Off grid water systems that meet most household needs can be set up with relatively little expense. A DC pump, a solar panel, batteries, and a pressure tank are pretty much all you need to get cold water into a house or to a field for agricultural applications.
I knew something was wrong with my system because the pump would kick on every ten to twenty seconds while I was using the water. Normally it should be kicking on every few minutes of extended water use. In this video I do some troubleshooting to figure out the problem and fix it so that I can extend the life of my pump. You might have the same problem sometime with your system.
