New pressure switch and check valve but Campbell Hausfeld WL604003 still bleeds air
Unloader valve bleeds all the time and the exhaust tube gets really hot
I have a Campbell Hausfeld WL604003. I have been following your troubleshooting guide. I replaced the entire Pressure Switch (which has a new unloader valve ) and then replaced the Check Valve. Still, the unloader valve bleeds constantly.
Your suggestions are appreciated.
