Merrill PRVNL757 3/4" x 3/4" No-Lead Pressure Relief Valve, 75PSI

Features:

• Recommended for all cold water system installations - to protect against damage to piping and pressure tanks.
• PRV's have a plus/minus 15% setting accuracy

Note: Merrill pressure relief valves may not reseat themselves after pressure relief. Manual disassembly and reseating of the valve may be required. All PRV valves are field adjustable - by removing the cap and turning the internal disk down to increase pressure.

Warning: ALL PRV, SSPRV, and PRVNL valves must be set at a minimum of 15 PSI above the typical high of the water system pressure, so valve chatter or rapid open and close will not occur.
