MOEN 2581 M-PACT Posi-Temp 3-Function Diverter Rough-In Valve with Stops, 1/2" CC/IPS

The MOEN 2581 combines a Posi-Temp pressure-balancing valve and integrated three-function transfer valve in one rough-in body. It controls temperature while directing water to either of two showering devices independently or to both simultaneously. The four-port valve uses 1/2-inch CC or IPS connections and includes service stops.
