Hydro – Pneumatic system designed by us consist of a smallish steel tank, divided into two compartments by a rubber membrane, this system is connected to the water supply line, which in turn gets pressurized. Whenever someone opens a tap, water flows out, and the pressure in the hydro-pneumatic tank drops, which causes the pump to be switched on again, thereby maintaining pressure in the line while supplying the required quantity of water to the outlets.
