How to Keep Pipes from Freezing in an Unheated Garage
Key Takeaways Protect garage pipes by sealing drafts first, then insulating the pipe and adding approved heat cable where exposure warrants it. Foam sleeves slow heat loss but do not create heat, so insulation alone may not protect a pipe through a prolonged freeze. If a garage utility sink will not be used, shut off its dedicated supply and drain the line where the plumbing setup allows. Use only heat tape or cable approved for the pipe material, follow its instructions, and never overlap it unless the manufacturer explicitly permits that.
