The FSG2J24BP has a 40 psi to 60 psi pressure setting range activates an electrically driven water pump within a power circuit when the adjustable rising and falling thresholds are reached. What would cause this?? It sounds as if perhaps you are losing well prime back down into the well - could be a bad foot valve - or a leak in the well piping.Is the pump in the well or above ground? Jack, if the pump does not start at pressures below the cut- in point of 20 psi, the switch may be bad.

On 2016-07-02 by (mod) re: effect of too small a difference between pump cut-in and cut-out pressure on the control switch. The pressure tank filled to 61 psi (as read on the water pressure gauge and verified with the automotive tire pressure gauge per test 1) above),..."If you close a valve between the pressure switch and the tank, how is the switch sensing tank water pressure? Next, the water pressure tank was drained and refilled in normal use mode (by flushing a toilet) and the water pressure switch reverted to its troublesome ways of cutting-out near 55 psi. The Square D by Schneider Electric Pressure Switch can be used with jet pumps, submersible pumps and reciprocating pumps. After I did this I wanted to increase house pressure, thought I'll boost the air tank from 30 psi to 50 psi, then I pulled the pressure line on the jet pump to clean. I installed an RO system to replace an old RO that failed because of pressure (new permeate pump booster). Or use the SEARCH BOX found below to Ask a Question or Search InspectApedia. My pump controls (amongst other things) our shower and the ice maker in the fridge. NPSF internal fluid connection and screw clamp terminals. Instead it hovers around 55 psi despite several attempts at increasing (clock-wise) the differential setting. Adjusting psi on Square D Pumptrol switch [ 1 Answers ] My irrigation system requires the well pump psi to be set above 30 psi on the low end or else it drains the well. John: are we talking "pressure" - (measure when no water is running) - or "flow rate" (that normal people call "pressure" but is really flow rate in gpm) ?A poor cold water flow while there is good hot water flow means it's not a system problem but a valve that's partly closed or a pipe that's partly blocked somewhere in the system.Another possibility is that the switch you replaced was actually set to a higher cut-in pressure than you realized. Thanks. Adjust the Big Spring Nut #1. We replaced the air tank, pressure control switch, the run capacitor, and the start cylinder. Thank you. The pressure tank filled to 61 psi (as read on the water pressure gauge and verified with the automotive tire pressure gauge per test 1) above), at which time the 220v electric line safety switch (2 pole, single throw) on the nearby wall was turned off, which simultaneously turned the well pump off. My pressure switch reads 60 psi. The problem is that when someone is taking a shower the cut-in rating is to low so the pressure is down. Hence my suggestion of replacing all lines and fittings. Also as I was down at the well, and it was turned on their was some sloshing in the system as it starts and turns off. Any advice would be helpful. The increased tank size was recommended by a water treatment professional and the increased psi range is to meet the operating spec for an ozone device on the laundry cold water supply. Dan that sounds like short cycling to me.
