Frequently asked questions
How often is backflow testing required in Granville?
In Granville, most backflow prevention devices, especially those on irrigation systems and commercial properties, require annual testing and certification by a licensed professional.
What is the difference between a backflow preventer and a check valve?

If your backflow preventer fails its test, it must be repaired or replaced by a licensed plumber to ensure compliance with Granville regulations and prevent potential water contamination.
