Plastic pipes for sewerage and water supply systems of a country house

Since the most ancient times, water has been an essential condition for the survival of all living things, and the fact that for people it has become essential, both for cooking and for hygiene, and for more than a dozen years, plumbing and sewerage systems in the house have greatly simplified life. modern man. Carrying out water supply in a summer cottage or in a private house has also become a necessity for a long time, and modern plastic pipes are practical and optimally suited for this process.

What are the general nuances of installing plastic pipes for water supply and sewerage into the house

At first glance, it is obvious that plumbing and sewerage are opposite in their functional purpose: the purpose of the plumbing is to ensure the flow of water into the house, and the purpose of the sewerage is to ensure the removal of used water and waste products from the premises. But when conducting communications to the house, these systems have common principles and are closely interconnected, since the sewerage system directly depends on the water supply system and cannot function without it.
Before starting work on the plumbing, you must carefully read the regulatory documents, which clearly describe certain restrictions in terms of their implementation and installation. Particular attention must be paid to sewerage. Improper installation of the sewer system and the formation of fecal infiltrate leaks will cause environmental contamination of the site. Penetrating into the layers of groundwater, the infiltration will cause them to be unsuitable for domestic use.

Both plumbing and sewerage are divided into two categories – internal and external. Each category has its own rules and regulations.

If you decide to independently engage in conducting and connecting communications to the house, then you should be familiar with the features of laying water supply and sewerage.

The best option in terms of the material from which the pipes are made are plastic pipes. Of course, when conducting water supply, you can use steel or copper pipes. But steel pipes began to be used less and less every year, as they are significantly inferior in terms of performance to polymer counterparts. As for copper pipes, as you know, today copper is quite expensive and practically inaccessible to most consumers.

Cast iron has been used for sewers for centuries, but today they are a thing of the past, because. modern requirements for the sewer system have increased. In addition to the requirements for the strength of the material, it is also necessary to comply with a high level of smoothness of the inner surface of the pipeline. This prevents the formation of deposits on its walls and the formation of plugs through which drains and sewage cannot pass.

Plastic pipes in this regard are the perfect option, both in terms of quality and at an affordable price. You can also buy plastic pipes on our website by contacting our manager by any of the indicated phones, or by ordering a callback. There is a delivery across Ukraine

Plumbing

Internal water supply as a network is divided into three components:

• Water supply for human consumption (eat for drinking, cooking).
• Water supply to the fire protection system.
• Water supply for production systems (garden, garage, sauna, etc.).

From the point of view of the engineering component, the water supply system can be divided into the following sections:

• Distribution network;
• Plumbing fixtures and fittings to them;
• Shutoff, mixing and control valves;
• A water meter assembly, which is usually installed at the entrance of the water supply to the house at the riser. It includes filters, a water meter, a check valve and a shut-off valve.

When installing the plumbing system, it is necessary to build a piping layout in advance, taking into account the layout of the house and the number of installed plumbing fixtures. Connecting a house to a water supply system consists of an input, an internal network (pipelines), sanitary appliances and connections to them. We also recommend that you provide for the possibility of draining the water if repairs are required in the future. Please note that it is impossible to connect a water supply system through which drinking water moves with a water supply system through which water moves for industrial needs into one system. As a rule, this remark is spelled out in the established standards.

For laying water supply to a summer cottage (suburban) area, as a rule, pipes with a diameter of 3/4 (for the main line) and 1/2 inch (for connecting to a specific consumer device) are used. Fittings, valves and taps are selected according to the diameter of the pipes.

In the event of an individual interruption of the water supply to the house, for example, during the repair of communications or the connection of additional outlets or valves, be sure to provide a shut-off valve. In addition, shut-off valves must be installed in front of each water consumer, for example, in front of a flush tank, gas water heater, etc. The normal, operating position of all these valves is “open”.

