Do you need to know how to adjust well pressure switch? The factory setting is usually 30/50, with 30 psi being the cut-on pressure. The best well pump models make it easy to switch pressure.
For many people, this pressure setting is too low. The well pressure switch is very important, as it controls the pressure in your pump and water system. You’ll want to keep reading this guide if you need to know how to adjust well pressure switch settings.

What Is a Pressure Switch in a Well?
A pressure switch is the part in your pump that tells the well pump to start or stop pumping the water. Pressure switches control the pressure level in the tanks. You’ll want to adjust the settings to meet your home's water needs if you're currently not getting enough water.
Pressure switches are made of several parts and use water pressure to run. The pressure moves a diaphragm in the system up and down, which lets the machine know when to close and open. When the pressure drops, the electrical circuit closes, allowing the pump to run.
Types Of Pressure Switch Settings
There are two types of pressure switch settings. Here is how they work:
Common Well Pressure Switch Problems
There are many different problems that can arise with a well pressure switch. These are the problems you’ll run into the most often:
Switch Won’t Turn On Or Off
Switch Clicks On And Off Repeatedly

Water Is Leaking From The Internal Mechanism
How To Adjust Well Pressure Switch Properly (Step By Step Guide)
1. Prep Your Tools
First, you’ll need to gather your tools. All you need is a good set of plumbers’ pliers. Before you do anything else- make sure to cut the power to the switch from the supply. Doing so keeps you safe and is essential.
2. Record Measurements
Next, you’ll need to measure and record the space between the thread of the top nut and the stud you’re moving. This step is required, in case you make a mistake and need to know where you started.
3. Adjust the Cut-In and Cut-Out Settings
The large nut changes the cut-in, while the small one changes the range. You should adjust the cut-in and cut-out first. Let’s start with the cut-in.
Rotate the smaller nut clockwise to raise the cut-in pressure and counter-clockwise to lower the cut-in pressure. The cut-out value moves as you change the settings, so the difference between the two is always 10 psi. This saves you some time since you won’t have to make as many changes.
4. Monitor the System
Finally, make sure that you keep an eye on your system after making the changes. You need to know that the correct changes were made. Also, you’ll only be able to see the new adjustment after the pump reaches its first cut-off.
Your psi setting should be 30/50 or 40/60. Lower pressures are best for older homes and homes without water appliances above the first floor. If you have fixtures on multiple floors, you’ll need to use the higher setting.
You can also make more adjustments if you feel the pressure is still off. Just make sure you monitor the system each time after!
People also Ask (FAQs)
Can I put a higher-pressure switch on my well pump?
You can raise the pressure to the settings your model says it can handle. Some go up to 70/50- others can even get as high as 90 psi. Most of the time, you don’t need to go above 40/60.
What do I do if my pressure switch is stuck open?
Start by gently tapping to see if the switch closes. Sometimes, debris holds it open. You can also breathe into the tube connecting the switch to the system. You’ll need to be gentle, so you don't damage it further.
Can you run a well pump without a pressure switch?
The pressure switch is required for safety reasons. Without it, the pump can easily burn itself out. You’ll want it installed for convenience as well, so you don’t have to worry about the pressure.
Overall, it’s easy to adjust your well pump pressure switch. You simply need to turn the nut in the direction you want to adjust the pressure. If it doesn’t seem right, you can always wait and try again.
