New Pressure Reducing Valve Problem
Brand new Watts PRV works, goes to required pressure (50#) then slowly raises to 70# + which opens the relieve valve. It would seem that this is a classic sign of crud caught in the diaphragm, my bad for not flushing the new house supply line. Any tips on washing the crud out, have tried tapping it while flushing the toilet. Gonna try zero-ing the house pressure, turning the valve up to its highest, and with a faucet open open the supply line for max flushing.
Will monitor pressure closely while doing this.
Really don't want to field strip the prv so any hints would be appreciated.
