Backwater Valve Installation in Stonewall
Licensed journeyman plumbers serving Stonewall, Manitoba — free estimates, flat-rate quotes.
Mawejje Custom Plumbing is your local Stonewall plumbing contractor for backwater valve installation. Our journeymen install backwater valves to prevent municipal sewer backup into your basement for homes, rental properties and small commercial buildings across the area. Winnipeg's combined sewer system can surcharge during heavy rainfall, sending sewage up your floor drain. A backwater valve seals the line when flow reverses. We install Mainline Fullport and Mission valves, cut the floor at the correct elevation, install a clear-lid access pit for inspection, and supply the documentation required for the City of Winnipeg Basement Flood Protection Subsidy. Typical dispatch in Stonewall: 45-60 minutes from base.