We recommend installing a tap to drain water from the system near the main inlet valve. The tap and valve should be placed in a box made of wood or tin. For a time when you will not live in a country house, it is imperative to drain the water from the water supply system, since the water remaining in the pipes at sub-zero temperatures may freeze, as a result of which the pipes may burst. As for plastic pipes, they are practical and reliable, but the situations are different and in order not to provoke your water supply to the exclamation “The system has defrosted”, if you do not live in a country house in winter, then the tap should be left open, and the valve – in closed.

Autonomous water supply

• When conducting an autonomous water supply system, basic knowledge is not always enough, and if you decide to connect individually to a pond, river, lake, well, spring or deep aquifer, then you will need to coordinate and obtain permissions in an administrative manner and it is more reliable to attract for these works of relevant specialists.
• Often, an autonomous plumbing system is combined with wastewater disposal. Sources for autonomous water supply systems can be interstratal, ground or underground waters (including perched water).
• With a shallow occurrence, perched water cannot be used, as it is not protected from pollution. There are rules for the use of water that apply to wells, groundwater, etc.
• Before connecting the water supply, it is necessary to analyze the water that you plan to use for the water supply and obtain a conclusion from the sanitary and epidemiological service on its safety.
• The specific rate of water consumption per person per day, depending on the availability of running water, irrigation and other things, ranges from 50 to 250 liters.
• The free pressure of water (the height of the water container above the ground at the entrance of the water supply to the house) should be approximately 10 m.
• If the house is not one-story, then you need to add 4 m for each floor.

Sewer system

• The internal sewerage system is located inside the house and collects wastewater from plumbing fixtures, as well as organizes their output to the external sewerage system.
• Internal sewerage is always gravity and uses a closed pipeline
  The pipeline is drawn as a straight section. If it is necessary to make a retraction, then special parts or structures are used.
• It is only possible to connect a sewer pipeline to a riser with a tee or an oblique cross. It is forbidden to use straight crosses if they are located in a horizontal plane. It is impossible to install indents on risers if it is planned to mount a plumbing fixture below these indents.
• In residential areas, it is best to use concealed wiring of the sewer pipeline. It can be installed in niches, under floor coverings, under suspended ceilings, under skirting boards and so on. But the open one is allowed to be mounted in basements, corridors, utility rooms, on technical floors.

When carrying out a sewerage system, it is very important to calculate the correct angle of inclination of the passing pipes, the efficiency of the system will depend on this indicator.

There are two ways to choose the right angle – calculated and non-calculated.

1. The calculation method implies that it will be necessary to make some measurements, such as:
the speed of movement of wastewater inside the sewer pipe (V)
pipe filling (H )
pipe diameter (d)
And make a calculation using the formula V=H/d,

The resulting indicator must be less than or equal to a coefficient depending on the material from which the pipes are made.

So this coefficient for plastic pipes is 0.5, and for all others 0.6.

2. The non-calculated method is usually used in the construction of sewers in private sector homes.

Because when conducting a sewerage system in private houses, it does not experience such loads that are inherent in multi-storey residential buildings or industrial buildings.

SNiPs provide their own coefficients for this method. For example, for pipes with a diameter of 40-50 millimeters, the coefficient is 0.03, for pipes of 85-110 millimeters – 0.02. That is, for each meter of pipeline length, the level decreases by 3 and 2, respectively.

Such indicators have been established experimentally: often, large fractions of suspended particles and feces move along the pipe with effluents. So, when the angle of inclination is lowered, these particles will get stuck, they simply will not be able to move at such a small angle. And in the case of an increase in the angle of inclination, a stop occurs, because the speed of the water increases, and it simply slips, leaving suspended particles in the pipe.

If it is planned that the water supply and sewerage pass according to the same scheme, then the following should be taken into account: the water supply network should always be located above the sewer.

If two pipelines for supplying cold and hot water are run in parallel, then the cold water pipe must always be located to the right of the hot water supply.
