when the water was turned on, then you can proceed to the stage of sealing the seams. You will need mortar to work. You can use plaster. Tiles can be laid on a flat surface.


So, we found out how the installation of water outlets is performed. As you can see, this operation can be carried out independently. The main thing is to follow the instructions correctly.
