Maintaining optimal water pressure in your home is essential for ensuring smooth operation of plumbing fixtures and appliances. The well pump pressure switch plays a crucial role in regulating water pressure by turning the pump on and off as needed. When the water pressure drops below a certain threshold, the switch activates the pump, which then pressurizes the water system. Conversely, when the pressure reaches a predetermined maximum, the switch shuts off the pump to prevent over-pressurization.
Adjusting the well pump pressure switch is a relatively simple task that can be accomplished by homeowners with basic plumbing knowledge. However, it’s important to take necessary safety precautions and follow the manufacturer’s instructions carefully to ensure proper functioning of the system. Before making any adjustments, turn off the power to the pump and release any pressure in the system by opening a faucet. Once the system is depressurized, you can proceed with adjusting the pressure switch settings.
The pressure switch typically has two adjustable settings: the cut-in pressure and the cut-out pressure. The cut-in pressure is the minimum pressure at which the pump turns on, while the cut-out pressure is the maximum pressure at which the pump turns off. The ideal pressure settings will vary depending on the specific water system and fixtures in your home. However, a common starting point is to set the cut-in pressure around 30 psi and the cut-out pressure around 50 psi. Once the adjustments are made, turn on the power to the pump and observe the system’s performance. If necessary, fine-tune the settings until the desired water pressure is achieved.
Understanding the Importance of Well Pump Pressure Switch
A well pump pressure switch is an essential component of your well water system, responsible for maintaining optimal water pressure and ensuring a consistent water flow. When properly adjusted, it prevents excessive pressure that could damage pipes and appliances and ensures sufficient pressure for household needs. Understanding the function and significance of a well pump pressure switch is crucial for the smooth operation of your water system.
Functions of a Well Pump Pressure Switch:
- Controls Water Pressure: The pressure switch monitors water pressure in the system and regulates the pump’s operation to maintain a set pressure range.
- Prevents Excess Pressure: When water pressure reaches the maximum limit, the switch trips, stopping the pump to prevent high pressure from damaging components.
- Activates Pump When Needed: As water is drawn from the system, the pressure decreases. When it falls below the lower pressure limit, the switch signals the pump to turn on and replenish the water supply.
Benefits of Properly Adjusted Pressure Switch:
- Prevents System Damage: Prevents excessive pressure that could burst pipes, damage fixtures, or strain appliances.
- Ensures Optimal Water Pressure: Provides sufficient water pressure for household activities, such as flushing toilets, showering, and running appliances.

Adjusting the Cut-On Pressure
The cut-on pressure is the pressure at which the pump starts running. It should be set slightly above the pressure required to meet the demand of the home. To adjust the cut-on pressure:
1. Turn off the power to the pump.
2. Locate the pressure switch.
The pressure switch is usually located on the side of the pump or near the pressure tank.
3. Adjust the cut-on pressure setting.
Most pressure switches have two adjustments: a cut-on pressure setting and a cut-off pressure setting. The cut-on pressure setting is typically labeled "P1" or "PS." Use a wrench to turn the cut-on pressure setting screw clockwise to increase the pressure or counterclockwise to decrease the pressure.
4. Turn the power back on to the pump.
Run the pump for a few minutes to allow the pressure to stabilize. Check the pressure gauge to make sure that the cut-on pressure is set correctly. If the pressure is still too low or too high, repeat steps 2 and 3 until the pressure is set correctly.
|| Cut-On Pressure Setting || How to Adjust ||
|—|—|—|
| Increase the cut-on pressure || Turn the cut-on pressure setting screw clockwise ||
| Decrease the cut-on pressure || Turn the cut-on pressure setting screw counterclockwise ||
Setting the Cut-Off Pressure
To set the cut-off pressure, follow these steps:
-
Identify the cut-off pressure setting. This is typically a screw or knob on the pressure switch. It may be labeled “CUT-OFF” or “HIGH PRESSURE.”
-
Determine the desired cut-off pressure. This is the maximum pressure at which the pump should turn off. It is typically between 40 and 60 psi for residential water systems.
-
Turn the cut-off pressure setting clockwise to increase the pressure or counterclockwise to decrease it. Make small adjustments at a time.
-
Turn on the pump and observe the pressure gauge. The pump should turn off when the pressure reaches the cut-off setting.

How To Adjust Well Pump Pressure Switch
Well pump pressure switches are devices that automatically turn on and off your well pump based on the water pressure in your system. When the water pressure drops below a certain level, the pressure switch turns on the pump, and when the pressure reaches a certain level, the pressure switch turns off the pump.
There are two main types of well pump pressure switches: mechanical and electronic. Mechanical pressure switches use a diaphragm to sense the water pressure, while electronic pressure switches use a sensor to sense the water pressure.
To adjust a well pump pressure switch, you will need a wrench and a screwdriver. First, turn off the power to the well pump. Then, remove the cover of the pressure switch. You will see two springs inside the pressure switch: a cut-in spring and a cut-out spring. The cut-in spring determines the pressure at which the pump will turn on, and the cut-out spring determines the pressure at which the pump will turn off.
To adjust the cut-in pressure, turn the adjusting nut on the cut-in spring clockwise to increase the pressure or counterclockwise to decrease the pressure. To adjust the cut-out pressure, turn the adjusting nut on the cut-out 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.
