Pump Pressure Tank Sizing

Properly sizing a water pressure tank ensures that the run time on the water pump is kept at a minimum.

Pump pressure tank sizing.

Because the pressure tank is a core component of the entire well system responsible for regulating pressure and for easing the workload of the well pump the importance of selecting a the right well pressure tank cannot be overemphasized. A 10 gpm pump needed a pressure tank that holds 10 or 20 gallons. Sizing a water pressure tank properly keeps the amount of run time to the water pump held to a minimum. To properly size your flexcon well tank you will need to obtain the following information.

A larger pressure tank can often be a good way to extend the life of your pump and electric motor provided that you have enough space to accommodate a larger tank and where the flooring can hold the additional weight. Old pressure tank sizing method in the past pressure tanks were sized to store at least 1 or 2 gallons of water for every gallon per minute the pump can produce. The pump delivery rate in gallons liters per minute gpm lpm the recommended minimum running time of the pump the minimum cut in and maximum cut out system pressure parameters. This should not be confused with tank volume for example a pre charged tank with a tank volume of 20 gallons has only five to seven gallons drawdown capacity depending on the cut in cut out on.

A pressure tank is an integral part of maintaining your well. A 20 gpm pump needs a tank with 20 to 40 gallons of storage. If you re installing a new water pressure tank or replacing an old one you can determine the size for optimum water pressure and pump performance using online calculators.

Tank drawdown capacity is the minimum amount of water stored and or delivered by the pressure tank between pump shut off and pump re start. Almost 2 3s or more of a tanks. The more a pump must run the more wear and tear occurs to the pumping mechanism and the electric motor. Selecting a poorly made pressure tank may result in more troubleshooting scenarios than necessary.
