Construction of a water supply system from HDPE pipes

In this article we will consider the main issues related to the construction of a water supply system from HDPE pipes. Before you start building a house, you need to consider how you will equip the water supply system. In order to minimize the number of breakdowns, it is necessary to carefully select materials. And the benchmark should not be kept on cost, but on quality.

Varieties of water pipes

High reliability is possessed by metal pipes. But in the plumbing facilities of modern houses, they are found less and less. Metal pipes can be made of such materials:

1. Steel.
2. Cast iron.
3. Copper.

In recent years, plastic pipes consisting of polymers have been very popular:

1. PVC (polyvinyl chloride).
2. Crosslinked polyethylene.
3. Polyethylene (including PND).
4. Polypropylene

Plastic pipes have the advantages of polymers and metal. They cost more than plastic ones. The most reliable and durable copper pipes. But they have a very high cost.

Advantage of HDPE pipes

Among the advantages of HDPE pipes for water supply, the following features can be distinguished:

• on the inner surface is not going to scale;
• the material is not susceptible to corrosion;
• high degree of extensibility;
• little weight;
• no need for additional isolation;
• installation will not cause difficulties even for beginners;
• plastic does not react chemically with water;
• high resource;
• withstands strong blows;
• low cost;
• completely metallic taste in the water.

Material flaws

But HDPE pipes for water supply have disadvantages:

1. Ultraviolet radiation adversely affects the material.
2. When laying pipes underground, the degree of soil mobility must be taken into account.
3. HDPE pipes in most cases cannot be used for laying hot water.
4. Strength is lower than that of metal.

But the cost of the material is very low, so many people choose such pipes for the construction of a water supply system.

Varieties of pipes PND

According to the classification of the pipe can be divided into:

1. Pressureless.
2. Pressure

By appointment, they are divided into such types:

1. Plumbing.
2. Gas pipelines.
3. Sewer.
4. Thermotechnical.
5. Technical
6. Pipes that are used as a sheath.

The outer shell of HDPE pipes can be:

1. Corrugated - used for hard soil types. The pipe consists of an inner smooth layer and an outer rough one.
2. Smooth, which are used for soft types of soil.

Please note that in the construction of water pipes it is necessary to use pressure pipes that are blue marked. Without pressure for these purposes are not suitable. In order to make hot water supply, pipes marked PE80 and PS100 are suitable.

Selection of water pipes

To determine the quality of the plastic pipe, it is not necessary to carry out chemical analyzes and lay it under the press. It is necessary to visually assess the condition, a high-quality plastic pipe has the following features:

• the color of the material is plain, the thickness is uniform:
• on the surface there is a marking and code of the manufacturer;
• the pipe must comply with GOST;
• all characteristics should be written on the surface - strength, wall thickness, diameter;
• its value should not be lower than that of most manufacturers.

A poor-quality plastic pipe can be recognized by the following features:

1. There are inclusions.
2. The color of the material is not plain.
3. The wall thickness is different throughout.
4. No marking (its absence is allowed only on technical pipes).
5. The material is heterogeneous.
6. On the surface of the pipe there is no data on technical specifications.
7. The cost of the pipe is many times lower than that of other manufacturers.

Pipes with low quality are made of low-grade materials - bottles, plastic glasses, etc. Therefore, their resource is very small, it can be 1-2 years.

How to mount pipes yourself?

When designing and building water pipes from HDPE pipes, all the features of the material must be taken into account. Installation must be carried out either with the help of special supports, or in the open. In order to lay plastic pipes, you need to make a small trench. To work, you need the following tools:

1. Conical knife.
2. Adjustable wrench.
3. Hacksaw for metal.

Fittings are used to connect. Namely:

1. Reducing couplings.
2. Couplings.
3. Tees.
4. Stubs.
5. Coupling for main line.

During installation, you need to connect the pipe to a source of water and consumers. The low-pressure pipes are flexible, but they cannot be bent; couplings are used for this purpose. If possible, it is better to turn the pipe gradually, around a circle with a large radius. This will increase the reliability of the water supply, as the number of connections will be minimal.
