A one-touch Compressed Air Foam System (CAFS) is provided that allows for a simplified user interface and simplified user operation. The user interface allows the CAFS to activate upon a single press of a single button. An electronic controller checks that several CAFS device parameters show that the CAFS is capable of operating. The controller gathers the device parameter data from a diagnostic system present in the CAFS that gives data pertaining to whether water is flowing, whether foam concentrate is present in the system, whether foam is flowing, and whether the temperature of an air compressor is within a safe range for operation. If the above device parameters are found to be in condition for safe operation of the CAFS, the controller will start and maintain operation until either one of the above falls out of tolerance or the user initiates a shut down of the CAFS.

An apparatus and method for releasing pressure and draining a high pressure water system includes a valve comprising a valve body having an inner cavity for water to flow therethrough, an inlet opening and an outlet opening in fluid connection with the inner cavity, a valve seat assembly comprising a first biasing member exerting a force against a valve plunger cooperating with a seal to thereby substantially close the valve at or above a predetermined system pressure, and an override comprising a manual activator having a second biasing member and a cooperating member positioned to transmit to said valve seat assembly a force applied by an operator, to thereby manually open the valve when pressure exceeds the predetermined system pressure.
