ABSTRACT:
A water saving recirculating system (10) for a conventional water supply system (100) wherein: a fluid coupling (14) and solenoid valve (15) are disposed intermediate the hot water feed line (106) and a first cold water feed line (102); a one way check valve (11) is disposed in the cold water supply line (101); and, a pump (13) disposed in the first cold water feed line (102) for reversing the fluid flow through the first cold water feed line (102); wherein, the flow of water through the hot water feed line (106) is diverted through the first cold water feed line (102) until such time as the temperature of the water flowing through the hot water line (106) reaches a predetermined valve.
