Water purging system

A new and improved water purging system comprising, in combination:

• a primary water line having a first end with threads for the receipt of a faucet constituting a source of water and having a second end with threads for coupling to a supplemental water line for communicating a flow of water to a water utilization device;
• an air tank for the receipt of compressed air when the system is in use and for expelling the compressed air into the primary line and supplemental line to purge the primary and supplemental lines of any water disposed therein after the water flow has been terminated;
• a secondary line having a first end coupled with the air tank and a second end coupled to a central extent of the primary line, the secondary line having a one-way check valve therein for the flow of air from the air tank to the primary and supplemental lines;
• and
• 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 including a housing having a cylindrical bore with an air piston reciprocally mounted therein, the turbine 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 turbine vanes for generating pressurized air for movement to the air tank, the turbine also having a one-way air valve to preclude the return of compressed air from the air tank to the turbine, the turbine also including an air intake valve coupled with respect to the bore on the side thereof remote from the turbine blades for adding compressed air to the air tank.
