As you know, after a long operation, the pipes become unusable and they must be changed. For this, the scheme is drawn, new pipes and connecting parts are selected. Well, then, the water supply is installed. We will tell you more about this process below.
Installation of the water supply – make a diagram and calculate the material

Before you mount the system, it is important to make a number of preliminary measures (preparation). First of all, a scheme is drawn up, which indicates all the plumbing devices located indoors (shells, toilets, showers). It is at this stage that it is important to determine what you want to see and what plumbing devices? What reinforcement will be used in this case? Where exactly the connection to the main riser, angles, turns in the system will be carried out? It is important to know all this in advance and reflect in the drawing on paper.
At the second stage, you need to choose the material. There are a huge number of plastic (PVC, polypropylene, metal -plastic, etc.) and metal pipes (copper, steel). Also on the shelves of stores there is a wide variety of connecting elements for them (share, crimping, pressing, etc. And often these details are more expensive than the pipes themselves. Therefore, for competent calculation, it is important to know the exact number of both materials. Only with this approach can you create a durable and reliable tap system.
DIY water supply installation – select pipes and connecting parts

The modern market has a wide range of various pipes. All of them have their disadvantages and advantages. But how to determine which ones are suitable for you? How to choose the best? To do this, we will briefly describe the most popular types.
Steel pipes are attributed to metal products. Conventionally, they will be divided into material without coating and coating (galvanized). Among the main advantages are distinguished: strength, high quality and durability. Of the shortcomings: the possibility of rust, the complexity of the installation, as well as the need to complete sealing of all compounds.
Copper pipes for the water supply – are used in all kinds of water supply systems, heating, air conditioning, gas supply, and t. D. Of the main advantages, they are distinguished: resistance to corrosion, exposure to sunlight, is suitable for any types of systems and can be mounted using a single technology, low installation cost. From the shortcomings: the possibility of connecting only with the help of a soldering apparatus, all disposable structures.
Metal -plastic pipes – have a metal frame, which on both sides is covered with plastic. Usually, such products combine the properties of metal and plastic at the same time and therefore are considered one of the best. Of the advantages, they distinguish: flexibility, simplicity and ease of installation, lack of rust, low weight. Of the shortcomings: the high cost of connecting parts (fittings), the susceptibility of hydraulic boards.
Polypropylene pipes – are the best of plastic. Suitable for any water supply (hot and cold). Can withstand t to 80-100 s. Polypropylene water supply is more reliable and high -quality. The average service life is 55 years.
Polyethylene pipes – recommended only if there is a cold water supply. For hot water they are not suitable. However, today the stitched polyethylene pipes are being produced, which is considered to be suitable for hot water supply. One way or another, every day this type of pipes is used less and less.
On a note! The pipe pipe is not recommended for the use of PVC, since substances are distinguished for humans.
Installation of a water supply from polypropylene
Installation of polypropylene pipes, in fact, is the same as the assembly of the designer. The difference in this case is that during installation there should not be errors in the calculations of materials, incorrect welding, cutting of pipes, etc. D. All this in the future can lead to an accident and flooding. That is why it is necessary to make a drawing scheme at the initial stage, in which the main objects will be drawn and the calculation will be made. After a competent choice of all parts, connections and materials, they begin to install. It is desirable that it is performed by highly profile specialists.
So, at the initial stage, water is turned off and the last pipeline is dismantled (cut out). Then the polypropylene pipes are cut off along the corresponding length. Make marks with a marker in those places where fittings will be located (their depth of entry). Also note those areas where compounds will be carried out with other pipes. The pipe and fitting are simultaneously planted on the nozzle of the device and the corresponding time is heated depending on the thickness of the pipe. After warming up, they are removed and connected to each other exactly in those marks that were made by a marker. The cooal time of the connection is on average 20-30 seconds. So, gradually connect all the pipes of the system.
