They just finished putting in our new natural gas lines, but we still have at least 60% of propane to use up before we get our appliances switched over. The people that put in the lines is stating that we still need someone to come out and take the outlet to the new line (that I guess they had to put in a different location), dig a pathway under out sidewalk and fit it into the side of the house that is near our existing line? I have no idea. Anyway, we need to get this done before winter and the ground freezes. Who does this type of thing? Is it a plumber? (that is what the guys that DTE hired to install the new line suggested).
