no pressure build up 10 gal portable jobsmart
10 gal portable jobsmart. Runs but no pressure.
Someone worked onit and I think replaced a small part with a release valve instead. Still doesn't work.
Do you know what valve went into the two way pipe? One screwed down to the cooper tube and the other had a fitting of some kind but my manual is useless.
I feel like its an easy fix.
We only use it to pump up tires, and always bleed it off afterwards.
I've looked at the gaskets and they seem to be in great shape also the intake filters are clean.
Hate to buy a new one yet. Any suggestions? thanks so much.
