Backflow FAQ
What is backflow?
Backflow occurs when water flows backward through your pipes, potentially drawing contaminated water (like lawn chemicals or sewage) back into the clean municipal water supply.
Do I have to get my backflow preventer tested every year?
Yes, Ontario municipalities require annual testing of commercial backflow prevention devices by a Red Seal plumber to ensure they are functioning correctly.
