Abstract:
1. Domestic water well pressure maintenance assembly, comprising: a pressure maintenance valve having an inlet side and an outlet side; a pressure tank in fluidic communication with the outlet side; a pump in fluidic communication with the outlet side; a pressure switch, wherein the pressure switch turns the pump on when a pressure in the outlet side is at a cut-in pressure and off when the pressure is at a cut-out pressure; and a calibrated bypass, wherein, when the valve is closed, fluidic communication between the inlet side and the outlet side is provided solely by the calibrated bypass, wherein the size of the calibrated bypass and the size of the pressure tank are adapted and constructed to permit a flow rate between the inlet side and the outlet side that will fill the pressure tank in a time interval less than twice the time required to pump a volume of water that will dissipate heat generated by the pump when it is turned on.
