We purchased an old house that has a 3 car garage on it with a small apartment at the end of the garage. The apartment originally had water and steam heat from the house. Most of that is gone so we're starting from scratch. There is a separate water heater in the apartment so we thought we would run a single cold supply from the house.
The problem is that burying a line from the house is not practical..pavement, lot line, etc. I'm in central Indiana. I want to run a 3/4 Pex through the garage but don't know how to keep it from freezing in the worst of the winter. Is a heat tape practical and reliable over this distance (about 30 feet) or are there other options? The garage is likely to go below freezing but not by a lot.
Thanks for any help or ideas.
