Backflow Prevention & Testing Phoenix AZ
Protect Your Water Supply with Certified Backflow Services
Backflow may sound technical, but it’s a serious plumbing issue with real health consequences. When water flows in the wrong direction—from contaminated sources back into your clean water supply—it can introduce bacteria, chemicals, or waste into the water you drink and use daily.
At Phoenix Plumbing Co., we provide expert backflow prevention and testing in Phoenix AZ to help keep your home or business safe, compliant, and protected. Whether you need annual testing, a new backflow preventer installed, or urgent repairs, our licensed plumbers are here to help.
What Is Backflow and Why Does It Matter?
Backflow occurs when water reverses its normal direction—often due to a sudden drop in pressure (known as back-siphonage) or a force pushing water in the wrong direction (back pressure). When this happens, dirty or hazardous water can flow into your clean water system.
This contamination can come from:
- Lawn irrigation systems
- Commercial kitchens or restaurants
- Fire suppression systems
- Pools, fountains, or water features
- Hose bibs or outdoor faucets
- Industrial equipment connected to plumbing lines
That’s why the City of Phoenix and surrounding municipalities require
backflow prevention assemblies for many properties, as well as
annual backflow testing by a certified professional.
