Why install a Hot Water Pump?
The Watts Instant Hot Water Recirculating System brings convenience and savings to your home, giving you hot water instantly at every faucet or shower when you need it. This unique product connects easily to existing plumbing, saving up to 12,000 gallons of water per year.
How does it work?
This recirculating pump eliminates water waste caused by waiting for water to heat up. 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.

Step by Step Installation Guide

Step 1 - Installing the Pump
A pump with a built-in timer mounts directly on the hot water line from the water heater with 3/4" connections.
Step 2 – Installing the Sensor Valve
A patented sensor valve 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.
Step 3 – Installing Sensor Valve Kits
If one section of your home does not receive hot water, you will need to purchase a Watts Sensor Valve Kit for each hot water loop. For best results, the valve should be located at the faucet furthest from the water heater in each loop.
