Repairing our equipment strengthens our bond with it. We can avoid calling for professional help by doing relatively simple tasks such as wiring a well pressure switch during installation, troubleshooting, or repair. But how to wire a 220 well pressure switch?
You need to get a grip of the wiring diagram inside the switch box and some steps for wiring.
However, you should be aware enough throughout the process because pumps operate on dangerously high voltage.
Make sure you understand each step and the whole process. Otherwise, call for a professional and observe him adjust the wire set. In that case, this writeup will help you interpret the procedure
How To Wire A 220 Well Pressure Switch
A 220v well pressure switch contains two rooms on the breaker panel. So, locate the breaker circuit of your well and shut it off.
Next, verify which type of wire system your pump has. To start, you need a few starting tools like a screwdriver, wire strippers, fork connectors, crimps, etc. They will accelerate this process so you can even start without them and use the tools you have close by.
There are two types of pressure switches, and here is how to find them out:
- Two-Wire Pump Pressure Switch- If the wire duct from your motor doesn’t branch and goes straight to the pressure switch, then it’s a two-wire.
- Three-Wire Pump Pressure Switch- If the wire duct from your motor goes through a control box before the pressure switch, then it’s three-wire.
Steps for Two-wire Pressure Switch Wiring
If you have a two-wire system, then follow this step-by-step well pump wiring guide. Read each step carefully, then do as instructed.
Steps for Three-Wire Well Pressure Switch Wiring
If you have a two-wire system, then follow this step-by-step guide. Read each step carefully, then do as the tutorial below:

Frequently Asked Questions (FAQs)
How do you wire a deep well pressure switch?
The deep well pressure switch must be connected as per the wiring diagram for the well pump pressure switch. There generally is a wiring instruction paper inside the switch box cover. Follow our easy guide to wire your pressure switch safely or if you don’t have the instruction paper.
Where do the wires go on a pressure switch?
The wire from the breaker box goes to “1 and 4” terminals or L1 or L2 terminals. And the wire from the motor goes to Load- “2 and 3” terminals for 2-wire system R and Y. And B for the 3-wire system. Be sure about the wiring and electrical connections of the wire before installing.
Can you wire a pressure switch wrong?
There will be no problem if you mix up the two-wire ports for power supply wires (coming from breaker panel) among themselves or motor connection wires. But be sure the hot wire or power supply wire is connected to “1 and 4” terminals and motors on “3 and 4 terminals” according to our guide.
