So for some time now the air pressure in my two tanks drops slowly,than I had two valves sticking open! So I have been spending the last two days removing the valve manifolds & cleaning the valves & replacing the check valves. I still have to replace 4 check valves at the input & outlet of the tanks!! Hope this stops the problem!
I had a dump stick open one day in my neighborhood. It was a sub 32 degree day, once I stopped and cycled for a few seconds, it never did it again. I did clean all of them that day, but didn't find anything suspect. Near as I could tell, it was ice. It's the one thing that has made me think about getting check valves, but I don't run a water trap or check valves. I do drain my tank routinely...
I run two water traps ( one each side of one tank, the two are tied together), & check valves from Mc Master Carr! One of the check valves threw a seal.it was whole in the fill valve causing it to stick open! I had a bad presser sensor also ,had a spare, new design, need to get 4 more of these befoe no longer can get them!!
