With respect, if it won't go over 20 PSI in the tank, and it won't stop running, then I'm afraid that it "doesn't run great!"

You are not giving me very much information to help diagnose your compressor problem.

Tell you what. Did you get a chance to follow the link on the "will not build pressure" page that says "I've just added a page that summarizes many of the answers about why a compressor won't build pressure. That page is right here?"

Maybe you could check it out. It itemizes many of the reasons a compressor won't build pressure, and might either help you diagnose your compressor problem, or enable you to provide more information about the problem so I can help you figure out what's what?

Cheers,

Bill
