Im trying to install plumbing in the basement for a bathroom I'm finishing. The water line is in the ceiling, and the place where I want to place the sink, and toilet are against the outside wall. Is it safe to run the plumbing line along an outside wall?
I was hoping this would be OK because:
a.) the basement is below ground
b.) I would run the pipe between the insulation and the drywall.
I should mention I'm in Alberta, and so there are some extreme conditions outside.
