Backflow Prevention FAQs

What is backflow?

Customer: “What exactly is backflow, and why do I even need this thing?”

Mullen Tech: “Great question! Backflow is when water in your plumbing system flows in the wrong direction, which can pull contaminants like chemicals or bacteria back into the drinking water. The backflow prevention device acts like a safety gate, keeping your water supply clean and safe to drink. It’s a small but super important part of protecting your home and the community’s water system. If you are still unsure about what exactly this is and how important it can be, please give us a call whenever you can and we can explain and even come out to make sure you are taken care of.”

How often does my backflow prevention device need to be tested in West Virginia?

Customer: “How often do I need to have this thing checked out?”

Mullen Tech: “Here in West Virginia, including Kanawha and Putnam Counties, your backflow prevention device needs to be tested once a year by someone certified to do it—like me! It’s all about ensuring it is working properly and staying up to code with local regulations.

Who is responsible for installing and maintaining backflow prevention devices?
