Nice mixing valve for homes with 1" hot water mains
Installed this on a home wanting reduced and controlled temperature at all outlets while maintaining the primary boiler hot water tank at 140 degrees. This home had a hot water recirculation circuit and only two openings on the tank one 1.5" for cold and one 1.5" for the hot supply. The hot water recirculation pump did not include a check valve and we found that cold water would back feed whenever hot water was in high demand. Problem was solved by ordering and swapping out the old pump with a new Grundfos UPS 22-35 stainless pump with internal check valve to prevent the back feed which was diluting the hot water at showers and tubs.
