Water supply of a private house. The secrets of the installation. External and internal water supply

A private household’s water supply is a necessary component for the efficient operation of daily tasks like cleaning, cooking, and personal hygiene. In order to ensure efficiency and dependability, the installation process requires careful planning and execution from the time water enters the house until it is distributed throughout. This article explores the complexities of private homes’ internal and external water supply systems, revealing the trade secrets associated with their setup and upkeep.

The journey to a house’s external water supply starts at the main water line, which is usually connected to a private well or a municipal supply. Water is transported from its source to the dwelling via this main line, which serves as a lifeline. This main line must be installed correctly because any flaws or leaks could waste water and possibly cause property damage. To guarantee the longevity and effectiveness of the external water supply, factors like pipe material, burial depth, and protection against freezing temperatures must be carefully taken into account.

After the water enters the building, attention turns to the internal water supply system, which is in charge of supplying water to the different fixtures and appliances in the home. To maximize water flow and pressure throughout the property, this complex network of pipes, valves, and fittings needs to be carefully planned. Every space that needs water, from bathrooms to kitchens, needs to be carefully considered during the installation process to prevent problems like uneven or low water pressure.

Choosing the right fixtures and materials is one of the keys to a successful water supply installation. Premium pipes, like PEX or copper, provide long-lasting resilience to corrosion, guaranteeing minimal upkeep and longevity. Furthermore, using energy-efficient fixtures—like low-flow showerheads and faucets—can contribute to long-term water conservation and lower utility costs.

Regular maintenance and inspection are also necessary to keep a water supply system in good condition. Regular inspections for corrosion, leaks, and abnormalities in water pressure can help identify problems early on and prevent expensive repairs. Furthermore, freezing can be avoided and the water supply system’s lifespan can be increased by insulating pipes in cold climates and shielding outdoor fixtures from inclement weather.

To sum up, installing internal and external water supply systems is essential to maintaining a private household’s comfort and functionality. Homeowners can benefit from a dependable and effective water supply for many years to come by comprehending the nuances of water supply installation and putting best practices into practice.

Basic rules for developing schemes

Comprehending the fundamental principles of wiring schematic design is imperative for accurately and adequately planning the installation of a water supply system for a private residence. The hot water supply scheme and the individual cold water supply scheme depict all the events related to the proper placement of the water heater, including locations with water clearance points. It also establishes the locations of drive valves, passing elements, and water supply pipes.

The location of the pumping station, filters, and reverse valve system must be accurately determined in the event that the well’s continuous flow is scheduled or excavated beforehand close to the well house.

The following components are included in the simple rules for creating such schemes:

  1. The accumulative tank, according to all installation rules, is connected to the main tap pipe. When water supply through the use of central heating, the pressure will be changeable. This means that it is necessary to install an additional pump that provides stable water pressure.
  2. Before the water intake into the container, it is advisable to ensure preliminary filtration from extraneous impurities and garbage.
  3. During the absence of water, the pump is at risk of burning. A specially installed dry pass sensor will allow you to keep track of that the power is disconnected on time.
  4. In the event that water is carried out from the well, a stable pressure will ensure the installed pumping station. She already has a built -in burning protection.
  5. Float switch – the necessary element in the diagram. He will serve as protection against transfusion.

Installation of external water supply

Think about the primary requirements for installing the external water supply.

The depth of freezing

Water supply communications are typically laid at a depth. In order to accomplish this task of setting up a private home’s water supply, the trench needs to be dug out. It is crucial to consider how thorough the preparation is for it. It directly depends on the depth to which the soil freezes as well as the temperature, which varies throughout the year depending on each particular region. Adding an additional layer of heat-insulating layer to water supply pipes is advised to prevent them from freezing.

Standard trench used to install water supplies

In this case, the pipeline’s point of withdrawal must be carefully considered, taking into account the following subtleties:

  • It is recommended to make a small gap, approximately 130-150 mm on all sides in the place where there is a hole for installing and welding the water supply pipe. The destruction of communication will become minimal if the wall is subjected to subsidence or deformed.
  • Additional thermal insulation is necessary where the pipe passing between communications as a result of an insufficient joint is outdoors.

Pipe diameter

Selecting the appropriate diameter of pipe will enable more cost-effective installation of the water supply.

Determine the parameters of the lines that will serve as a summary of the hot and cold water supplies, as well as any consumption points that branch off of them. The starting point is the total length of each line.

Frequently run a 32 mm-diameter pipe into the home. Rarely, a bigger diameter is employed.


The pipeline must be insulated using specialized building materials made for this kind of work:

  • Foam insulation;
  • Glass wool;
  • Polystyrene "shell";
  • Basalt cotton wool in cylinders.
  • Foamed rubber

These are the primary materials, the selection of which is influenced by local weather patterns, individual tastes, and cost range.

