Here is the situation. I live in Houston, TX in a 1968 home that has been re-piped with PEX. I have a detached garage which is attached to the house via a breezeway. In the breezeway, there is a 1/2 PEX line that goes from the attic, into the breezeway, into the open ceiling of the uninsulated garage and down to the a hosebib.
The pipe is insulated with foam insulation the entire way, and is encased in 1" PVC conduit through the breezeway (And I HOPE the insulation is in there too, no way to verify)
My goal is have another Winter Storm Yuri with no worry of frozen pipes. I just want life to go on as normal. I do not know if this pipe froze in that storm.
There is no insulation in the garage, and no insulation in the breezeway. The pipe is TIGHT inside the conduit, and there is no way to add heat tape to the inside of the conduit, or even wrap it outside. I can fish other things through the breezeway, but they won't be touching this pipe.
My thinking is that if I add heat tape to the pipe in the garage, the fact its above freezing significantly in the attic, and in the garage, means it won't freeze through the 24ft run in the breezeway
What do you think?
I will always have power, so that is no concern.
