Frequently Asked Questions
What is a backflow and is it dangerous?
Backflow occurs when water flows in the opposite direction within your plumbing system, potentially allowing contaminants to enter your clean water supply. It’s dangerous because it can introduce harmful substances — like chemicals or bacteria — into the water you use for drinking, cooking, or cleaning.
How often do I need backflow testing?
Most municipalities require annual backflow testing to ensure your prevention device is functioning properly. Regular testing by a licensed plumber helps you stay compliant with local regulations and keeps your water supply safe.
How do I know if I need a backflow prevention device?
If you own a commercial property or have irrigation systems, fire sprinklers, or other cross-connections to your water supply, a backflow prevention device is typically required by law. Homeowners may also need one depending on their plumbing setup. A licensed plumber can inspect your system and confirm what’s required for your property.
