Here is the background; we have an old Weil McCain boiler that was oil converted to natural gas quite a few years ago then suddenly it tripped the prv and snapped the drain pipe connected to it. Upon inspection the old pipe from the prv to floor was full of corrosion and blew apart at the weakest point which was the threads at the prv itself so I replaced the prv (30 psi) and it tripped again so after more inspection I found it had the wrong fill valve so we replaced it also but now it's still releasing so onto the compression tank. We removed the tank and had it tested by adding air and submerging and it passed the test. So apparently since the prv drain piping was blocked with corrosion I'm thinking the problem existed quite a while ago. also there is an old water heater connected but the potable side has been disconnected for years and no longer needed. I'll try to post pictures or video.
Any thoughts??
