WebThe 32 gallon capacity is the physical volume capacity of the tank. This diaphragm tank will perform to the same specifications of a standard 82 gallon tank without a diaphragm. With a cut in/out pressure setting on the water pump of 20/40 PSI, the tank can put out 11.2 gallons before the pump turns on, or it can drawdown 11.2 gallons. WebThe drawdown is 7.5 US gallons (20/40 PSI) or 6 US gallons (30/50 PSI). The tank is factory pre-charged but the pressure should be adjusted before use to 18 PSI for use with a 20/40 PSI pressure switch or to 28 PSI with a 30/50 pressure switch. View More.
