Compressor pumps up past cut out. If an air compressor runs, pumps air into the air tank, the tank pressure reaches the normal cut out pressure setting level, and the compressor continues to run and the pressure continues to build, this is a real problem! Eventually the PRV will let go, and the tank pressure should vent.
