Key features
Replacement Sensor Valve
Designed for use on branched hot water lines coming from the water heater, the Watts Premier Replacement Sensor Valve can serve as either a replacement valve or in heating spaces where an additional valve is needed.
Integral Component
The sensor valve is an integral part of the hot water recirculating system; it opens when the water on the hot water side cools, pushes the cool water back to the water heater, and closes when the hot water line hits 98 F.
Simple Design
This replacement sensor valve has a simple design that makes it easy to initially install as well as replace when needed. This product only comes with one valve and is compatible with both 500800 and 50080 Hot Water Recirc Pump models.
Indoor Only
Suitable for use with all types of pipes, this sensor valve is meant only for indoor use on standard tank water heaters in residential buildings; it is not compatible with tankless water haters or for outdoor applications.
