If you’ve ever wondered how to reset the pressure switch on a well pump, you’re not alone. Many people struggle to find this important component on their pump. This article will give you some tips on how to reset the pressure switch and find the settings on your well pump to make it run smoothly. 

Read on to learn how to reset your pressure switch on your well pump. If you haven’t done so in the past, you may want to consider calling a professional for help.

Adjusting the cut-in and cut-off pressure of your pressure switch.

In order to adjust the cut-in and shut-off pressure of your well pump’s pressurized tank, turn off the power and remove the nut covering the pressure switch. 

Turn the nut clockwise to increase pressure and counterclockwise to decrease pressure. The cut-off pressure should be set at a pressure that is two psi lower than the cut-in pressure.

Before starting, make sure you have the correct pressures. Normally, the cut-in and cut-off pressure are thirty and forty psi, but it’s possible to adjust them to anything up to forty psi. 

However, it’s critical to adjust the cut-off pressure to a lower amount because higher pressures can cause leaks in fixtures and smaller tubing. Another issue may be that the well pump is not powerful enough to reach the cut-off pressure. It may also take too long.

To adjust the cut-in and cut-off pressure, you should first check the nut sizes. There are two types of nut on pressure switches: the 1/2 nut controls the cut-in pressure, while the 7/16 nut adjusts the cut-out pressure. If you don’t have this nut, you can get a pressure switch webinar that will teach you more about them and how to use them correctly.

Locating the pressure switch

One of the first things you need to know about a well pump is where to locate its pressure switch. Pressure switches are attached to the bottom of the pressure tank and are on the top of the copper “T” fitting that connects the pump’s incoming water supply and outside water supply. 

You can visually inspect the switch by unscrewing the brass fitting and looking for corrosion or burned wire. If the pressure switch is leaking water, you should check the internal mechanism and replace it as needed.

Most well pumps have a pressure switch located inside or on the exterior. The switch is usually set on a pipe that enters the pump’s pressure tank. A jet pump, on the other hand, has the switch located on the side.

Locating the pressure switch on a well pump is easy. There are three steps you can follow:

  • Firstly, turn off power to the pump by turning off the main service panel. 
  • After doing so, use a manual screwdriver to remove the housing. 
  • Next, remove the pressure switch mechanism by lifting it off. 

Once you’ve removed the housing, you can test the switch for power by using a non-contact voltage tester. It’s possible to confuse the wires, so it’s a good idea to check the wiring documentation and ask a professional plumber for help.

Resetting the pressure switch

If you are experiencing a drop in water pressure, you can reset the pressure switch on your well pump by turning on a faucet that is located close to the pump. If the switch is faulty, you will need to reset it to get water flowing again. 

If the switch is bad, you will need to check the metal discs inside the pump. Look for any pitted or burnt surfaces. If you find one, simply pull the wires apart and reconnect them.

If the switch is bad, it may be time for a replacement. It is usually located near the front of the compartment and features a nut that is used to adjust the pressure. You may also find the manufacturer’s instructions inside the switch’s compartment. 

Regardless of its location, you’ll want to remove the switch’s cover before resetting the pressure. A new pressure switch will cost approximately $25.

A pressure switch has two settings: cut-in and cut-out. Cut-in pressure is higher than cut-out pressure. It’s cut-in and cut-out settings are based on these points. The cut-in and cut-out points are different for each type, but the settings on most pressure switches are adjustable. 

The cut-in and cut-out point should be set so that the pump’s shut-off is triggered when the pressure reaches the cut-out level, which is usually between 50 and 60 PSI.
