So, I finally installed my brand new propane system, with alarms, solenoids and all. And the first pressure test reveals a slow leak.
I took the entire system apart, testing shorter pieces until I am left with just a tank, a pigtail hose and a regulator (plugged on the other end). The leak is still there. So, I bought a new pigtail and a new regulator - and changed over and resealed all the connections - same result.
Anyone dealt with that before? Could it be the tank itself? How the hell do i find it? Soap and water failed miserably, perhaps because the leak is very slow (I get down from 175psi to 120psi or so in 24 hours). Ideas would be very welcome.
