Unloader valve

by Jeff Marz

I thought it was a bad pressure switch or relief valve that was causing the compressor to bleed off air continually until it restarted.

So I replaced them both and it still does it (bleeds off air until it restarts).

Now I see that it is bleeding through the unloader valve. How can I make it stop doing this .....it is driving me crazy.

Jeff, don't go crazy. Clean or replace your check valve.

Here is more information on the problem you are seeing.

Cheers,
