Choose a pressure tank for a private house: what to look for when choosing a pump station

Choose a pressure tank for a private house: what to look for when choosing a pump station

Water supply of private homes, located outsideoutside of a centralized system, based on the water supply from independent sources - well, borehole or a storage tank (rarely). A special feature is the lack of underground sources of pressure required to lift the water to the top. Consequently, for the continuous provision of land or buildings need to purchase regulatory unit for the delivery of water - pumping station or in other words, pressure tank for a private house.


pumping equipment purchase based onRegistered characteristics of all parts of the system, their compatibility, for a particular source (well or wellbore) and for selecting a location for installation. Installation of the pumping station can be carried out at various stages: at the time of construction of the house, well drilling and repair work.

To install you will need closed flatthe minimum area (1-1.5 m?), located in the utility room, basement or on the street. If you find a better place in the corner of the house (bathroom, veranda, cellar), then take care of good insulation, even if the equipment is provided with the necessary certificates.

Aspect # 1 - device equipment

Until now equally actively use two types hydrophores:

  • Membrane fitted airtight elastic membrane which separates the compartments with water and compressed air;
  • diaphragmless in which water and compressed air are not separated are in the same reservoir.

The membrane is a dense rubberbag not in contact with the vessel walls, which houses. Hydrophores with the membrane device is compact, they are smaller and do not require a large area for installation - ideal for homes with deficient space. The volume of the tank - an average of 30-50 liters, but if necessary can find a 80-liter and 100 models.

Membrane pressure tank

Self-priming motor mounted on top (insmall models, in volume - set side by side) and is connected to a flexible tube tank. To adjust the air pressure used nipple. Through design features the membrane unit produces less noise. In some models, it provides for the possibility of replacing the worn membrane. If you have to buy a backup plan, make its certification, as the material (usually rubber) is in contact with drinking water.

diaphragmless hydrophore

Scheme pumping station hydrophore a diaphragmless having the form a large reservoir on the supports: the bottom of the tank water is at the top - compressed air

Diaphragmless tank - Uprightlarge cylinder volume is 100 liters or more. For water supply complete with diaphragmless hydrophore must be purchased self-priming pump vortex type. Optimum pump pressure must not exceed 0.6 MPa, since this figure is the highest for more hydrophores.

Regulatory standards allow the use of pumps with high pressure, provided the installation of the safety valve, a drain which leads into the sewer pipe.

filter WATER

For a better functioning of the hydrophore and protect it from damage on the tube before the device is mounted filter more water purification

The correct choice of equipment hydrophoreIt depends on the stabilization of the pressure in the device and all of the water supply system, the optimum pressure at each point of water pumping (the tap in the kitchen, in the shower, for watering the garden), protection against heavy loads.

It should be remembered that the work of hydrophore based on two factors:

  • Change pressure indicators;
  • the volume of water used.

That is, the number of automatic on-off one hour may be different.

The principle of hydrophore

Standard scheme of hydrophore Water fills the storage tank until the pressure switch is activated; pump is switched on again after emptying the tank and increasing the pressure inside the tank

Consider how the pressure affects the start. Assume that the crane included in the building. The volume of water in the device began to decrease, and the cushion of compressed air, on the contrary, to increase, which causes a decrease in pressure. Once the pressure has reached the minimum level, the pump automatically turns on and pumps water up to the moment when the air volume is reduced, so that the pressure does not rise. The pressure switch reacts to this and stops the pump. The maximum rate of pressure inside the tank sets of equipment manufacturer, but the operation of the relay can be controlled independently.

Aspect # 2 - volume and pressure unit

The main factor that should be relied uponselecting a volume accumulator - the average amount of water consumed by the family. Performance calculate, based on the amount of water spent for 1 hour. There are average values, but they are usually taken as the minimum. For example, a family of 4 living in a small private house, you need a pressure tank with a capacity of 2-3 m? / H. Large family living in a two-storey cottage with a garden plot should count on the performance of not less than 7-8 m? / H.

In addition to dry counting the number of residents to betake into account their lifestyle, some are cleaned once a week, others every day. A number of household machines and devices is also working on the water - washing machine and dishwasher, and a hot shower system, automatic watering the lawn or garden.

Calculation hydrophore characteristics

Tables offered by manufacturers are calculatedinstallation professional equipment If you are unable to figure the schemes refer to those skilled in the installation of water supply systems

However, one should take into account the maximum pressure,generated by the pump. As a rule, new hydrophore set of instructions, which serves as a clue in the table, the manufacturer specifies a list of important values ​​that need to be guided when installing the equipment. The operating pressure should correspond to all devices included in the water supply system. These are devices that are installed in the majority of private homes - different types of water heaters (cumulative or instantaneous), boilers single or dual circuit, boiler equipment.

Put pressure at the time of connectionequipment manually using the adjustment screws, but strictly according to instructions. For example, turn on the pump pressure - 1.7 bar, pump switch-off pressure - 3.0 bar.

