so I had a frozen shower today- the lines are cvpvc, I was able to put a space heater in the room and thawed them out with no damage-- LUCKY I know. 10*and windy
The supply lines come out of the house to the addition and t off for the sinks and toilet and continue to the shower- only the shower froze so I think it is right at the shower bay where the issue is.
Interior wall 2' off the exterior wall, slab on grade. I can't remember if I insulated the wall bay with the pipes and it is a slab on grade with a hole into the dirt for the tub trap....
I am thinking about cutting a hole in the wall and insulating the lines right there and stuffing the wall with insulation.....
Thoughts?
