How is the water pressure regulator used in the water supply system: types and methods of installation
The choice of plumbing equipment must be approached responsibly. All manufacturers' requirements must be followed. The water pressure regulator in the water supply system can prevent many troubles. Pressure surges inside the plumbing system can lead to breakage of even expensive and proven structures. In this case, a special device will help.

Using regulators
Units that help to maintain a certain amount of pressure are used for commercial purposes and in everyday life. They have the following advantages:
- protect networks from water hammer;
- eliminate equipment failure due to pressure drops;
- water consumption decreases;
- when the working pressure decreases, the noise produced is also reduced;
- at the outlet, the head is constant, although there may be surges at the inlet.
Before installation, it is worth studying all the input and output elements.
With the help of a water pressure reducer in the water supply system, the movement of the liquid is stabilized, and hydraulic shocks are extinguished.
The pressure control device is an integral part of the plumbing structure
Such products are used in water supply networks for various purposes, in structures for irrigation, in water filling stations and in various fire extinguishing systems.
Helpful information! Regulating mechanisms are installed at the inlet to the water riser or to the building itself.
Installation features
This device is placed at the inlet to a residential building, behind pumping equipment or valves. The water pressure reducer in the water supply system allows dosing the pressure in the mains.
You can install the gearbox yourself
If the device has a large diameter, then a filtering device is installed to purify water. A shut-off valve is also mounted, which is necessary for ease of maintenance or repair work. Manometers are mounted on the line in front of the regulator and after, allowing for adjustment and systematic inspections.
Experts recommend mounting a pressure gauge for better device performance
When choosing a device, it is necessary to find out the permissible head loss and flow rates.
Helpful information! Before buying, you need to consider the possible speed in the inlet pipe. These indicators are indicated in the documents attached to the product.
Design features and types
Before buying a water pressure regulator, you need to choose the right option.
Lever flange pressure regulator in the water supply system
The lever model restrains the excessive pressure in the pipeline network before and after the installation of the mechanism. This helps regulate the flow.
A design feature is the presence of weights
The device consists of a steel or cast iron body, a lever structure with supporting elements, rods with valves, a cover and a special mechanism with a membrane. Valves open access under the influence of loads. They help regulate the head after the installation site of the structure. The setup steps involve special weight calculations and cargo accounting.
Household regulator
The water pressure regulator in the domestic water supply system is manufactured by the Russian company Pascal. Household appliances help to extend the service life of the valve and pipeline mechanism. Also, devices can reduce noise, reduce pressure and vibration.
Household structures can have different shapes.
Installation of such gearboxes reduces costs water supply and electricity consumption.
Electronic variant
An electronic device starts a low-power pump when water is taken from the system. This mechanism is silent. A special sensor protects against possible water hammer and against the operation of the pumping mechanism without water.
Electronic products allow for high-quality system automation
The regulator consists of a special diaphragm, a plate, a sleeve for connecting to a cable and a main body element.
Helpful information! The electronic device is mounted up to the first water intake mark. The presence of inlet pipes facilitates the installation of the mechanism in the line of the main. Before starting the control product, the pump container must be filled with water.
Electronic water pressure regulator in the apartment: how to regulate the mechanism?
Manufacturers set the optimum pressure in the design with a value of 1.5 bar. It should be borne in mind that the nominal value should be 0.8 bar higher than the starting value. The starting value is adjusted with a special screwdriver.
The installation scheme has some peculiarities

Direct acting pressure regulator
A flange valve is a product of an industrial water pressure regulator in a water supply system. The price for it varies from 30 thousand rubles. Values are adjusted using network settings.
This diagram allows you to understand how the direct action mechanism works.
The device consists of the following parts:
- boxes with inlet and outlet flanges;
- bushings;
- large valve;
- membranes and impulse pipes;
- pilot valve parts.
If the value exceeds the possible threshold, then the liquid enters the valve container. In this case, the diaphragm closes the passage opening of the regulator. After reducing the pressure, the membrane opens the passage.
Honeywell device
Household models include Honeywell. The device contributes to the economical distribution of water, and also helps to maintain constant values from the network. The manufacturer produces combined models with a regulator and filters in one housing.
The model of this manufacturer is distinguished by its convenience and pleasant design.
Helpful information! Purification of water from various contaminants can improve the performance of the water supply system. Wherein filter can be washed without turning off the water.
Regulators for apartments
The regulating mechanism will help to improve the quality of water supply in the apartment. For a residential building, you can choose a device with a throughput of 3 m3 / hour.
Appliances used for apartments have a certain device
The following rules will help to correctly install the device:
- the device must be installed in a heated and accessible room;
- no extraneous influences should be exerted on the surface of the product;
- the arrow on the box should point in the direction of flow;
- before installation, the lines are cleaned;
- it is recommended to install a strainer.
These diagrams allow you to understand how the installation of the control device is carried out in the apartments.
Helpful information! It is recommended to install a special valve to facilitate maintenance of the device.
The principle of the mechanism
The reducer is a pressure control and regulation valve. The work of the structure is to smooth out the forces of the two types of equipment under the pressure flow. Regulators are of two types:
- devices with pressure regulation in the area up to the device;
- mechanisms that stabilize the pressure in the lines connected to the outlet of the structure.
The advantage of such devices is practicality and reliability in operation. Subject to the settings, the mechanism is able to maintain the specified indicators.

How to adjust the device?
When adjusting the device, the installed pressure gauge helps. Turn the adjusting screw until the desired values appear on the gauge. This screw is installed on the equipment case. It can be moved with a hex key.
The product is adjusted using the mounted pressure gauge
The adjustment is made as follows:
- the valve opens;
- all water sampling points are closed;
- the required pressure indicator is set;
- the water tapping points are opened and the pressure value set in the parameter is checked.
A special adjusting knob allows you to set the desired pressure value
Helpful information! The permissible value of fluctuations in the pressure indicator should be within 10%.
A high-quality filtration design is required for full operation of the device
