Backflow Prevention & Testing
Ensuring Clean, Safe, and Compliant Water Systems Year-Round
Protecting your water. Protecting your business.
Clean water matters. DDC Mechanical’s certified experts provide backflow prevention, testing, and repairs across Metro Vancouver — keeping your systems safe, efficient, and compliant.
Backflow Prevention Made Simple
Backflow happens when water flows the wrong way, allowing contaminants to enter the clean water supply.
Stay Compliant and Protected with Certified Backflow Testing.
BC regulations require most commercial, industrial, and multi-residential properties to install and annually test backflow prevention devices.
If ignored, backflow can pose serious health and liability risks — but our certified testers make sure that never happens.
We’ll assess your system, install the right device, and keep you fully compliant and protected.

3. Immediate Reporting
If your assembly passes, we submit the test results directly to your City’s authorized reporting system , usually the same day.
