You will need
- - pump pressure boosting;
- - automatic pump station.
Causes of low pressure in the water can vary from partial blockage of pipes of salt deposits to the location of the apartments on the upper floors of high-rise building. In that case, if utilities are unable or unwilling to correct the situation, you can try to solve it yourself due to the installation of additional pump.
First, assess how the water comes into the apartment, depends on the choice of pump. If it flows from the tap, but the pressure is always small, you need to install a pump to increase the pressure. If it did not, but it is on the floor below, you will need a self-priming pumping station.
The pumps increase the pressure hit in the water at the entrance to the apartment. It can work in two modes, automatic and manual. The first option is preferable – the pump is switched on when the valve opens, and maintains the desired pressure. As soon as you close the valve, the controller will shut off the pump. In manual mode, it operates forcibly, without automation. This mode provides constant water pressure even in low pressure, but requires disconnecting the device after the cessation of water analysis. If the water in the system is not all, the pump can burn out. In automatic mode, the electronics will switch off the pump when the pressure drops below the minimum.
Install automatic pumping station consisting of a pump, usually centrifugal, a hydraulic accumulator, control unit and pressure gauge. She has sufficiently large dimensions, so to install it you will need to find a place. Thanks to the hydraulic accumulator with elastic membrane in the system is always maintained at the appropriate pressure. When it drops below the nominal pump activates and pumps water to the battery. Once the pressure reaches the maximum level, the pump turns off. The check valve prevents loss of water back to the water.
Note that pumping stations work well in private homes, but in a multi-story building when installing them can be a number of problems. In particular, when the water pump starts to drain the air through the open valves from the neighbors that at least will lead to a situation where the cranes you will have to "spit" a mixture of water and air. When a large amount of air a centrifugal pump will cease to operate, to run it you would have to fill the system with water. Therefore it is better to consider the first option – the installation of a pump to increase the pressure. If the water doesn't rise up to your floor, require utilities address this issue.
A third factor regulating the pressure of the water is the height of the building. Water has its own weight, and in order to raise it to the top, at the bottom of the pipe is necessary to create a sufficiently large pressure. To raise water to a height of one floor of an ordinary apartment house, you need to have a pressure of 0.27 kg/cm2.
For example, a submarine, submerged at 100 m under the water under pressure equal to 10 ATM (above atmospheric), which corresponds to the pressure inside the steam boiler of a steam locomotive. Thus, each depth below the water surface corresponds to a certain hydrostatic pressure. Submarines provide pressure gauges that measure the pressure of the sea water; this helps to determine the depth of the dive.
Advice 2 : How to increase water pressure
If insufficient water supply pressure water, install a special charge station. In the case of uneven pressure, for example, reduce it with increased drinking water, select a special accumulator. In the General case, the pressure of water can be increased by increasing the height of the column above the tap.
You will need
- You will need a pumping station, a pressure tank with an extra capacity water tank.
The increase in the pressure of the water in the water. To raise the pressure of the water in the pipes, check the pipes if they are clogged, change them. If not the pipes, install a pumping station. For this cut the piece of pipe immediately upon entering the water pipes in the apartment. Cut the threads on the scraps of pipe and insert a pump. For normal operation of the machine it is necessary that the pressure in the water was not less than 0.2 ATM., in this case, water power station will be enough to maintain normal pressure. Below the station operates in the standalone mode, install pressure gauge and adjust it to a certain value. For example, the station will activate only when the pressure in the water main falls below 0.8 ATM. When using the station, note that when enabled, the neighbors , the pressure of the water may drop to critical values.
In that case, if the water disappears altogether, use the system with accumulator. He is a reservoir in which is located the sensor of level of waterthat is triggered if the level of water inside the tank falls. To the tank connected to the pump which turns on when you open the tap. The system continues to work as long as there is water in the tank. Once in the water again the water tank is filled independently. In front of the entrance of water be sure to install the filter. In the selection of the tank expect the water in it should be fully updated within two days.
The increase in the pressure of the water in the tank. If there is a system of the crane capacity, in order to increase the pressure of the water in the tap, raise the level of water in any way. The easiest way – just add water into the tank. The higher the liquid column, the more pressure. Second option: raise the reservoir elevation, connecting it with a tap flexible tube. Pressure water will be directly proportional to the liquid level rise.
Advice 3 : How to increase the pressure in the apartment
Very often tenants of apartment buildings that occupy the top floors complain of too low pressure tap water. Because of this trouble may stop working washing machine or water heater, and in the economy is felt a number of inconveniences.
You will need
- -storage tank;
- -the pump.
First of all, try to appeal on this issue in the offices of those public utilities which deal with water issues. The existing standards , the pressure of the water in the taps should be sufficient for operation of appliances. Therefore, the consumer has the right to file a complaint.
If the appeal to the municipal services did not help, and the water pressure still remains low, try replacing the tube at the same, but with a slightly smaller diameter.
To solve this problem will help the installation of the storage tank with the pump. Today you can buy special models of pumps which increase the pressure of cold and hot water. Pump designed for hot water, equipped with a fan for cooling. With this design, it is suitable for installation on the riser hot water, the temperature of which is up to 80 degrees. Operate these pumps manually and automatically. The most convenient to use is an automatic pump.
The pump works in the following way: you turn the water on, it flows very slowly. Immediately automatically turns on the pump, and the pressure increases by 1 atmosphere. This allows you to begin the process of operate the washing machine or water heater.
If the apartment has been too low pressure of air during ventilation, it is necessary to blow out air vents using a vacuum cleaner. To check the operation of the ventilation system, attach to the grate sheet of paper, cut fringe. If ventilation is working properly, the sheet should "stick" to the grid. In this case, to improve pressureand air can be embedded in the vent is a simple exhaust fan. The house is quite possible to install additional fans and air conditioners.
