ABSTRACT:
A water purging system is disclosed. The system includes a primary water line having a first end with threads for the receipt of a faucet constituting a source of water and a second end with threads for coupling to a supplemental water line adapted to be purged of water after usage. An air tank is provided for the receipt of compressed air and for expelling the compressed air into the primary line and supplemental line after use of the system. The secondary line has a first end coupled with the air tank and a second end coupled to a central extent of the primary line. The secondary line also has a one-way check valve therein for the flow of air from the air tank to the primary and supplemental lines. Further included is a turbine having a first end operatively coupled to the air tank and having a second end operatively coupled to the primary line. The turbine includes a housing having a cylindrical bore with an air piston reciprocally mounted therein, the turbines having water turbine vanes in the primary line adapted for rotation upon the flow of water therepast with a linkage coupling the turbine vanes and the air piston to reciprocate the air piston upon rotation of the vanes for generating pressurized air for movement to the air tank.
