How much water is wasted waiting for water to warm up?
An average home has 125 feet of 3/4" pipe. 125 feet of 3/4" pipe holds 3.14 gallons of
water. If hot water is used 10 times per day, 31 gallons of water is wasted running the faucets/
shower to get hot water. In a year, this equals to 11,461 gallons of water. 25.2 million homes
waste approximately 300 billion gallons of water annually.
How does the Instant Hot Water
Recirculating System 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.
