A check valve is provided for use with a compressor system having a pump and a storage tank, the check valve including a housing including an inlet connected to the pump, a tank port in fluid communication with the storage tank, and a bypass port, all in fluid communication with each other, and with a chamber. A reciprocating piston is disposed in the chamber and has a heavy spring at one end, and a light spring at the other end. The check valve is constructed and arranged so that pressurized air is accessible from the bypass port prior to the storage tank being fully pressurized.
