jobsmart will not build any pressure at all
10 gal. Horizontal runs great will not build any pressure at all I've checked lines fittings pop off valve and cannot find any leaks
Dean, start by pulling the intake filter, and then feeling if the intake port is actually pulling in air when the compressor motor is running. If not, your first problem is the intake valve may have failed.
Then, see the troubleshooting section on the site map page, and follow the links to the pages about why air compressors run (even if they run great) but will not build pressure.
