  
WellMate fiberglass pre-charged 20 gallon bladder water pressure tank # WM6. Equivalent in drawdown to a 42 gallon galvanized atmospheric tank. Tank drawdown is the amount of water that can be removed from a tank, when it is full, before the tank pressure drops and the pump is turned on to refill the tank. A larger tank gives more drawdown which means that more water is available before the pump is needed.
