Autonomous water supply of a private house implies the use of powerful equipment that is responsible for the supply of water from a well, well or storage tank. A feature of such a water supply system is the absence of natural pressure, which must be ensured through the use of a pumping station and a hydrophore device.
Features of an autonomous water supply system
Pumping station in a private house built on the use of special powerful equipment that pumps pressure in the system, providing the corresponding pressure of water in the pipes. It is on the correct choice of such pumping equipment, which is controlled by automation, which will subsequently depend on the quality of water supply of a private house, and, consequently, the comfort of living in it. Drainage stations in private houses can differ in their connection scheme and principle of operation.
Currently, there are several types of hydrophores that are used to equip autonomous water supply systems:
- Membrane type, which have a sealed flexible membrane separating the tank with air and water.
- Membrane-free type, in which drinking water and compressed air are in the same compartment without separation by their partition.
Used elastic membrane in hydrophore pumps - This is a durable rubber bag that does not allow the walls of the tank to come into contact with water. One of the distinguishing features of such membrane hydrophores for a private house is their compact size, which allows you to install equipment in a small utility room and storage room.
For private houses with an area of not more than 100 square meters, such membrane hydrophores are the best choice, as they combine simplicity of design and excellent performance. On sale, you can find tanks with a volume of up to 60 liters, and if necessary, larger containers are made to order, accommodating 110 liters of clean water.
The installed suction motor is fixed on top of the tank and connected to it using a flexible pipe. The presence of a special nipple allows you to properly swing and easily adjust the air pressure, respectively, you can correctly configure the system, which will operate in fully automatic mode. Suction motors used today practically do not make noise, which increases the usability of such hydrophores.
Membraneless tanks are durable metal vertically placed cylinders with a volume exceeding 110 liters. Typically, such hydrophores of the device are equipped with a powerful domestic or marine self-priming vortex pump, which provides a system pressure of 0.7 MPa or more. Membraneless pumping stations are primarily intended for water supply of two-story private buildings with an area of more than 200 square meters.
A feature of membraneless installations is that they have a special safety valve that provides pressure equalization, and, accordingly, a high-quality pressure will be guaranteed at any point of the tapping regardless of the calculated load.
How to choose the right hydrophore
To correctly select and calculate the power of such pumping equipment For a private home, the following factors must be considered:
- Location and installation conditions.
- Source of water intake.
- Unit pressure and volume.
- Device equipment.
Despite the apparent complexity, choose the right hydrophore every homeowner can. It is only necessary to take into account the data on the average water consumption and have an idea about the features of the arrangement of the water supply in a particular house.
First of all, it is necessary to decide whether membrane or membraneless hydrophores will be used. Accordingly, the choice of such a device will largely depend on the area of the house and the average water consumption per day. In the event that you choose pumping equipment for a small house where a family of 3-4 people lives, then an inexpensive membrane hydrophore will be enough. It is necessary to take into account the small and large debit of water in the house, on the basis of which the choice of specific equipment should be made.
Unit pressure and volume
Choosing the volume of the accumulator, must be considered first The average amount of water that is consumed in a home. Productivity is calculated based on the amount of water used per hour. For example, it has been experimentally established that a family of four per hour consumes on average about 3 cubic meters of water. But a large family who lives in a two-story cottage with an additional flow of water to a personal plot should calculate the system performance at the level of 8 cubic meters of liquid per hour.
Most models of pumping equipment used today in private homes are capable of pumping on pressure at a level of 1.7 bar, and a switch-off pressure indicator can swing up to 3 bar. Accordingly, it will be necessary to choose the correct valves, and the connection of such an assembly is carried out exclusively in full accordance with the instructions.
Water intake source
When choosing a hydrophore, it is necessary to take into account the source of water intake, which can be used as:
- Water pipes.
- Storage tank.
So, for example, to pump water from a well or a well, an exceptionally powerful water pump will be required, which will provide the necessary pressure in the system. But for the intake of water from a pond or reservoir, you can use low-power stations, which do not need to raise water to a great height.
Modern pumping equipment is characterized by efficiency, compact size and high performance. When choosing specific stations, it is necessary to familiarize yourself with the instructions for each model in detail, which will allow you to get all the necessary information on the maximum pressure in the system and indicators of water rise. Based on the information received, it will be possible to make a choice of one or another model of hydrophore and pumping station, to understand how it will work.
Location and installation conditions
Thanks to the compact dimensions of modern equipment, hydrophores can easily be placed in the utility room, on the terrace, in the bathroom and even in the kitchen under the sink. At the same time, choosing a specific model, it is necessary to take into account the noise level and correlate it with the installation site. For example, if you choose a pumping station, which will be located in an open kitchen-dining room, then you should give preference to quiet and compact equipment.
Installing a pumping station, you should remember about the requirements and standards that apply to water supply systems used in private homes. So, for example, the following should be considered:
- The minimum floor area is 5 square meters.
- Ceiling height - not less than 2.2 meters.
- The minimum distance from the wall to the hydrophore is 60 cm.
- The minimum distance from the pump to the wall is 50 cm.
The temperature in the room should not fall below zero, and all electrical cables, lamps and wires should have a high degree of protection against moisture.
In the event that the noise and vibration indicator of the station used exceeds the standards, then hydrophores are mounted outside the house, installing them in special concrete insulated wells. In this case, it is necessary to use polystyrene or other insulation, which will prevent freezing of water in the well in the winter season and the growth of mushrooms in the cellar. Otherwise, the hydrophore and pump station may fail, requiring expensive repairs.
Setting up pumping stations
Immediately after the installation of the hydrophore, it is tested and adjusted. It is necessary to run the unit at full power, while simultaneously checking the tightness of all connections: any leaks through pipes, connections and fittings should be completely absent. Otherwise, additional waterproofing is performed using sealants or other similar means.
Modern water pumps for a private house and hydrophores are easy to operate, so such installations do not require any additional settings. This means that there are usually no difficulties with how to adjust the hydrophore with your own hands. If necessary, you can reduce or increase the performance of the pump by turning the appropriate toggle switches and rings to adjust the device. The homeowner can connect and carry out hydrophore adjustment independently, without resorting to the services of professional installers, and, consequently, this will significantly save on access to specialists.
Modern hydrophores are reliable and easy-to-use devices that allow you to organize the correct water supply for a private house. The selection, installation and commissioning of hydrophore is not particularly difficult, therefore, every homeowner will cope with such work, having completely solved the problems with providing a private house with high-quality cold and warm water.
