Signs Your Backflow Valve Needs Attention
- It's never been inspected or tested since installation
- You've had a sewer backup before, even with a valve installed
- Visible corrosion or damage at the access point
- The flap doesn't move freely when checked
- You're not sure it was installed correctly in the first place
What a Backflow Valve Actually Does
During heavy rain or fast spring melt, Winnipeg's municipal sewer system can become overwhelmed, and wastewater can push backward into homes through the lowest drain — usually a basement floor drain. A backwater valve is a mechanical flap that allows wastewater to flow out normally but closes automatically to block anything from flowing back in. It only works, though, if it's properly installed, unobstructed, and mechanically sound.
Why Inspection Matters, Not Just Installation
A backwater valve that's installed but never checked again is a real risk — corrosion, debris buildup, or a flap that's stuck open all defeat the purpose silently, until the one time it's actually needed during a storm. A proper inspection confirms the valve moves freely, seals properly, and hasn't been compromised since installation.
What an Inspection and Repair Visit Includes
Access to the valve chamber, a check that the flap operates correctly and seals fully, clearing of any debris preventing proper operation, and repair or replacement of worn components where needed. If the valve was installed incorrectly or is beyond repair, that's identified and explained clearly before any further work.
