Bought an old house 880 square feet on property 100 x 330. Well is at northeast end of property, approximately 250 or more feet from the house. How do I discover where the pipe is running across the yard to the house.

What material is the line to the house made of? PVC or galvanized?
Let me know, Tom

Perhaps you could try using a metal detector if you knew what the pipe was composed of, or if it isn't metal then perhaps sonar would be the answer. Hope this helped.
