understand sewer backflow risks
Sewer backflow happens when water or waste flows in the wrong direction into your property, and sewer backflow prevention in Edmonton starts with stopping that reverse flow before it reaches your home. A backflow preventer valve stops that reverse flow, protecting your basement and water supply.
A 2023 survey found that 85 percent of Canadians want action on climate adaptation (Insurance Bureau of Canada), and backflow protection is one practical step. Edmonton’s heavy spring rains and summer storms can overload sewers, pushing water back into households. In winter, ice can freeze pipes and force residual water into living spaces.

Picking a qualified team ensures your valve works when you need it. Look for certification, experience, and local knowledge.
certification and local regulations
In Alberta you need a Restricted Certificate of Competency “R” for sewer and water services. Contractors with a Private Sewage Certificate “PS” or Restricted Private Sewage Certificate “RPS” can also handle these installations (Government of Alberta). That guarantees your service meets provincial codes.
what to look for in providers
- Proper licensing and insurance

- Experience with Edmonton’s seasonal challenges
- Membership in local industry groups or professional plumbers in Edmonton directories
- References and community involvement (for example local partnerships with outreach groups)

maintain your backflow preventer valve
Regular upkeep keeps your valve ready for sudden pressure changes or blockages. A neglected valve can stick or leak, leaving you unprotected.
annual testing requirements
Local requirements and utility standards support testing your backflow preventer once a year to stay compliant (EPCOR cross-connection control). Kingstree Plumbing offers annual inspections and certified testing that meet Alberta standards.
