I redid the connections from my main line before they hit the house about 3 years ago or so. I have a 1 1/4" feed that I have split (T) to the right it goes to irrigation and has its own Pressure Reducing Valve set to approximately 70PSI which seems fine, and to the other side before it hits the house it runs through another Pressure Reducing Valve set to approximately 60 or so, I believe. Each has its own ball valve to shut off independently. I have a hose bib on the irrigation side, and a pressure relief valve on the other. The gardner brought to my attention that the pressure relief valve before the line hits the house has been leaking as the area under the setup is wet. I started by replacing the pressure relief valve but that did not solve the problem. I notice that when I let water out of the pressure relief valve, it drops the pressure to about 60PSI or so, and the over the course of 10 minutes or so the pressure is back up to about 100-125 and it starts leaking again. I thought this valve does not open until the PSI gets to 150 so I am a bit confused. Maybe have been having 150 to the house since the Pressure Reducing Valve has failed. I have never adjusted this PRV. Would that be the first step, or does it seem as though water leaking out within 10 minutes or so suggest a seal that is shot? I do notice that the adjustment nut and bolt on the pressure reducing valve seems rusted? How difficult are these Pressure Relief Valves to service for a non pro to do? What part is the likely culprit, and how difficult is it to get to it? Any help would be appreciated. I cannot call Zurn until Monday, so any feedback would be welcomed. Thanks.