Types of pipes for water supply

Depending on the intended use, a private home’s water supply can be installed using one of several primary types of pipes:

  • Metal -plastic. Aluminum water supply pipes covered on all sides are not subject to corrosion and bend well. But it should be borne in mind that they do not withstand temperatures above 95 degrees. With such pipes it will always be necessary to monitor the operation of the boiler. To install metal -plastic pipes of water supply is not difficult and yourself. The main thing is to ensure that during the installation process all joints are connected hermetically. Are not quite suitable for the outer pipeline
  • Steel. Are considered one of the most durable and durable. When installing water supply with your own hands, these pipes must be mounted, constantly cutting the thread at all points of the connection. Often, a welding machine is used during installation.
  • Polyethylene. Ideal for installing a water wiring system. They are quite resistant to temperature differences, are quite simple for installation, as they have plasticity.
  • PVC. For home use, this material is not recommended due to the ability to enter into a chemical reaction.
  • Polypropylene. Sufficient budget option. But at the same time durable, since it is not subjected to corrosion over time. Installation and installation of such pipes is carried out, as a rule, by welding.

After the scheme has been established, the water supply pipes must be chosen. Whether the trigger or collector method is used directly affects this process.

Internal water wiring schemes

The supply of hot and cold water is handled by two primary systems:


Troinic wiring configuration

It is referred to as consistent otherwise. Since less material is used in this method, it is regarded as a cost-effective choice. One of the drawbacks of this kind of arrangement is that it may lower water pressure if multiple locations for water clearance are utilized at the same time.


Wiring for the cold and hot water supply collectors

A parallel water supply scheme is another term for it. In this instance, one or two collectors are set up, one for each type of water—hot and cold. The collector is connected to the lines that go to the water clearance point. More pipes must be used in this method. However, there won’t be a chance of a drop in water pressure.

Pressure in water supply. What should be?

When a private home’s water supply is organized in accordance with all legal requirements, a regular water stream is also provided, guaranteeing the water-saving system’s comfortable operation. These elements guarantee the pumping device’s and all associated sanitary devices’ functionality and suitability for use. For this reason, it’s critical to understand the ideal water pressure for a private residence.

Bars and atmospheres are the two units used to measure the water supply. That’s actually the same. There is variation in these measurement units measured in hundredths of units. Remember that water flow increases to a height of 10 meters at one atmosphere of pressure.

Three bars is the ideal pressure for the water supply system to run efficiently. All hygienic appliances function normally with such a set, and malfunctions are prevented in the shaped components and the regulatory environment.

When there is too much pressure applied, delicate devices could malfunction or break. Six bars should not be reached by the pressure.

Pumping stations for water supply. When you need to put it?

Those who are unable to connect a water supply from the central water supply system must decide which pumping station to use. In this instance, the water will flow straight from the well or wells. Water can be raised to a height of nine meters by the pumping station. It’s convenient to use this option to water wells and wells.

Pumping installations have the benefit of having an accumulator and a unique blocking prevention mechanism.

Whether a private home is indoors or outdoors, there are many factors to take into account when setting up a water supply to ensure reliable, effective operation. In order to prevent leaks and guarantee a continuous supply of water from the source to the house, it is essential to install pipes and connections correctly outside. Internal variables that affect water usage optimization and waste reduction include fixture placement, pipe material, and layout. The key to a well-functioning system that satisfies household needs while conserving this valuable resource is understanding the nuances of both external and internal water supply, from selecting the proper pipes to strategically placing valves and faucets.

The main sources of water supply


Pumping station that uses a well to pump water

One of the primary water sources, the well has been in use since antiquity. Surface water is supplied by centrifugal pumps. Submersible vibrating pumps can also be used to supply hot and cold water. Even in the early stages of the house’s communication design, the well’s depth is determined using data from the local geological exploration.

It is preferable to use qualified experts to plan the well installation. In this instance, the dangers of incorrect ring installation and subsidence can be avoided.


The most practical and widely used method for setting up manual water supply communications is digging a well. Drilling should only be done by experts in the field who have the required equipment and knowledge.

Artesian and filter wells are differentiated based on their respective locations. The former have pure water from deep wells. "Shallow" filter wells.

Central water supply

According to all indications, installing the system by connecting it to the central water supply is the most practical and convenient choice. Obtaining an insert permit from the authorities will be the only task required.

However, it must be acknowledged that regular payment will be required in order to use such water "on a common basis." Furthermore, a lot of people are dissatisfied with a private home’s central water supply since it nearly always has some chlorine in it. However, installing a second, specialized system for water purification is always an option.
