Set your desired pressure on the CO2 regulator to keep popoff valve closed, if unit senses greater pressure than the regulator set point or a pressure spike it opens automatically. Making it safer to set your boat down on the top end there is an override button. The unit bolts in place of the hand hole cover.
Requires machining of suction housing bore.
