Zurn Wilkins Lead-Free Reduced Pressure Principle Valve Assembly with Integral Relief Valve Monitor Switch

Note: Lay lengths different than Model 375MS

Ideal where lead-free* valves are required. Designed for installation on potable water lines to protect against both backsiphonage and backpressure of contaminated water into the potable water supply. Assembly shall provide protection where a potential health hazard exists. 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 375MS is ideal for use in mechanical rooms, basements and enclosures where undetected relief valve discharge could potentially cause water damage.
