a friend wants me to help him with a water line going to his barn that will feed a frost free hydrant. The question is can we tee off existing water line under ground before it goes into house and pressure tank. I was told the existing line is 1 inch and is approx. 60' from house. The length to the barn is 350'. Can this be done and what material would I need. I'm well versed in the Utility laws and will make the call to Miss Utility
