Among the most common metal pipes - cast iron.They most robust and durable, but corrode rapidly polluted 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 undertake installation of such pipes is difficult, because of their connections need welding machine and cutting - Bulgarian. can do without welding, it needs to be cut into the ends of the pipe thread.This is being done to connect the crane.Due to the corrosion of the pipe need to constantly paint.

This is a very popular product, used mainly in homes. They differ light weight, aesthetic appearance, resistance to rust, a decent strength and ease of installation.The constant care and they do not need painting. pipes Polypropylene is easy to bend, cut them with a knife can be simple, but they are joined by cold welding or special soldering iron, to work with who do not need special skills.The low price and variety of such pipes contribute to their high popularity.

The training includes calculation of the need for pipes, materials and special tools for their purchase.In addition to pipes, need a variety of tees, reducers, seals, tool - Bulgarian, welding, adjustable wrench, a drill, a knife, a hammer and other (depending on the pipe material).To properly calculate the need for materials, it is better to draw a sewer plan.

applied before installing the placement of pipes.When installing the drainage angle is taken into account, necessary for better drainage of water through the pipes and lack of obstructions. Calculate it very simply:

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

In practice, it is very simple.For example, if a pipe diameter of 50 mm, then each meter of its length, the slope should be 3 cm.

Dismantling of old pipes

To remove the old pipes can last a hammer with a chisel, but sometimes notdo without grinders or punch. You must adhere to the following order of business:

  1. In the house or flat water is turned off.Then carried out the dismantling of inputs.
  2. Next screwed outdated input taps, cut the pipe and the new bolted.
  3. input valves are closed, and you can include water.
  4. With old pipes need to drain the water as much as possible, disconnect the mixers and other devices.
  5. pipes disconnected from the sewer and they can be safely cut.

process of installing pipes can be different in different circumstances, but the standard stages are:

  1. If all the preparatory work and the dismantling of the completed filter is installed after the shut-off valve and meter.This is being done on the introduction of hot water.
  2. counters placed so that special arrows on them shows the direction of water movement.
  3. further held directly installing pipes.This process depends on the species.Since some of the highest quality - polypropylene pipes, the installation process, consider their example.Cutting the pipe fragments, they are connected in the right places, glued or welded by soldering.
  4. For compounds sold various adapters, angles, bends and special couplings that allow to connect pipes of different metals.
  5. heating time soldering pipes and fitting depends on their diameter.This can come out of this instrument.Plastic dries and hardens in less than a minute.
  6. Since the hot water expands slightly polypropylene pipes is not allowed their rigid attachment to the wall.It should be moving, which can be achieved by using plastic clips that attach to the wall dowels.
  7. Experts recommend for washing machine, boiler, shower and other appliances in the bathroom and the kitchen set up separate ball valves.They cover the water only to a specific object, so it is not necessary to turn off the whole house in the repair of the same technology.
