Certified Backflow Testing, Installation & Repair for Homes & Businesses Across Eastern NC
Backflow prevention protects your water supply from contamination by keeping used, non-potable water from flowing backward into the clean water system — a requirement most municipalities across Eastern North Carolina take seriously, especially for irrigation systems, fire sprinklers, and commercial properties. C&M Plumbing & Septic provides complete backflow prevention services for residential and commercial customers throughout Mount Olive, Wayne County, and Eastern North Carolina, backed by certified technicians and over two decades of local plumbing experience.
Whether you need an annual test to stay compliant, a new device installed, or a failed device repaired, our team handles it all — start to finish.

Our Backflow Services
Backflow Testing & Certification
Most backflow devices require annual testing to remain compliant with local water regulations. Our certified technicians test and certify RPZ assemblies, double check valve assemblies, pressure vacuum breakers, and more. Learn more about our backflow testing and certification process, including fast scheduling and full documentation handled for you.
Backflow Installation
Building new, adding irrigation, or bringing a property up to code? We install backflow prevention devices for residential and commercial properties throughout Eastern NC. Visit our backflow installation page to see the devices we install and how our on-site estimate process works.
Backflow Repair & Replacement
A failed test doesn't always mean a new device. We take a repair-first approach whenever possible, and re-test every repaired device on the same visit to confirm it meets required standards. Read more about our backflow repair and replacement services and what typically causes a device to fail.
Why Backflow Prevention Matters
Backflow prevention devices exist to protect drinking water from contamination, which is why most municipalities require annual testing and proper installation on qualifying properties. Many water authorities across Eastern NC send annual notices reminding property owners to test and certify their devices, and staying ahead of that deadline is far easier than scrambling after a compliance notice arrives.
