What is bleeding off?
^^^^^^^Five posts up, 3rd thing to check^^^^^^
I believe the check valve is actually the piece that screws into the tank. It lets air into the tank from the pump but it does not allow air to come back out of the tank through the unloader line. This is also a pretty standard part, you just need to know the thread size of your current check valve. Or you might be able to take the current check valve out, clean it then reinstall it.
There should be a short burst of air exhausted after the compressor comes to the high pressure cut out
It should not last more than 10 seconds or so
The pipe between the compressor and the tank should bleed off every time the compressor turns off. If the check valve in the tank is broken or just dirty and jammed open air will continuously bleed out of the tank through the unloader valve when the compressor is not running. You need to look at where the pipe from the pump enters the tank. That fitting is the check valve. It should unscrew from the tank after you take the pipe from the pump off of it.
Depending on the plumbing, the line from the pressure relief valve ties into the main lin between the comprssor and the check valve. On my compressor, the tie-in is at the check valve itself. If air continues to bleed, the check valve is leaking, Either stuck of dirty. If the air volume is low, it is most likely dirty, preventing complete closure.
Ah Ha!
There is a check valve. Missed it the first go round.
Thanks guys, that's next.
Hang in there, you will have a new compressor by the time we are done with you... you will have just purchased it one part at a time though!
