Is your deal on city water or on well water? It makes a big difference....
I have always been hooked up to city water and city sewer. You hardly ever think about your water supply. If you depend on a well or a septic system, things are way different.
Hopefully the 10 minute video I found below will help somebody learn the basics about wells.
If you are working on a deal, any deal, one of your major considerations should be whether the property has city water and city sewer or a well and septic system.
