How to change the pipe with his hands

A pipeline system daily runs several cubic meters of water.The pipes in the bathroom and toilet are deteriorating and in need of replacement.Change the pipe in the apartment with his hands is not difficult.Any person who knows how to tighten the nut wrench can do it.

deciding to replace the internal pipework throughout the apartment, pay attention to the condition of the risers.You may need not only the replacement of pipes in the toilet and bathroom, but there is a need to change the riser.

Choice pipes to replace the internal wiring in the apartment

1. steel pipes previously widely used for the installation of internal wiring.The steel pipe can withstand high temperatures and pressures.But this arrangement has several disadvantages.The steel is subject to corrosion, condensation drops, and the inner side of rust and lime on the outer surface.There are difficulties in installing and metal pipes.It requires skills in tapping or the ability to make welded hermetic joints.An important disadvantage of steel tubing - conductivity.
2. Metal pipes are much lighter than metal pipes and easier to install.They are easy to stick to your hands using special steel springs.It is essential for the construction of the internal wiring of pipes in the bathroom or toilet in remote places.Plastic pipes have a high capacity, no lime and rust.To install the required fittings, which are collected using an adjustable wrench.The pipes can easily withstand hammering and are divided into two types: hot and cold water.The warranty period of 35 years.
3. Plastic water pipes are 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 hidden under the floor.Plastic pipes are distinguished by type:

• polyethylene pipes - the connection is made at the junction of a soldering iron.For the pipeline for hot water pipes purchased from cross-linked polyethylene;
• PVC pipes - are not only used for the internal wiring of the water supply, but also for heating.Connection pipes with threaded fittings are manufactured using a special adhesive;
• polypropylene tubes are most often used to replace the pipes in the apartment.The low price and versatile features for cold and hot water pipes do this kind of the most in demand.The connection at the joints is performed by soldering.

Tools for the replacement of pipes in the bathroom and toilet

• Turboshlifovalnaya machine (Bulgarian) with a cutting disc for metal useful for the dismantling of old pipes of metal.
• Pipe electric soldering iron or a special adhesive for plastic pipes depending on the installation method.
• Cutter for plastic pipes and Scan (for pipes made of metal).
• Adjustable pipe wrenches №1 and №2, Swedish key set carob keys from 18 to 36 mm.
• drill with the hammer mechanism and the drill with a titanium head.

For pipes of metal required chaser for threading and vice.

necessary materials for

• used pipe diameter ½ and ¾-inch steel or 16 For internal wiring - 20 mm plastic.
• fitting in the required amount (end, corner and intermediate tees).
• shut-off valve on every issue wiring.
• Flax tow (preroll).
• Pipe mount - 1 piece 0.5 meters.
• petroleum jelly for threaded connections.

Dismantling of old pipe in the bathroom and toilet

First overlaps the water pressure in the riser.Isolating valve, usually located in the cellar.Make sure that the shut-off valve is securely holds the water and it is not in the system of internal wiring.

1. disconnect all connected objects: taps in the bathroom, the toilet tank, sink, etc.Tong №2 clamped detachable tube.The key is taken into the left hand and the key clamping cheeks are directed towards the wall.The second key №1 taken coupling, cheeks are directed in the opposite direction.Holding a key conduit second key firmly, but without jerks loosen the coupling.
2. In those places where the connection finally thickets or rotten, and they can not roll out, cut the pipe to the turbine disk for metal cutting.When working, be careful and protective equipment.Especially take care of the eyes, do not work without protective goggles.

If wiring is done without changing the overall riser, then cut releases a new thread, and set the shut-off valves.After closing the shut-off valves can be open water in the riser and continue installation of the internal wiring.

Mounting internal wiring aqueduct

prepare the wall and is counting on the future route running water.For flush-mounted wiring in the walls of the groove Stroebe and outdoor - at fixing drilled holes for dowels.

1. Pipe installation begins with internal wiring connecting the strainer after the shut-off valve on the inputs of hot and cold water.In the filter housing has an arrow indicating the direction of water movement.Take a pinch of flax tow, combed his fingers dirty shirt and twisted into a thin twine about 1 mm thick.
2. From the edge of the thread clockwise tow tightly wound before the release of the base.In the tow is applied little smear of petroleum jelly and the beginning of the threaded connection.The filter is connected with the release and twists.At first by hand and then tightened the key.For high-quality connections necessary to make at least 4.5 - 5.5 complete rotations housing parts.
3. After the coarse filter is installed water meters and a check valve.All items are supplied with the navigation controls water flow direction, and the counter is secured with union nuts (Americans) with rubber gaskets.When installing the meter to enter the hot water laying on paronitovye change.The counter is set immediately after input in an accessible place.The direction and position of the dial does not matter.
4. from the meter to the nearest sanitary facility installed plastic pipe.Cutter for plastic pipes cut workpiece size.On one side of the end fitting is attached, and on the other with a threaded tee passage outlet.The connection is made by means of soldering or adhesive, depending on the type of plastic pipes.On sale there are checkpoints and end with a knee angle of 45 ° and 90 °.
5. Each sanitary facility on the connection is established cut-off ball valve.Thus, in case of failure need not overlap the water across the flat, one need only disconnect facility for repair.From the release shut-off valve installed connecting hoses to faucets, toilet tank, etc.

Check internal wiring after replacing pipes

smoothly, starting with a weak pressure, water is supplied to the internal wiring system.After waiting 10 minutes, checked all the joints and places of threaded connections.If a leak is detected it eliminates.In threaded joints enough to tighten or repack the unit.Leaks in the adhesive or solder joints are eliminated a complete replacement unit.
