This procedure is detailed in the installation manual and should be performed during every installation, as individual system pressures and tank pre-charge can vary. Q: What is the correct procedure to set the pre-charge in a well tank?Ī: With the pump off and the tank empty of water, the compressed air pre-charge should be adjusted to 2 psi below the pressures switch cut-in pressure. This cycle allows the pump to run intermittently, rather than continuously allowing time for the motor to cool. When the tank is nearly empty, the well pump activates, refilling the tank and repeating the process. As fixtures are operated, the tank supplies water to meet demand. During operation, the pump fills the tank, providing a reservoir of pressurized water. This air charge provides positive pressure, allowing the tank to fill and empty with water usage. A well tank provides a buffer of stored water, protecting the system and reducing energy use.Ī: Water Worker well tanks utilize a flexible diaphragm, that separates stored well water from a compressed air charge.
Without supplemental storage, small water uses like running a faucet or flushing a toilet would cause rapid pump cycles. Most pump motors are designed to run for a minimum of one to two minutes to prevent over-cycling and potential failure an expensive repair or replacement often costing thousands of dollars. A: All well systems require pressurized water storage to reduce pump cycling.
