WellMate fiberglass pre-charged 30 gallon bladder well pressure tanks # WM9. Equivalent in drawdown to a 82 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.

Questions & Answers

Drawdown refers to the amount of water that evacuates the tank before the pressure switch will activate the pump. Drawdown is a affected by the pump, the size of the tank and the pressure settings that govern your water system.
All WM WellMate tanks carry a five year limited factory warranty for potable water residential installations and 2 years for non-residential installations.
No, unfortunately there are number of factors that can contribute to a failed tank and the only factor that WellMate can insure is the tank.
The pressure switch communicates with the tank and the pump. The pressure switch monitors the pressure inside the tank and activates and de-activates the pump when cut-in and cut-out pressures are reached inside the tank.
Your tanks should be pressurized to 4 PSIG less than the cut-in pressure setting (for example, if your pressure settings are 30/50, then you cut-in pressure setting is 30 PSIG and your tank should have a 26 PSIG pre-charge).
To check the pressure in the air cell, the power supply to the well pump must be turned off and the water must be drained from the pressure tank.. With the pump turned off and the water drained from the pressure tank a standard tire gauge can be used on the valve stem at the top of the tank. The pressure in the air cell should be 4 psi lower than the pump cut-in pressure.
