How does the Instant Hot Water Recirculating Pump Work?



A pump with a built-in timer is installed on the
hot water line from the water heater (Fig. 1). A patented
sensor valve (Fig. 2) opens when the water on the hot
water side cools and pushes the cool water back to
the water heater. As the temperature in the hot water
line hits 98º, the valve closes.


Some homes are designed with multiple hot
water loops, one per floor, etc. If one section of the
house does not receive hot water, you will need to
purchase a Watts Sensor Valve Kit (Fig. 3) for each
loop. For best results, the valve should be located at
the faucet furthest from the water heater in each loop.
