One of the most important components of a well pump system is its tank. The tank ensures that the pump will not be overworked by over-frequent starts and stops. A properly chosen and installed tank, together with the right well pump, will help provide smooth, consistent water pressure.
What is a precharged tank? Try to envision a steel tank with a trapped, air-filled balloon. As water is pushed into the tank by the well pump, the "balloon" is compressed. When the pump switches off at it's high pressure limit, the pressurized air is pushing against the water. When water is used, the "balloon" expands and pushes the water out of the tank. In the diagram below, the diaphragm serves as the balloon. By prepressurizing a tank, we are able to get more gallons from each pressure cycle in your pump systems than in a plain tank. Good precharged tanks need minimal inspection and upkeep.
