Gauge will eventually read about 15 psi and a small amount of air will vent when I open the relief valve, but that's it. On the other hand, if there is any hole on any part of the compressor, you have to find that out and fix it. When it gets to the cut-out pressure, we expect the air compressor to stop automatically. First of all, empty the tank by draining all air out. 15. see all. Usually, your air compressor will not build pressure if there is something wrong with the pump. Compressor Will Not Build Pressure In some cases, a compressor will run as though it is functioning properly when, in reality, there is a problem with compressor pressure. It's this unsteadiness that limits pressure build in compression tanks. When there is a problem with the gasket, it cannot keep the airs separated.
