ABSTRACT:
A water supplying system has a pneumatic tank storing water and confining compressed air therein. The pneumatic tank is adapted to be charged with water by a pump. The supply of compressed air into the pneumatic tank is controlled in such a manner as to maintain a constant amount of compressed air in the pneumatic tank. A pressure-responsive device is attached to a water service pipe through which the water is discharged from the pneumatic tank and delivered to faucets or the like. The pressure-responsive device has a pressure-responsive valve adapted to break the communication between the pneumatic tank and the water service pipe when the water level in the pneumatic tank has come down near the port of the tank connected to the water service pipe, and a pressure switch adapted to control the operation of the motor for driving the pump in relation to the operation of said pressure-responsive valve.
