Reasons to arrange an assessment
- The home has experienced a sanitary or storm sewer backup.
- The municipality recommends private-side protection.
- Neighbouring properties have reported surcharge flooding.
- The basement is being renovated and the drain layout is accessible.
- You are unsure whether an existing valve is present or serviceable.
Reasons a valve may not be suitable
Shared laterals, multiple dwelling units, unusual drainage connections, inaccessible pipe, poor pipe condition or code restrictions may require another approach.
Questions
Can I install or service the valve myself?
Backwater-valve installation is regulated plumbing work and should be performed through the appropriate qualified and licensed contractor. Homeowner maintenance should follow the manufacturer instructions and local safety guidance.
How often should the valve be checked?
Follow the manufacturer instructions and local guidance. Some authorities recommend inspection every three months, while other programs recommend at least annual or pre-storm checks.
What if I cannot find the access?
Do not assume the valve is maintenance-free. A plumber or drainage contractor can help locate the device and determine whether the access has been covered or removed.
