Hi Steve... I'd have removed, cleaned and repaired the check valve if the air compressor was leaking air from the unloader.

If the check valve had failed closed, the back pressure build up would likely have stalled or bogged down the compressor motor. You say yours runs fine.

So, find the air intake and feel if it is pulling air in. Removing any intake filter, if it results in the pressure building to cut out, would indicate that it was the intake filter that was plugged. Probably not in your case, but worth checking.

Pop on over to the sitemap page, under troubleshooting, and follow the link to the page about why air compressors run but don't build pressure.

After reading that page, post a comment here if you have more questions, OK?

Oh, and it's NO CHARGE for my advice.
