I bought my house in 1984. The house was built in 1970. The well is shared with the house next door and we both have our own in home jet pumps. I never knew exactly where the well was and it doesn't have an above ground cap. The neighbor is in a nursing home and no one lives there right now so I can't ask him if he knows. There is no problem right now except that I am in the process of replacing my 44 year old jet pump. Because of the age of the well I would like to find out where it is just in case. How can I go about doing this?
