Cross Connection Control/Backflow Testing is a requirement as per the City of Calgary Water Utility Bylaws, and is part of the annual maintenance for the adequate performance of an irrigation system, and certain boiler systems.
  • It ensures the backflow devices are properly protecting your water supply from potential backflow and contamination of your drinking water supply. 
  • Homeowners should take backflow prevention very seriously, as it can have costly, even fatal consequences. Avoid costly fines and help protect our drinking water.
  • We conduct all of our testing in compliance with CSA Standards B64.10-11/B64.10.1-11 (Selection and installation of backflow preventers/Maintenance and field testing of backflow preventers). We are certified through the AWWA (American Water Works Association Western Canada Section), and are registered with the City of Calgary, as Cross Connection Control Specialists/Testers.
