Air Dryer Leak

Which one is the wet tank?
Sorry, been out of the loop for a few weeks. The wet tank is the first one after the dryer.
 
Hi I'm new to the forum but I'm having the same exact problem. New dryer, new governor, new purge valve. Builds to 130 then bleeds down to 100
 
Being as this is a four year old thread I am going to take liberty here.
We had a trailer where the valve was pissing out air. So my partner starts hammering on it as was the style with the old valves.
Broken pieces of plastic everywhere.
So I hook to the trailer and the valve is leaking and I start hammering on it. As was the style with the old valves. Broken pieces of plastic everywhere.
Had to call out a mechanic who told us don't hammer on these new valves as was the style with the old valves.
These plastic pieces of crap are expensive!:rolllaugh:
 
100 % is compressor !! I did the same you did and problem was the same !! So I try compressor ! There are two lines to the governor . One is to sense tank pressure . The other line is a signal line to the air dryer to tell it to purge or blow off when the tank pressure line is at 120 psi !! Good luck :)
