I have lived in my house for 20 years. Property used to be an older homestead farm. Found a sink hole in my side yard and started digging. Found Black iron pipe goiing straight down into the ground with a elbow on the top of it going towards the house. Search Ohio Dept of Natural Resources site and found well coordinates. Well was drilled in 1960 and is 70’ Deep. How do I inspect and attach a pump to this pipe. No idea how far the pipe goes towards my house. Definitly doesn’t come into the house. the old farm house has been gone for years Prior to my home being built.
