Watts 500803 Instant Hot Water Recirculating System (bare tool) (open box)

Watts Premier Hot Water Recirculating System provides water to your faucet or shower instantly, eliminating water waste caused by waiting for water to heat up. This pump offers quiet, maintenance-free operation and includes a programmable timer that can be set to activate the pump only when you need it or set it to run 24-hours a day.

The device uses the pump at the water heater and a patented under-sink sensor valve to create a pressure differential. The pressure differential allows the cold and cool water in the hot water supply line to bypass into the cold water supply line at a low volume through the thermostatically controlled sensor valve, keeping the water in the hot water supply line at a “no-wait” temperature throughout the home.
