What is a Backflow Preventer?

A backflow preventer is a critical device installed in your plumbing system that allows water to flow in one direction only. This prevents contaminated water from flowing back into your clean water supply due to pressure changes.



Backflow prevention is required by local regulations, and annual testing and inspections are often mandatory to ensure your system remains compliant and safe.
