How to change pipes with your own hands

Through pipeline systems, several cubes of water passes daily. Pipes in the bathroom and the toilet come into disrepair and need to be replaced. It is not difficult to change the pipes in the apartment with your own hands. Anyone who knows how to spin the nut with a confusing key is forces.

After making the decision to replace the internal wiring of pipes throughout the apartment, pay attention to the state of risers. It may take not only the replacement of pipes in the toilet and the bathroom, but it is necessary to change the riser.

Select pipes to replace the internal wiring in the apartment

1. Steel pipes previously widely used for mounting internal wiring. Steel pipe withstands high temperature and pressure. But this arrangement has several drawbacks. The steel is subject to corrosion, condensation drops, and the inner side of rust and lime on the outer surface. There are difficulties and the installation of metal pipes. It requires skills in tapping or the ability to make welded, sealed seams. An important disadvantage of steel tubing - conductivity.
2. Metal pipes are much lighter than metal pipes and easier to install. They are easy to bend his arms with a special steel springs. It is essential for the construction of internal wiring of pipes in the bathroom or toilet in remote places. Plastic pipes have a high capacity without lime or rust. For installation required fittings, which are collected using an adjustable wrench. Pipes easily withstand hammering and divided into two types: hot and cold water. The warranty period of 35 years.
3. Plastic water pipes have all of these positive qualities. For the installation of pipes need special glue or soldering and fittings. Such a system is durable, has a low weight and impervious to corrosion. Her fearless can be immured in a wall or hide under the floor. Plastic tubes differ by types:

• polyethylene tube - connection at joints made soldering. For pipe for hot water acquired XLPE tubes;
• pVC pipe - not only used for the internal wiring of water, but also for heating. A compound pipe with threaded fittings made using special glue;
• polypropylene tubes are most often used for the replacement of pipes in the apartment. The low price and the universal characteristics for cold and hot water pipes make this type most demanded. Compound at the joints is done by soldering.

Tools for the replacement of pipes in the bathroom and toilet

• Turboshlifovalnaya machine (Bulgarian) with a cutting disc for metal useful for dismantling old metal pipes.
• Tubular electric soldering iron or a special adhesive for plastic pipes depending on installation method.
• Cutter for plastic pipes and scan (for pipes of metal).
• Adjustable pipe wrenches №1 and №2, Swedish-key, a set of open-end spanners from 18 to 36 mm.
• Drill with a percussion mechanism and drill with a titanium head.

For pipes of metal required for threading chaser and vice.

Materials required for work

• For inner wiring, pipes are used with a diameter ½ and ¾ inch steel or 16 - 20 mm plastic.
• Fittings in the required quantity (end, angular and intermediate tees).
• Cutting valves for each layout.
• Linen pala (winding).
• Pipe mounts - 1 pcs 0.5 meters.
• Technical Vaseline for threaded compounds.

Dismantling of the old pipeline in the bathroom and toilet

The first thing overlaps the water pressure in the riser. The cutting valve is usually located in the basement. Make sure that the cutting valve reliably holds water, and it is missing in the internal wiring system.

1. All connected objects are disconnected: bathroom faucets, toilet tank, washbasin, etc. Pipe key number 2 is clamping a dismantled pipe. The key is taken into the left hand, and the key clamps are directed towards the wall. The second key number 1 takes the coupling, the cheeks are directed in the opposite direction. Holding the pipe with a second key with a second key with an effort, but without jerks, unplug the coupling.
2. In those places where the compounds finally threw or rotten, and to promote them is impossible, the pipes are cut into a turbine with a cutting disk for metal. When working, keep care and protective equipment. Especially take care, do not work without protective glasses.

If the wiring is made without replacing a common riser, then a new thread is cut on the releases, and stop valve cranes are installed. By closing the shut-off cranes, you can open water in the riser and continue installing the inner wiring.

The procedure for mounting the internal wiring of the water supply

Walls are prepared and the layout of the future runway route is made. For the hidden installation of the wiring in the walls, the grooves are strobalized, and for the outer - the holes under the dowel are drilled in the mounting places.

1. Installing the inner wiring pipes begins with connecting the filter of coarse cleaning after the cutting valve on the inputs of hot and cold water. There is an arrow on the filter housing indicating the direction of water movement. A pinch of linen packley is taken, small litter is combed with fingers and twisted into a thin twine of about 1 mm thick.
2. From the edge of the thread clockwise, the packle is tightly wounds to the base of the release. A little technical vaseline is applied to the passage and smeared at the beginning of the threaded connection. The filter is connected to the release and twisted. First manually, and then tightened with the key. For a high-quality connection, it is necessary to make at least 4.5 - 5.5 full speed of the part of the part.
3. After the coarse cleaning filter, a waterline meter is installed and a check valve. All parts are equipped with indicable arrow directions of water flow, and the meter itself is fastened with precipitated nuts (American) with rubber gaskets. When installing the meter to enter hot water, the gaskets change to paronites. The meter is installed immediately after entering in an accessible place. The direction and position of the dial does not matter.
4. A plastic pipe is installed from the counter to the nearest plumbing object. The cutter for plastic pipes is cut off the blank in size. On the one hand, the end fitting is mounted, and on the other passing a tee with a threaded release. The compound is performed using a soldering iron or glue, depending on the type of plastic pipes. There are served and end knees on sale with an angle of 45 ° and 90 °.
5. A cutting ball valve is installed on each plumbing object at the connection site. Thus, in the case of a malfunction for repair, it will not be necessary to overlap water in the entire apartment, it is enough to disable only one object. From the release of the cutting crane, connective hoses for mixers, a toilet tank, etc. are installed.

Checking the internal wiring after replacing pipes

Seamlessly, starting with a weak pressure, water is supplied to the internal layout system. After waiting 10 minutes, all joints and places of threaded connections are checked. When detecting leaks, it is eliminated. In the threaded connections, it is enough to tighten or repack the node. The leaks on adhesive or steel connections are eliminated by a complete replacement of the node.
