Which accumulator to choose for the water supply systems of a private house? How it works + Video The hydroaccumulator is a necessary element of the station in domestic water supply systems, designed to take over some volume of liquid, and overpressure.

Let us analyze in more detail what the connection of the hydraulic accumulator is for: Which accumulator to choose for the water supply systems of a private house? How it works + Video

  1. The need to accumulate a certain volume of liquid;
  2. The need to take excess pressure;
  3. The need for damping hydraulic shocks in the water supply system;
  4. Maintaining water pressure even when the pump is off;
  5. The hydraulic accumulator gives the pump a break, it turns on much less often;
  6. At peak fluid consumption, the hydraulic accumulator softens them.

For a clearer understanding of the function and device of the accumulator in your water supply, remember the design and purpose of water towers. Their function was to store water and provide water pressure in the system.

Which accumulator to choose for the water supply systems of a private house? How it works + Video The water tower, as well as the hydraulic accumulator, significantly improve the operation of the entire system: the first is due to the potential energy of the water raised above the ground, the second is due to the potential energy of the air compressed in it.


Before starting to use, carefully read the technical documentation to be completely sure of the purpose of this mechanism.

Hydraulic accumulators for water supply

Which accumulator to choose for the water supply systems of a private house? How it works + Video Hydraulic accumulator - This is a container that accumulates water, with a membrane or a pear inside, with a filter - usually also inside, various pipes, valves, mechanisms and structures to ensure the normal operation of the water supply outside.

Hydraulic accumulators have two types of construction - membrane and with a rubber bulb.

Moreover, the membrane and the pear are hidden inside the accumulator.

The membrane, as a rule, follows the shape of the tank.

Water enters it from below. On the outside, the membrane is surrounded only by air.

Usually the water inlet is at the bottom and the air inlet is at the top. But sometimes the water entrance can be located on top.

For hydroaccumulators with a pear, the entrance is similar, but there are models where the water inlet is located on the side of the tank, and the entire device is horizontal.

The pear is attached from one side, or from both ends, and always to the opposite sides of the tank.

Which accumulator to buy?

We recommend buying a 24 liter accumulator and placing it as close as possible to the pump - and then the water supply system will work perfectly.

Which accumulator to choose for the water supply systems of a private house? How it works + Video In the presence of a large house and a large family, the need for water increases, and then it costs in advance calculate everything.

Let's first consider the on-off of the pump. A good option is not to run the pump more than 30 times an hour.

The pump capacity is usually about 40 liters per minute.

And in the accumulator, air and water equally divide the space of the tank. Therefore, it is better for you to purchase a hydraulic accumulator with a volume of up to 100 liters.

Which accumulator to choose for the water supply systems of a private house? How it works + Video Let's calculate the water consumption in the house for one minute.

For example, during the hour of peak fluid consumption you will spend : 8 liters for the kitchen area, 10 liters for the bathroom, and 6 liters for the toilet.

And this is only a minute, and if there are two toilets, then you get 30 liters.

In the hydroaccumulator tank we have only half free - you need to remember this. Therefore, a hydraulic accumulator up to 100 liters is ideal for you.

To reserve water in case of water cut-off - proceed from your water consumption for each family member.

Below we will consider how to choose a hydraulic accumulator in a private house in terms of the pressure indicator.

The pressure should not be less than that in the water supply system of the whole house. With a pipe height of 10 meters, you have a pressure of 1 bar. The water tap functions normally at 0.5 bar.

As a rule, the manufacturing plants provide a pressure of 1.

5 bar. Although, the pressure in the accumulator will still have to be checked twice a year.

Hydraulic accumulator and its connection diagram

Installation and installation of the accumulator must be carried out in full compliance with all norms and instructions of the manufacturer.

The ideal option would be to hire a specialist.

If you nevertheless decide to start the installation yourself, then you must not violate the manufacturer's instructions, and you should also show exact prudence and caution:

  • Which accumulator to choose for the water supply systems of a private house? How it works + Video If the accumulator has external damage, then it is not worth installing;
  • It is necessary to strictly follow the manufacturer's conditions in terms of the installation site and principles of operation hydroaccumulator;
  • The mass of the tank should be taken into account during installation, and do not forget about how much water will be in it after installation;
  • Sometimes it will be necessary to drain water from the accumulator tank;
  • Freezing of water in the accumulator is also inadmissible.

    The room should be well heated;

  • All elements and parts of the accumulator should not be subjected to static external loads;
  • It is necessary to protect the accumulator from moisture and various external mechanical damage;
  • When buying a large accumulator 750 liters, calculate in advance how you will get it into the house.

Which accumulator to choose for the water supply systems of a private house? How it works + Video When installing a hydroaccumulator some problems may occur. All hydroaccumulator malfunctions in most cases can be eliminated - just call a specialist, or make repairs yourself.
If the accumulator pump turns on too often, this indicates several malfunctions of the accumulator.

For example, this could mean the following:

  1. There is no compressed air in the tank.

    This problem can be removed when pumping air with a car pump;

  2. Damage to the membrane. Just replace it by contacting the right specialists or with your own hands. When replacing, use only the original diaphragm;
  3. The body is damaged. To eliminate this problem, repair the housing by hand or contact a specialist;
  4. Small difference between the pressures when turning the pump on and off. For good work, you just need to change the pressure on and off of the accumulator pump.

If you find a leak from the valve, it means that the diaphragm is damaged. You can replace it at the service center, or by yourself.

If the air pressure in the accumulator has dropped below the calculated value? Which accumulator to choose for the water supply systems of a private house? How it works + Video In this case, blow out the nipple, restoring the ideal pressure inside.

If there is no pressure in the system, then there can be two reasons:

  • There is no compressed air in the accumulator. To eliminate this drawback, you just need to upload it back.

  • The pump does not supply a certain pressure. Just check the pump, most likely the fault is in it.

The cost of a hydraulic accumulator for water supply systems

Which accumulator to choose for the water supply systems of a private house? How it works + Video The cost of accumulators is different. Generally, the price is influenced by the volume, brand and country of the tank manufacturer. Prices may vary depending on the regions of Russia.

Basically, the cost of a hydraulic accumulator starts from 1000 to 8000 rubles.

When buying a hydraulic accumulator for a water supply system, we consider the pump to be the main thing in it. If the pump is working properly, there is also water.

In this case, the pump takes water from the well and pumps it into the hydraulic accumulator, or more precisely, into the pear or rubber membrane inside the tank.

Water will be pumped into the accumulator to a certain level, and will stop when the pressure is at its maximum.

And when the shower or washing machine is running, the pressure sensors will signal the pump to resume its work.

The hydroaccumulator will make your country house really comfortable and cozy.
