About This Product

This pressure switch signals the pump to start when the water system drops to 30 psi (factory set) and stops at 50 psi (factory set). This switch is to be used with submersible well or jet pumps. It can be wired 115-Volt or 230-Volt. This switch must be used in conjunction with a well pressure tank. The air pressure in the well tank, when empty of all water, must be set to 28 psi, or the switch will not operate properly. This switch is equipped with a low-level cut-off arm that automatically shuts off a well pump when there is a dramatic decrease in pressure, such as a leak in the discharge pipes or a faulty pressure tank.

Highlights

  • Turns pump on at 30 psi, off at 50 psi
  • Cap removes for easy adjustment
  • Can be wired 115-Volt or 230-Volt
  • For use with submersible well or jet pumps
  • Motor wires are connected to the 2 middle posts (color does not matter)
  • Breaker box wires are connected to 2 outside posts (color does not matter)
  • 2-spring design allows for adjustment of cut-in and cut-out pressure settings
  • Adjustments to springs should only be made by users with good knowledge of well systems
  • Switch shuts off pump automatically when there is a dramatic decrease in pressure

    Q:Can this switch be adjusted to 20/30 so that the pump turns off at 30psi then turns on at 20psi? This is for a tiny home running on solar power with a 1/4 horsepower 120V water pump.

    Answer This Question

    A:  Yes, this would work. However, we would recommend purchasing our 20/40 pressure switch (item # PS2040). That way, you would only need to adjust the small screw (the range differential), instead of adjusting both the small screw and the big screw (the on/off pressure). To adjust the small screw differential down 10 PSI, you will turn the screw just under 3 revolutions (each turn is approximately 3.5 PSI). Also, ensure that your 1/4 HP pump can reach 30 PSI, or else the switch will never shut the pump off. Finally, if setting it to 20/30, ensure the air pressure in your pressure tank (drained of all water first) is set to 18 PSI (pressure tanks always need to be 2 PSI below the cut-in pressure of the switch).

      Q:Switches large and small. Whitch one is what?
      by|Sep 7, 2021

      Answer This Question

      A:  I think you mean spring large and small. The large spring changes the cut in and cut out pressure together. The small spring changes the cut out only.

        A great fire starter
        Purchase this to replace my old 30/50 pressure switch on my well. I am an Electrician, I did not like how much arcing the contacts were making after my initial install. Sure enough, 2 days later water cut of to the house. Went down to do a manual reset and heard an unsettling amount of arcing & started seeing smoke, i removed the cover and saw the contacts blaze red, they welded themselves to the terminals before catching fire. I killed power & returned it. Bought a Square D one instead.

          Instructions are straightforward. Make sure your pressure tank air pressure is set properly. Use a water pressure gauge to ensure water pump set points are correct. This unit was calibrated properly, no adjustments necessary. Great unit with on-off switch included.

          This item is fairly priced. Easy to install, don't forget to clean out the feed pipe to the pressure switch. Instructions are easy and spot on. You'll get years of service.

          I removed the standard pressure switches and replaced them with these with the low pressure cutoff. My well is shallow therefore susceptible to low water level. If the pump is not pumping water the pressure will drop below the cutoff thereby protecting the pump.

          This pressure switch does exactly what it says. But I have found that it doesn’t last as long as I thought or would like it to. Which has caused me to buy many of these in the past.

          It worked perfectly and was easy to put together and seems like it is very well constructed
