Okay, so the other day, I had this whole thing with my well pump. I needed to figure out if it was a 220V or a 110V situation. Honestly, I had no clue where to even start, so I just dove in.
Figuring Out My Well Pump Voltage
First, I grabbed my multimeter. That’s pretty much my go-to tool for anything electrical. I made sure it was set to measure AC voltage, you know, so I wouldn’t blow anything up.
Next, I headed out to the well pump itself. I turned off the power at the breaker box – safety first, always! Then, I carefully removed the cover on the pump’s electrical box.

Inside, I saw a bunch of wires. I looked for any labels or markings that might give me a clue about the voltage. Sometimes, you get lucky, and it’s printed right there.
If no label,there are usually theee wires to check.
- Two hot wires.
- One ground wire.
- One hot and one neutral means 110v.
- Two hot wires mean 220v.
No such luck this time, so I got out my multimeter and carefully tested the voltage between the different wires. I made sure to keep one probe on a good ground point while I touched the other probe to each of the hot wires.
And there it was! The reading on my multimeter showed around 220V. So, mystery solved – my well pump is definitely a 220V model. I carefully put everything back together, turned the breaker back on, and everything was working fine.
It’s always a good feeling when you can figure something out yourself, even if it’s something as simple as checking the voltage on a well pump. Saved me a call to the electrician, that’s for sure!
