PRV are set at 75 psi or 100 psi - adjustable from 75 to 150 psi. PRV have a +/- 15% setting accuracy. Merrill Manufacturing pressure relief valves may not reseat themselves after pressure relief. Manual disassembly and reseating of valve may be required. All PRV, SSPRV, PRVNL, PRVHD and PRVHDNL valves must be set 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. All PRV valves are field adjustable - but removing cap and turning internal disk down to increase pressure..

If it is ever triggered for even a split second by water hammer effect or anything they completely stop working and start leaking water at a rapid rate which In turn causes the pump to run continuously because the water is recirculating through them after they fail. They advertise them as being adjustable, but say in their "fine print" that if you do it voids warranty. They are useless for the only application they would be practical for if their is the slightest chance that it will be needed. They are for looks only.
