Model 975XLMS (Sizes 3/4" - 2")

Reduced Pressure Principle Assembly w/ Relief Valve Monitor Switch

In the event of a backflow condition, the relief valve closes an electrical contact on the MS switch, signaling that a possible relief valve discharge may be occurring. The 975XLMS is ideal for use in mechanical rooms, basements and enclosures where undetected relief valve discharge could potentially cause water damage.
