Backwater Valve Installation in Winnipeg

Serving Winnipeg and every corner of Manitoba — free written estimates.

Mawejje Custom Plumbing is a licensed, insured Winnipeg plumbing contractor. We install backwater valves to prevent municipal sewer backup into your basement for homeowners, landlords and small commercial properties, with flat-rate quotes and same-day appointments wherever possible. 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.
