ABSTRACT:
A water saving system for preventing the waste of water which falls below a predetermined temperature, which system includes a recirculating pipe line extending from an outlet faucet back to a heating device and which system is appropriately controlled thermostatically by a series of temperature sensing devices. The system includes a solenoid control valve which prohibits the delivery of water, which is below a predetermined temperature but which is appropriately controlled to be opened when the water in the delivery line is sufficiently heated. The system further includes a pump, which is energized to recirculate cooled water back to a heating source and which pump is de-energized when the water in the delivery line is at the desired predetermined delivery temperature.
