We've inherited a property and are in process of getting the shallow well working. It's been vacant/abandoned for about 8 years. I have 3 pumps.
The first one is an old, broken Gould we found under the house. The metal of the pump housing is physically cracked; it looks like it might have frozen with water in it. I've verified the motor will run at 110 VAC. I mention this because it may be possible to change-out the pump part (it's bolted to the motor), and re-use the motor at some point.
The second is the old pump's replacement, a Grundfos Jet pump. It's logic circuits seem to be screwed-up, but that may be because I've only applied 110 VAC. The motor also runs for this one.
Finally, I bought a new 1 HP pump from Lowes. It was rated at 110 VAC.
From what I have read, it seems that the idea that pumps are either 110 or 220 is fairly "soft"; that they can be wired either way. Is this true? If not, is there any way to tell if a pump is one or the other? Originally I thought the Grundfos was a 110 pump, and wired it like that, but the logic circuits never worked, and the pump never moved much water, with almost no pressure. Now I am wondering if I should have been running 220 on it. I'd rather not experiment and blow something up.
I can get specific model numbers for all 3 of these pumps, if necessary. My main question is if the voltage is completely changeable, if you need to modify something first, or if it's "hard", one way or the other (110 vs. 220).
Thanks in advance.
