Water Pressure Tank Sizing Chart

Data based on a well rite water pressure tank.

Water pressure tank sizing chart. You will want to choose a tank with the lowest volume capacity that is greater than or equal to the total required volume. Once the pressure in the tank meets the 60 psi threshold pump cut out pressure the pressure switch will signal the water pump to stop pumping ceasing the influx of water into the tank. Larger tank sizes will reduce pump cycles extending pump life and saving electricity. With the water pump off the pressure in the tank will remain at 60psi until more water in the house is used draining the tank once again.

To select the minimum size tank count the fixtures inside and outside your home including showers appliances toilets etc and refer to the chart below. There are no disadvantages to having a larger well tank. By reviewing the chart below you can get a general capacity of water you will get out of a tank based on your cut in and cut out pressures. A pressure tank is an integral part of maintaining your well.

The normal pressure spread for cut in and cut out is 20 30 p s i. Pressurized well tanks extend the lifespan of your well pump by preventing rapid on off cycling of the pump and maintaining water pressure throughout your home. When choosing an internal bladder type water pressure tank take note of the operating pressure range of your well pump equipment. Notes to the wel rite water tank sizing chart.

See example below with this information in hand you can refer to the flexcon sizing charts below to select the proper tank for your application. Most bladder tanks work by turning a pump on cut in a low pressure and by turning a pump off cut off at a higher pressure.
