Replacement of pipes in the bathroom with your own hands: features of sewerage installation

People need to replace pipes in the bathroom for two reasons. This can be a planned repair or emergency replacement. Of course, the first option is the best, because you can prepare for it, buy all the materials and plan the work plan. It is necessary to approach the question of pipe replacement in a balanced way, especially if it occurs by oneself. Erroneous actions or negligence can lead to bad consequences. Immediately before installation, you need to select suitable pipes, dismantle the old ones and prepare the room.

The main task of the sewer is to feed fresh and drainage water from a sink, a bathtub and other appliances. Sewerage in an apartment or a private house is a rather complex and often heavily ramified system, which includes: an

• riser with a spider for pipes of different diameters;
• is the main highway through which water flows from the house;
• pipe going to the bathroom( diameter 50 mm);
• pipe leading to the kitchen;
• additional branching.

Today you can buy different types of pipes, differing in the material of manufacture, characteristics, price, practicality and so on. All of them can be combined into the following groups:

Among the metal pipes, the most common are cast iron. They are as durable and durable as possible, but can be corroded, quickly contaminated and very heavy. As a rule, they are installed in old houses and apartments built 10 or more years ago. Widely used and steel products. But it is quite difficult to mount such pipes, because they need a welding machine for their connection, and for cutting - a Bulgarian. You can do without welding, for this you need to cut the ends of the connecting pipes thread. This is also done to connect the crane. Due to corrosion, the pipes must be constantly painted.

They replaced the metal pipes. Their interior is made of aluminum, and the outer one is made of polyethylene. They do not lend themselves to corrosion, they are pretty strong and reliable. These pipes are quite easy to bend without the need for heating on welding. You can cut them with a simple metal hacksaw. After stripping with sandpaper, the ends of the pipe are joined by special fittings.

These are very popular products, mainly used in apartments. They differ in light weight, aesthetic appearance, resistance to rust, decent strength and ease of installation. In constant care and painting, they do not need. Polypropylene pipes are easy to bend, they can be cut with a simple knife, and they are connected by cold welding or a special soldering iron, for which you do not need special skills. The low price and variety of such pipes contribute to their high popularity.

Pipe placement places are placed before installation. When installing the drain, the angle of inclination necessary for better outflow of water through the pipes and the absence of clogs is taken into account. It is very easy to calculate it:

1. For pipes with a diameter of 80-100 mm, the angle should be 2 percent.
2. For pipes 40-50 mm - 3 percent.

In practice, everything is very simple. For example, if a pipe with a diameter of 50 mm is used, then on every meter of its length the slope should be 3 cm.

For dismantling old pipes, a hammer with a chisel may suffice, but sometimes it can not do without a bolgar or perforator. The following work order should be adhered to:

1. Water is turned off in the whole house or apartment. Then dismantle the bushings.
2. The old entry faucets are screwed up, the pipes are cut off and new ones are screwed.
3. The inlet valves are closed, after which water can be turned on.
4. From old pipes, drain the water as much as possible, disconnect faucets and other appliances.
5. Pipes are disconnected from the sewer and can be safely cut.

It is impossible to remove steel dowels from brick or concrete walls, so they are simply cut off by a Bulgarian. New pipes should be laid as close to the floor as possible, so that the walls do not shroud.

As already mentioned, it is difficult to replace tubes in the bathroom yourself, but it is easy. It all depends on the scope of the proposed work, the availability of the necessary tools and skills to work with them.

The pipe installation process may differ in different conditions, but the standard steps are as follows:

1. If all preparatory work and dismantling are completed, a filter is installed after the shut-off valve and counter. The same is done with hot water.
2. The counters are placed so that the special arrows on them show the direction of movement of the water.
3. The installation of pipes is then carried out directly. This process depends on their kind. Since some of the best quality are polypropylene pipes, we will consider the installation process using their example. Cutting the pipes into separate fragments, they are connected in the right places, glued or welded with a soldering iron.
4. For connections, various adapters, angles, elbows and special couplings are available, which allow connecting pipes from different metals.
5. The time for heating the pipe and fitting with a soldering iron depends on their diameter. You can find out about this from the instructions to this tool. The plastic dries and hardens in less than a minute.
6. As hot water slightly expands polypropylene pipes, they are not allowed to be rigidly fixed to the wall. It should be sliding, which can be achieved with plastic clips, fastened to the wall by dowels.
7. Specialists recommend to install separate ball valves for a washing machine, boiler, shower and other appliances in the bathroom and in the kitchen. They cover the water only to a certain object, so it does not need to be switched off throughout the house when repairing one technique.
8. All threaded connections must be securely sealed.
