Frequently asked questions
How often is backflow testing required in Portsmouth?
In Portsmouth, 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?
A backflow preventer is a more robust device designed to prevent contaminated water from re-entering the potable water system, while a check valve primarily prevents water from flowing in the opposite direction in a pipe.
What happens if my backflow preventer fails its annual test?
If your backflow preventer fails its test, it must be repaired or replaced by a licensed plumber to ensure compliance with Portsmouth regulations and prevent potential water contamination.
