So I recently found what I believe is a well in my backyard. Its a 1.5 inch piece of PVC that was capped off by the previous owner of the house. My question is how do I test to see if the well is still good. This would be a great alernative to using my city water to water the lawn. I have been reading about shallow and deep water wells. I really have no idea what to look for as far as seeing if its dry or not. There is one line coming out of the ground. That is all. Can anybody give me some guidance?
