Well pressure tank size needed. Selecting a poorly made pressure tank may result in more troubleshooting scenarios than necessary. Your flow rate is how many gallons per minute your pump produces. Most private home well systems operate between 30 pounds per square inch psi and 50 psi. Most pressure tanks are evaluated by their draw down capacity which is how much water can be kept in the tank before the pressure is at a point low enough to turn the pump on again.

To properly size your well pressure tank you need to know three things. Desired run time of the pump 3. Water pressure tanks store water that s pumped from a well and dispense water under pressure when you use faucets and other fixtures. Minimum runtime multiplying the flow rate by the minimum runtime of the pump will give you the drawdown capacity.

Naturally the larger the pressure tank is in size the more water it can hold without re engaging on the pump. The pump turns on when the system reaches the low pressure cut in and off when the high pressure cut in. It s important that the size of a tank is adequate for your. To determine the proper size of the pressure tank there are three factors to consider.

Understand that most pressure tanks are rated by the draw down capacity. Draw down capacity is the amount of water that is stored within the tank before the pressure is low enough to turn the pump back on.
