Protect Your Family’s Water

Residential Backflow Testing and Prevention Services

Your home’s water should always be clean, safe, and free of contaminants. Backflow occurs when dirty water flows in reverse—potentially allowing pesticides, sewage, or chemicals to enter your household water supply. At Ace Plumbing & Sewer, we specialize in certified backflow testing, prevention, and repair to keep your drinking water protected and your home compliant with local regulations. We assess your plumbing system for cross-connections, install backflow prevention devices where needed, and provide annual testing to meet municipal codes. Whether you’re dealing with irrigation systems, hose bibs, or older plumbing infrastructure, our expert technicians ensure your home’s water remains pure and worry-free.

Know the Risk

What Is Backflow—and Why Does It Matter?

Backflow is the reverse flow of potentially polluted water into your home’s potable water lines. It can occur during a sudden drop in water pressure (such as during a main break or nearby firefighting effort) or due to cross-connections between irrigation systems, hose bibs, and plumbing fixtures. Even minor exposure can lead to serious health hazards, including contamination by fertilizers, pesticides, sewage, and industrial chemicals.

Homes with lawn irrigation, sprinkler systems, pools, water features, or nearby sewer lines are particularly vulnerable to these risks. Without a properly functioning backflow prevention device, your home’s water supply may be at risk every time the pressure fluctuates. That’s why backflow prevention isn’t just recommended—it’s often required by municipal law and enforced through annual inspections and certifications.

Backflow Prevention Device Installation You Can Trust

If your home doesn’t yet have a backflow prevention device—or you’re unsure—our licensed plumbers can assess your system and install the proper unit. From reduced pressure zone (RPZ) assemblies to double-check valves, we choose the right device based on your water pressure, pipe configuration, and exposure risks.

All installations are completed by licensed professionals and comply with municipal and state regulations. We also handle permitting and schedule inspections so you don’t have to worry about the red tape.
