Extremely quiet and energy-efficient, the Watts Hot Water Recirculation System utilizes thermal bypass technology to instantly supply hot water in about 15 seconds at every faucet or shower when needed. The sensor valve opens when the water on the hot water side cools, pushes the cool water back to the water heater, and closes when hot water line hits 98°F.
Operating on 120V, the system easily installs into existing plumbing without the need for a return line or additional electricity under the sink, and once installed requires no maintenance. Includes everything you need for installation: heavy-duty stainless steel pump head in aluminum housing, 10 ft cord, 2 adapters with rubber washers, valve mounting screws, and two 12-inch supply lines. This product measures 6.2″ x 6.0″ x 5.0″, weighs 8.4 lbs., and is highly resistant to stain and corrosion.
