What is a Pressure Tank / Booster system?

Domestic water system consists of the pump and the pressure tank which is also called booster system. The pump will deliver water from water source such as water tank. Pressure tank creates water pressure in the domestic water system by using compressed air in the pressure tank. The water is pushed out of the tank to your home when a valve is opened or someone uses water in the house. When the water pressure in the tank drops below the preset pressure, a pressure switch is activated turning on the pump. The pump will refill the pressure tank till the upper preset pressure is reached. The combination of the pump, pressure tank and pressure switch ensures water flow through your home.

The pressure tank also acts as a water reservoir which allows water to be supplied from tank without always turning on the pump. The water pressure in the tank will cycle between the lower pressure point (start pressure / cut-in pressure) and the upper pressure point (stop pressure / cut-out pressure). Both the preset pressure points are set using pressure switch.

For example:

Start pressure / cut-in pressure: 20 PSI

Stop pressure / cut-out pressure: 40 PSI

The booster system will ensure that the water supply is constantly at between 20 PSI to 40 PSI.
