To set the accumulator pressure do the following. Turn off your pump at the electrical supply Open a tap to allow system pressure to be zero Pump up or let down the accumulator until the pressure is approximately half of the pump pressure-switch trip setting. Close tap, re-enable electrical supply. Test pressure yearly under conditions described above. -- Richard
