Water pressure is essential for a comfortable home, and a properly functioning well pump is key to maintaining that pressure. If your well pump is not providing enough pressure, it can be frustrating and inconvenient. Fortunately, adjusting the pressure switch is a relatively simple task that can be done by most homeowners with basic tools. In this article, we will provide step-by-step instructions on how to adjust the pressure switch for your well pump, so you can get your water flowing smoothly again.
Before you begin, it is important to gather the necessary tools and materials. You will need a screwdriver, a multimeter, and a pair of pliers. You may also need a replacement pressure switch if yours is faulty. Once you have gathered your tools and materials, you can begin the adjustment process. First, locate the pressure switch on your well pump. It is usually a small, black box with two wires connected to it. Once you have located the pressure switch, turn off the power to the pump and relieve the pressure in the system by opening a faucet. Next, use the screwdriver to loosen the locknut on the pressure switch. Once the locknut is loose, you can use the pliers to turn the adjustment screw. Turning the screw clockwise will increase the pressure, while turning it counterclockwise will decrease the pressure.
Once you have made the desired adjustment, tighten the locknut and turn the power back on to the pump. Allow the pump to run for a few minutes and then check the water pressure at a faucet. If the pressure is still not correct, repeat the adjustment process until you achieve the desired pressure. Adjusting the pressure switch for your well pump is a simple task that can be done by most homeowners with basic tools. By following the steps outlined in this article, you can ensure that your well pump is providing the correct water pressure for your home.
Understanding Pressure Switch Settings
A pressure switch is a key component of a well pump system, responsible for maintaining consistent water pressure throughout your home or property. Understanding its settings is crucial for optimizing its performance and ensuring an adequate water supply. The pressure switch typically consists of two levers or dials:
- Cut-in Pressure: This setting determines the pressure at which the pump starts to operate. Setting it too low can result in frequent pump cycling, while setting it too high can strain the pump and shorten its lifespan. The ideal cut-in pressure for most domestic applications is between 20-30 pounds per square inch (psi).
- Cut-out Pressure: This setting determines the pressure at which the pump stops operating. Setting it too low can lead to insufficient water flow, while setting it too high can put unnecessary strain on the pump and pressure tank. The recommended cut-out pressure typically ranges from 40-60 psi.
The differential between the cut-in and cut-out pressure, known as the cycle range, should be about 10-15 psi. This range allows the pump to cycle on and off smoothly, maintaining consistent water pressure without placing excessive stress on the system.
| Setting | Default |
|---|---|
| Cut-in Pressure | 20-30 psi |
| Cut-out Pressure | 40-60 psi |
| Cycle Range | 10-15 psi |
Safety Precautions Before Adjustment
1. Shut off the power to the well pump.
This is essential to prevent electrical shock and ensure your safety during the adjustment process. Locate the circuit breaker or fuse box that controls power to the pump and turn it off. Alternatively, you can unplug the pump directly from the power outlet.
2. Isolate the pump from the water source.
Close the main water valve that supplies water to the pump. This will prevent water from flowing into the pump while you are adjusting the pressure switch. Remember to open the valve again once you have completed the adjustment
3. Relieve pressure from the pump and system.
Open a faucet or valve downstream from the pump to release the water pressure. You can also open a bleeder valve on the pressure tank or the pressure switch itself if one is available. Keep the faucet or valve open until water stops flowing, indicating that the pressure has been released. Additionally, if your system has a pressure relief valve, it may automatically release excess pressure when the pump is turned off.
4. Wear appropriate protective gear.
To protect yourself from water and potential debris, wear safety glasses, gloves, and old clothes.
Adjusting the Cut-Out Pressure
The cut-out pressure determines when the well pump turns off. It’s typically set to 5 pounds per square inch (psi) above the maximum water demand of your home. For example, if your home requires 40 psi, set the cut-out pressure at 45 psi. To adjust the cut-out pressure, follow these steps:
1. Turn off the power to the pump.
2. Locate the pressure switch, which is usually a black or gray box mounted on the side of the pump.
3. Remove the cover of the pressure switch.
4. Find the cut-out pressure adjustment screw. It is typically labeled “C.O.” or “Cut-Out”.
5. Turn the adjustment screw clockwise to increase the cut-out pressure or counterclockwise to decrease it. Use a screwdriver or an Allen wrench, depending on the type of screw.
Here’s a table summarizing the steps:
| Step | Action |
|---|---|
| 1 | Turn off the power to the pump. |
| 2 | Locate the pressure switch. |
| 3 | Remove the cover of the pressure switch. |
| 4 | Find the cut-out pressure adjustment screw. |
| 5 | Adjust the cut-out pressure by turning the adjustment screw clockwise to increase or counterclockwise to decrease it. |
Safety Reset Procedure for Pressure Switch
Before working on the pressure switch, it’s crucial to ensure safety by following these steps:
- Shut off the power supply: Locate the circuit breaker or fuse box and turn off the power to the well pump.
- Close the water supply: Locate the water valve connected to the well pump and shut it off to prevent water from flowing into the system.
- Release pressure: Open a nearby faucet to release any remaining pressure in the system.
The 8-Step Adjustment Process
1.Locate the pressure switch: It’s typically mounted on the well pump or nearby.
2.Identify the adjustment screws: There should be two screws labeled “Cut-In” and “Cut-Out,” usually covered by plastic caps.
3.Prepare the adjustment tool: Use an Allen wrench or screwdriver that fits the adjustment screws.
4.Increase pressure: To increase the cut-in or cut-out pressure, turn the respective adjustment screw clockwise.
5.Decrease pressure: To decrease pressure, turn the adjustment screw counterclockwise.
6.Test the adjustment: Turn the power and water supply back on and monitor the pressure gauge to ensure it meets the desired settings.
7.Repeat steps 4-6: If necessary, repeat the adjustment process until the pressure values are within the desired range.
8.Finalize settings: Once the adjustment is complete, tighten the adjustment screws securely and replace any plastic caps.
Importance of Regular Maintenance
Regular maintenance of your well pump and pressure switch is crucial for ensuring their optimal performance and longevity. Here are some key reasons why:
1. Prevents Premature Failure: Regular maintenance can identify potential issues before they develop into major problems, preventing premature failure of your pump or pressure switch.

How To Adjust Pressure Switch For Well Pump
A pressure switch is a device that turns on and off a well pump based on the water pressure in the system. If the pressure drops below a certain level, the switch will turn on the pump. If the pressure rises above a certain level, the switch will turn off the pump.
Most pressure switches have two adjustable settings: the cut-in pressure and the cut-out pressure. The cut-in pressure is the pressure at which the pump will turn on. The cut-out pressure is the pressure at which the pump will turn off.
To adjust the pressure switch, you will need a wrench and a screwdriver. First, turn off the power to the well pump. Then, locate the pressure switch. It will usually be mounted on the wall near the well pump.
Once you have found the pressure switch, remove the cover. You will see two springs inside the switch. The spring on the left is the cut-in spring. The spring on the right is the cut-out spring.
To adjust the cut-in pressure, turn the nut on the left spring clockwise to increase the pressure or counterclockwise to decrease the pressure. To adjust the cut-out pressure, turn the nut on the right spring clockwise to increase the pressure or counterclockwise to decrease the pressure.
Once you have adjusted the pressure switch, replace the cover and turn on the power to the well pump. The pump should now turn on and off at the correct pressures.
