At high pressures the risk is a burst pressure tank and injuring someone nearby. But with these readings I have bad adjustments. Is the continuously running pump under the sprinkler scenario a harmful condition? This article series also includes information on how to adjust building municipal or community It reveals the parts of the circuit as simplified shapes, and also the power and also signal connections in between the gadgets. pressure connection. is there a problem with my pumptrol (normal 20/40) while it is running on 20/32 only? Under a normally set pressure switch, the pump should come on at 30 PSI and shut off at 50 PSI. On 2015-11-24 by (mod) can the spring in the adjustment nuts be replaced? He adjusted the pressure with the bigger nut as explained in the WEB site, so now the cut-in pressure is about 32 and the cut out is about 58-60. This water pump pressure switch is designed for control of electrically driven water pumps. The differential nut is the 3/8-inch nut that adjusts the smaller of the two springs in Models FSG, FYG, FRG, and Type G switches. What might be the cause of this problem? I meant the flow rate. My problem is that the pump,turns on what the hunter controller tells it to but shuts down right away. The well pressure tank was upgraded from Well-X-Trol WX-202 to WX-203 and the Square D pressure switch was upgraded from 30/50 to 40/60 w/ automatic low pressure cut-off. It is a new switch doing this and the old switch had been suffering from the same problem. The pressure gets down to less than 15 and the pump still has not pumped. It normally turns on and off by means of a Hunter controller. The units cuts in about 26-28 psi. I have a water pump that is used for my lawn sprinklers. thanks.if I increase just the cut on pressure, does that mean I risk short cycling and therefore pump life? Pump Pressure Switch Pumptrol™ Nut Adjustment Sequence. Square D by Schneider Electric 9013FSG2J24M4 Air-Pump Pressure Switch, NEMA 1, 40-60 psi Pressure Setting, 20-65 psi Cut-Out, 15-30 psi Adjustable Differential, Low-Pressure Cut-Off 4.6 out of 5 stars 289 . Any advice would be helpful - Mark 8/31/11, We are losing water pressure at any/all faucets/toilets/etc randomly- water will be running fine, and then it will slack off to nothing, then within 30sec to 1 minute, water will come back one and be fine. To keep the ice maker working I have to have high pressure (50 ++). Adjusting the differential will only adjust the cut-off pressure. Thomas I wonder if you carried the adjustment too far. Shawn, if a pump always comes on immediately when you open a faucet and shuts off when you close the faucet, your water pressure tank is water logged - it's lost its air charge. It tracked the water pressure gauge correctly, so we now know that gauge is OK. 2) There is a ball valve on the 1/4" pipe between the water pressure switch and the tank T. That valve was turned off once the cut-in took place. The NEMA 1 enclosure has a 1/4 in. The FSG2J21BP has a 30 psi to 50 psi pressure setting range activates an electrically driven water pump within a power circuit when the adjustable rising and falling thresholds are reached. Is the low pressure cut-on set too low? As it reacts to that pressure change in the system the pressure switch generates or drops an outgoing signal that is used to initiate another action.

On 2016-09-28 16:07:26.366930 by stuart renouf. - BigEd 7/16/11, The pump will not come on. I'll turn the pump off and back on then the pressure will come back up and if it runs about a couple of minutes it will do the same thing again. 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. When that happens the pump will simply run continuously. It causes me a lot of trouble when I fill large livestock tanks,can I modify the switch to eliminate the low pressure shut off feature or must i replace the switch. When the plumber installed the new pressure switch 30-50 I asked him to adjust the pressure and that is what he did. Open a water faucet and watch the pressure gauge. anybody can help us fixed our problem, is it the adjustment regarding pressure switch please advice us what to do.thank you, Hi! On 2016-09-28 by (mod) re: pump runs continuously - may have damaged pump. thanks - Mike Jones 8/22/11. There is little room left to compress the differential spring any further. - pumpwontstop 6/17/11. But the pump running continuously and never delivering cutoff pressure is something else _ such as lost well water flow rate or a well piping leak or someone has lest a faucet open in the home. - Gene Doverspike 12/6/11. If you have no air in the system the switch should work normally. It's suitable for all pumps including jets, submersible, and reciprocating. So not all pressure switches will behave identically. InspectAPedia tolerates no conflicts of interest. I believe I have a short cycling problem. A wiring diagram is a streamlined conventional photographic depiction of an electrical circuit. That can happen for a variety of reasons like loss of water in the well, a well piping leak, water running somewhere that you didn't realize, a pressure switch set too high, or a damaged pressure sensor component of the pressure control switch. Probably a mistake. Indeed the pressure tank air charge is not what determines house water pressure - that's controlled by the pressure control switch, as you observed. JohnAs long as the pressure is under 70 psi you are probably below the limits of your water pressure tank - though you should check that by taking a look at the tank's installation manual (or give me the brand and model and we'll help research it).You should also have a pressure relief valve installed at the water tank tee.The article PRESSURE SWITCH NUT ADJUSTMENTS describes how to adjust the large and small pressure switch nuts, what each does and how they relate. My well is not quite a year old, we have always had plenty of water and pressure. My tank is in my house (pier and beam) and about 40-50' from the well so meaning my water tank is probably 3' above the level of my well if that has anything that could be a problem. In principle certainly.However the replacement kits I've seen didin't include that part; you may have to buy a whole new switch (typically under $30. I too tend to look first at work that was just recently done, or what was just changed, when debugging a building problem that has just shown up.I tend not to start by blaming the pump, though there could be an indirect cause there: if the plumbing changes increased the water usage rate or the rate at which the pump was asked to operate, a pump motor that was overheating (failing) might on occasion turn itself off on thermal reset then reset and begin again automagically.
