My air compressor, a 20 year old Champion VR5-8 leaks air out of the rubber hose used to release pressure from the pistons after the power shuts off.
The hose connects to what looks like some kind of diaphragm body (second picture) and dangles down along side a thin copper tube coming from near the bottom of the tank. the air coming out of the hose is easily detect able though I can't hear a hiss, but when I put my finger over the tube it builds pressure and pops off.
I read a lot of posts about check valves being responsible for likes, but I am not that familiar with large air compressors like this. The parts list mentions, I think, three check valves. How do I know which valve needs to be replaced? I am assuming that the air from the tank is either leaking back through the main inlet line through the pistons, and through the diaphram thing back to the hose, or it could be coming out of the thin tube connections to the diaphragm thing and out from there.
Suggestions?
