The need to adjust the water pressure switch for the pump
Setting up the relay independently or with the involvement of qualified specialists is required in any case when assembling the pumping station from separate parts. It is possible that setting the water pressure switch will be required even if the finished pumping station is purchased from a specialized store.
This is explained by the fact that each water supply system is characterized by individual characteristics and the needs of residents are also different. The degree of water pressure in a house with a shower, sink and bathtub is significantly different from a spacious country house with a jacuzzi and hydromassage. In this case, it is necessary to adjust the water pressure in the water supply system and configure the equipment individually for each case.
When deciding how to connect a water pressure switch, it should be remembered that in addition to the initial setup that is performed during the installation of pumping equipment, during operation it is necessary to monitor and adjust the operation of the equipment.
In addition, in the case of replacing or repairing a separate element of the pumping station, additional adjustment of the water pressure regulator relay is also required. It is worth saying that the process of adjusting equipment is similar to the procedure for setting it up.
What is a pressure regulator
The pressure regulator is a small device that is used to deal with water hammer. Also, with its help, you can control and, if necessary, adjust the water pressure in a particular system. The use of this device allows you to optimize the work and increase the service life of engineering communications. Often, a pressure reducer is used at such facilities:
- skyscrapers;
- work shops;
- technological facilities;
- residential buildings.
Devices used to adjust the pressure in the system are divided into dynamic and static products. The first type is used in main pipelines at industrial enterprises. They allow you to regulate the flow of fluid in systems. As for statistical products, they are installed in pipelines with unstable water supply. That is why statistical gearboxes are used in multi-storey and country houses.
We deal with the law.
First, it should be noted that the apartment is owned, not municipal. Next, we use the Internet, a consultant plus or a guarantor. The main thing here is not only to find the norms that are responsible for plumbing equipment, but most importantly, do not forget to check the relevance of this law and by-laws. It was possible to find out quickly enough, what you need:
Decree of the Government of the Russian Federation dated August 13, 2006 No. 491 “On approval of the Rules for the maintenance of common property in an apartment building and the Rules for the maintenance of common property in an apartment building and the rules for changing the amount of payment for the maintenance of residential premises in the event of the provision of services and performance of work on the management, maintenance and repair of common property in an apartment building house of inadequate quality and (or) with interruptions exceeding the established duration.
We will leave everything that relates to the composition of common property for later. Let's move on to the main thing, namely to the 5th paragraph of this law:
Device description
The device of almost all types of pressure switches that are equipped with pumping stations is approximately the same. The working elements of the pump are fixed on a metal base:
- Membrane,
- Piston,
- Metal platform.
- Electrical contacts.
There is also a large and small spring, all housed in a plastic case.
When a water pressure switch is connected, the process proceeds according to the following principle: the pressure exerted causes the membrane to push the piston, which raises the platform. She, in turn, puts pressure on a large spring and compresses it. The resistance of the large spring to the applied pressure limits the movement of the piston.
There is a small distance between the large and small adjusting spring, but it is quite enough to adjust the operation of the instrument cluster. The platform, which is affected by the membrane under pressure, rises to the edge of the small spring.
As a result of increasing pressure on the platform, its position changes. This leads to switching contacts and changing the mode of operation, therefore, it turns off. The contacts are switched using a special hinge with a spring. After the platform passes the level of the hinge location, the position of the electrical contacts changes accordingly and the power supply circuit is opened.
Turning off the pump stops the flow of water. With the flow of water from the accumulator, the pressure on the membrane gradually decreases, and the platform begins to lower. Having fallen below the level of the location of the spring hinge of the electrical contacts, it again causes the contacts to rise and, accordingly, close the circuit. It does not hurt to know which is the best water pressure regulator in order to make the right choice.
The pump starts to work, pumps water into the hydraulic tank, and the cycle repeats automatically.
Device adjustment
Many owners are wondering how to adjust the water pressure regulator in the apartment. This task can be easily done by hand. Most devices come with a preset setting. According to this, the pressure in them is 3 bar. But, if necessary, you can reduce or increase this parameter yourself.
Disassembled water pressure reducer
You may need a wrench or a wide screwdriver to make adjustments. The choice of tool depends on the gearbox model. Of course, in modern devices, configuration is done manually without using any additional tools.
First of all, you need to make sure that the water pressure reducer in the water supply is securely installed. After installation, the device opens the water supply. At this stage, you need to check the system for leaks. To prevent such problems, sealing material should be used when mounting the gearbox.
Adjustment of the water pressure reducer in the apartment is carried out with the taps closed. At the bottom of the device there is an adjusting head, which is responsible for adjusting the pressure of the liquid in the pipeline. If the pressure needs to be increased, the head rotates clockwise. Otherwise, the rotational movements are performed counterclockwise.
One full rotation of the head allows you to change the pressure by 0.5 bar. This will be noticeable by the movement of the arrow. Thus, the water pressure regulator in the apartment is adjusted. The work can be easily done by hand.
Scope of use of the device
The pressure reducer simultaneously performs several functions. First of all, it is used to protect plumbing fixtures from high pressure. So, most plumbing and household appliances are designed to work when the water pressure in the pipeline does not exceed 3 atm. If this indicator is slightly higher, then the water supply system is under serious stress. Subsequently, valves, connections and other elements of the system and plumbing fixtures suffer

Also, the gearbox is used to combat water hammer, which can occur both in industrial enterprises and in residential buildings.As a result of a sharp jump in water pressure in the water supply system, a water hammer occurs, which can damage the structural elements of the system. There are cases when such a sharp jump led to the rupture of the boiler. Therefore, experts recommend installing a gearbox, as it will prevent the occurrence of such problems.
It is very important to consider the installation in the water supply system of the apartment
The pressure reducer is widely used in homes where the pressure of cold and hot water is constantly jumping. Adjusting the water pressure regulator in the apartment will solve this issue once and for all. Also, lowering the water pressure in the apartment will reduce its consumption by 25% or more. Details on how to choose a water pressure reducer.
