Sears 919 152920 Check Valve Problem
(Fort Smith, AR)
I have a Sears (Devilbliss) 919 152920 compressor. The compressor starting taking a long time to build up pressure and after reading articles here, I replaced the piston and sleeve which solved that problem. After starting the unit and letting it shut off, air started leaking from the unloader valve which indicates a bad check valve. Unfortunately, the check valve for that model has been discontinued and I can't locate one anywhere. Is there a retrofit or superseded part that will work? Would a generic check valve installed at the end of the pressure line work since the existing check valve is open. I hate to trash the compressor since I've already invested in the rebuild. Any help would be appreciated.
