Avoid plumbing on exterior walls in cold climates

Description

In climate zones 5+, run plumbing through interior walls (not exterior) to avoid freeze risk. If unavoidable, use wider studs (2×6+) with insulation behind the pipe.

Why this exists

Exterior wall freeze-burst is a top winter claim type.
