unloader valve failure (Nope!)

I'm getting a constant hissing of air at the unloader valve site and the compressor is kicking on due to the air pressure loss. Is that due to failure of the unloader valve or some other cause?

Hello Steve. Have a look at the page on CHECK VALVES linked from the site map.

Your symptoms are those of a leaking check valve, not the unloader valve.

Cheers,
