OK, As I posted in an earlier thread, I just bought a piece of land that has a well that has been sitting for about two years. I called the well people that installed to get info on what I have, like you guys said. Now, I have a 1 hp submersible pump and the well guy said it could be hooked up to 115 volts or 230. What's the difference? How do I tell which way it is hooked up? Are there any pro's or con's as to which way I hook it up?
