thank you for answering me fast. See the article titled WATER TANK AIR, HOW TO ADD (links at the ARTICLE INDEX the bottom of this article )You might also have a problem of sediment clogging at the pressure sensing switch and gauge both - even if you replaced the switch if its mounting tube were clogged the problem would continue. What should I do to get the pump to cycle properly? with low pressure shut off. My pump runs for 20 seconds then shut off. The NEMA 1 enclosure has a 1/4 in. If I remember I had a 20-40 pressure switch that was adjusted to 40-55 so that when taking a shower we would not notice the low pressure. Nov 2009. When the plumber installed the new pressure switch 30-50 I asked him to adjust the pressure and that is what he did. If the leak is between house and well then unfortunately excavation is in order.If the leak in the well pipe is in the well and is between the water surface and well top, you'll hear or even see water squirting out of the leak when the pump is running; if it's under-water you may never see it without pulling the line.All of this means that you start by determining that the leak is between house and well.Search InspectApedia for"find leak in well piping" to find our diagnostic article, Pump won't come on: I just changed the pressure control switch and it will not turn on by itself. A pressure switch is simply a device that reacts to the changing pressure in a system. But before replacing the pump I'd look more closely at the pressure control switch; for example, if the plumbing work stirred up debris in the system, crud could be blocking the pressure sensing input of the pressure control switch, causing it to misbehave. - Jen 7/20/12. 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. - BK 6/6/11, I had to put a new pressure switch on, the pump was running all the time and it burn the points up. Under a normally set pressure switch, the pump should come on at 30 PSI and shut off at 50 PSI. Check for a debris clogged pressure sensor; check for a thermal overload problem with the pump motor. On 2017-07-07 by (mod) re: sprinkler system makes the pump run continuously, Jim,My guess is that there isn't something further that you can do, because the rate at which you are drawing water exceeds the flow rate of your well or the pumping rate of your pump. thanks - Mike Jones 8/22/11. Mike, first establish that there is a leak, and in what segment of the whole system it exists - say in the building vs between the water pressure tank and the bottom of the well. If you have no air in the system the switch should work normally. 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. Also sometimes it runs constantly and will not shut off. Isn't the point of the pressure switch & bladder tank to make the pump stay on while water is running, keeping the pressure constant? Type FHG - PUMPTROL Compressor Pressure Switch give complete detail about the adjustment screws for a water pump pressure control switch.You'll see that there are estimates for about how much pressure is represented by one turn of the adjustment nuts (against spring pressure of course, so you'll need to re-tighten until the slack is gone;When the system operates observe its pressure and behavior and that will help you see what further direction you want to adjust the two adjustment nuts. Eric please search InspectApedia for WATER PUMP SHORT CYCLING to read the causes, diagnosis, and cure of this problem. If above ground, is it a one line or two line jet pump? Finally, compare the pump capacity and lift height of the water with the pump specifications. Is it the pump pressure switch or something else. When forced to on postion they bounce right back into off ppostion. During the time that the pump is on it is supposed to stay on and not cycle off until the time timed cycle is complete. Please.
