I believe this would give us adequate water pressure at all times. on a typical Square-D pumptol - one is the cutout, the other is the differential. If there's not a differential adjustment, the differential is not adjustable. Short nut is as low as it can go, No spring tension at all and still can't get back to 40 psi. - Pumptrol Pressure Switch Installation & Wiring Instructions (2010), retrieved 1 April 2015, Schneider Electric USA On a Square-D Pumptrol™ 9013FSF-2 pump pressure switch, for example, Square D tells us that we.

It cycles on a little less than 50 psi so still have a short cycle and a 10 psi operating range. e-mail: [email protected] Especially if the well pump is a submersible (hidden and silent down inside the actual well) you may not realize that the pump motor is not shutting off. Reader asked: We have a well and have been experiencing intermittent low water pressure. Also make sure your pressure tank has a relief valve installed. Over time, the wires can break or loosen, harming the switch's functionality. Turning the nut in a counter clockwise direction will lower that overall cut off pressure. When he turned the adjusting nut the water pump behavior and water pressure did not change. If your pump is staying on for less than 30 seconds (I prefer longer), you may be heading for trouble. After drained it reads 55 psi when I originally charged it to 38 psi. It reveals the parts of the circuit as simplified shapes, and also the power and also signal connections in between the gadgets. Shown below are the instructions for a Type 9013-series Square D Pumptrol. I would try going back to the original settings given in a table above on this page. Finally, I suspect that after you have increased the pump cut-in or cut-on pressure to a higher number, say 30 psi, if you will find that this does not fix your water pressure problem. You could try first replacing the entire pressure control switch AND making sure that there is no clog in the tube or pipe that communicates water pressure to the switch. Grainger's got your back. square d pumptrol pressure switch wiring diagram – What’s Wiring Diagram? assumed by Square D [ nor by InspectApedia.com ] for any consequences Cuts on at 20 and off at 80. Look for any wiring problems. 4) When I drain water from the tank after everything shut off, the water pressure gauge just drops to zero with no flow. Apparently, there is no way to adjust only the cut in pressure? The 1-888-SquareD But messing with the gap also shifts the operating pressure of the control so you may have to re-visit the range - or leave this nut alone. (1-888-778-2733) Put another way, many homes that operate between 30 and 50 psi have very good water pressure and flow rate at the fixtures. Adjust a Square D well pressure switch by turning it clockwise to raise the pressure and counter-clockwise to decrease the pressure. The differential adjustment nut has the practical effect of raising or lowering the cut OFF pressure only. Understanding how pump pressure control switches work and which way to turn which of the two nuts in the control can be confusing. Thanks to reader Don Travis for discussing water pump adjustment details - July 2010, Our recommended books about building & mechanical systems design, inspection, problem diagnosis, and repair, and about indoor environment and IAQ testing, diagnosis, and cleanup are at the. Watch out: Electrical equipment House of Pumps carries the entire line of Square D pressure switches. The switch label instructions say: The smaller nut (red arrow) atop the smaller spring in the pump pressure switch: changes the differential between cut-in and cut-out pressure. Pressurized the tank when empty to 38 psi. arising out of the use of I've been struggling with my Pumptrol (Square D 9013FSQ 2) pressure switch for hours, and fails to solve my pressure issue. A competent onsite inspection by an expert usually finds additional clues that help accurately diagnose a water pressure or pump problem. Yeah. Square "D" Pressure Switch with Lever, Unloader and 4 Port Manifold, Factory PSI Setting 95-125, Differential PSI 30 (Smaller HP) Square "D" Pressure Switch with Lever, Unloader and 4 Port Manifold, Factory PSI Setting 110-150, Differential PSI 40 (Smaller HP) Some pump pressure control switches such as Schneider Electric's Square D Pumptrol™ Types FTG and FHG have only a range adjustment nut. Any thoughts? First checked air pressure in an empty tank. Remember to adjust the larger RANGE nut first, then adjust the smaller DIFFERNTIAL nut. Over time, a Square D pressure switch can become worn out. This particular switch was the Square-D Pumptrol 9013FSG ( for which a contact replacement kit is available: Catalog No. Price $48.31. Where did the extra pressure/air come from? Switching point on falling pressure Grainger's got your back. maintenance personnel. Thanks for your help. Square D Pumptrol Pressure Switch is intended to monitor and control electrically driven jet pumps, submersible pumps or reciprocating pumps. At this time, the nut on the small spring backed all the way off. Turn the differential nut counterclockwise to lower cut-off pressure or turn the nut clockwise to raise cut-off pressure. That means that whatever the gap is between the cut-on pressure and the cut-off pressure, that gap is maintained, but the entire operating This category contains pressure switches manufactured by Square D. This product does not comply with the Safe Drinking Water Act, which requires that products used in any system providing water for human consumption (drinking or cooking) to meet low-lead standards. I’m afraid to tamper with it too much seeing how we went 3 days with no water at all already but the air is getting worse and I find it looses pressure and kicks in more often when no water is even running.

You may be best to leave this adjustment screw alone. In modern pressure control switches both nuts are typically sized to be turned with a 3/8" nut driver or socket. Simply adjust the correct screw to adjust the differential. Square D Pumptrol pressure switches are commonly found in many commercial and residential plumbing applications that require the regulation of water pressure. Or use the SEARCH BOX found below to Ask a Question or Search InspectApedia. Chopping off the cutout screw spring won't help a bit. In sum, the "Range" nut shifts the whole operating range of the pressure control up or down, but keeps the gap between cut-in and cut-out the same. Turning the smaller nut and spring will adjust the upper end cut off pressure. The cut-off is OK but the cut-on needs to be 40 or 50. A water pump pressure switch tends to operate at a lower pressure, while an air compressor operates at a higher pressure. 8001 Knightdale Blvd. But I don't see how that is going to put more water in the tank.
