Perfection Plumbing installs backwater valves that close automatically when sewage flows back toward a home. This helps keep basements, floor drains and lower-level fixtures from flooding during heavy rain. The page explains how the valve works, what plumbers check before choosing one, and why older Saskatoon homes often lack this protection. The company has served Saskatoon since 1996.