Aspect # 3 - a source of water intake

Selecting hydrophore largely depends on the water intake source, which were:

  • well;
  • well;
  • water pipes;
  • pond;
  • storage tank.

To raise the water from the well or wells,We need a powerful pump. It works in continuous mode, turn on the water during the parsing on and off when the house is closed all valves. Customize it helps pressure switch - very convenient adjustment tool that allows you to control the water supply due to the increase or decrease in pressure.

Two variants of the pump can be used. One of them, the accumulator pump, pressurizes and thereby absorbs water, however, it has limitations. In addition to the depth (7-8 meters) it is necessary to take into account the horizontal sections 10 meters horizontally positioned pipes = one and a half meters of vertical pipe is lowered into the well.

Fence self-priming pump water

Driving diversion of water from the well or wells to help self-priming pump. Such a method has limitations - no more than the maximum depth of 8 meters

When the water level is too low, pressureset right in the hole, tooling platform at the desired height. High humidity, even with a good waterproofing ability to bring equipment out of action ahead of time, so this method is used only in a hopeless situation. Ideal for installation - a dry, warm, specially equipped basement.

Fence submersible pump water

The circuit operation of the pumping station for water extraction using a submersible pump. Most of the well has a depth of 20-40 meters, which shows the relevance of this method

Oddly enough, in small houses pumps outdown more often. This is for one reason: the number of on-off equipment more as water gain often, but in small quantities. Each model has a pump maximum inclusion Benchmark for one hour, for example, 25-30 times per hour. If the tenants will use water more often, especially the engine fails - due to overheating. To avoid damage, it is necessary to increase the interval between the switching on - this is one of the most important functions of hydrophore.

Homes located in the city orthe village is usually connected to a centralized water supply system. However, due to the small pressure often water is not supplied to the second floor, so also requires a pump station for forced feeding. WATER bundled with a vortex pump should be connected directly to the water supply. To the pressure was constant, it is better to choose an inverter driven motor.

Diversion of water from the tap

Sample pumping equipment layout when taking water from the tap. The advantage of this method - stabilization of the water supply in case of insufficient pressure in the central system

Thus, hydrophores optimal for use in private homes and cottages with such water sources as shallow wells and wells, unstable water pipes or ponds - for watering the garden.

Aspect # 4 - the conditions and the place of installation

The compact size of modern equipmentallow to place it in virtually any convenient corner - in the bathroom, on the terrace, in the back, in the hallway, and even under the sink in the kitchen. The noise level may be different, and at high rates it is definitely need more insulation.

By installing a pumping station, it must be rememberedon standards and requirements for the installation of electrical equipment and water supply systems in private homes. Some of the rules relating to the installation room equipment:

  • room area - not less than 2 m × 2.5 m;
  • ceiling height - no less than 2.2 m;
  • hydrophore minimum distance from the wall - 60 cm;
  • the minimum distance from the pump to the wall - 50 cm.

The requirements are presented not only to the pumpequipment, but all the attendant systems. All electrical cables, occasion, lights, lamps must have a high degree of protection against moisture. The room temperature should not be negative, the best option - from +5 C to +25 C?.

Location for the hydrophore

In a large house there are no problems with accommodationhydrophore: often it is installed along with the other pumping equipment in a dedicated room, providing easy access for maintenance and repair

Necessarily the presence of ventilation, whichIt provides a constant cooling of the engine. Insurance emergency accident - and the slope of the floor sewer hole with a capacity equal to the capacity of the pump. Even the door unit must conform to install the equipment, so if necessary you can easily add or take out the largest element of the pumping station.

Set on the ground floor

One of the best accommodation options pumping equipment - in the basement of an apartment house, whose role can also play a cellar or basement

If vibration and noise levels exceed hydrophoreregulations, or more simply, prevent to live, endure it outside the building and placed in a concrete pit - a small insulated and sealed hole in the ground. To protect the walls from shedding use concreting with reinforced mesh, reinforced waterproofing film. To use Styrofoam insulation sheets arranged in layers, not thinner than 5-8 cm.

The role played by reinforced concrete slab of the ceiling, and doors- Hatch sealed lockable. Rain water can penetrate into the gap, so on top of the hatch cover sheets of roofing material or plastic waterproof cover. On sale there are other design options, masking sewer manholes and engineering, they are in the form of stones and thickets of grass.

Set in a well

If a pressure tank is installed directly in the borehole or well, it should be possible to protect the equipment against water penetration, making easy access to the engine and pump warm room

The descent into the well is carried out on the stairs,attached to the wall. All the conditions are similar to the placement requirements in the utility room - need lighting, ventilation, sewer drain and thermal insulation (particularly in the northern regions). Keep in mind that the pumping station the engine is not protected against flooding, so dangerous for users. All these nuances should be considered at the stage of the purchase and selection of equipment.
