Pump Up the Volume (film) Pump Up the Volume is a 1990 comedy-drama film written and directed by Allan Moyle and starring Christian Slater and Samantha Mathis.
When the system pressure drops to a preset level, the jockey pump starts and charges the system back to normal pressure. In case of fire, sprinkler heads open and fire hose connections are utilized causing a rapid system pressure drop over and above what the jockey pump is capable of supplying. When the lower pressure limit of the main fire pump is reached, it starts up and provides the needed high flow for fire suppression.
