Backflow preventers are essential for protecting the public water supply from contamination.

These devices ensure water flows in only one direction — toward your property — and stop potentially harmful substances like fertilizers, bacteria, and chemicals from flowing back into the clean water line.

They work by preventing two types of risk:

1. Back-siphonage: When low pressure in the system pulls contaminated water back into the supply
2. ‍Back-pressure: When pressure from a system (like irrigation or fire sprinklers) pushes contaminated water backward into the potable line
   

Backflow preventers are required on irrigation systems, fire sprinkler systems, and in many commercial plumbing setups. There are several types — like double check valves, pressure vacuum breakers, and reduced pressure zone assemblies — each designed for different levels of hazard.

Although annual testing and certification must be handled by a state-certified backflow tester, we specialize in the installation, repair, and replacement of all types of backflow preventers. If your device fails inspection or you suspect it’s not working correctly, we can repair or replace it quickly to keep your system safe and compliant. We also coordinate with your tester and ensure any necessary repairs are documented and reported to your local Public Works Department.

Let us take care of your backflow device — so your water stays clean and your system stays up to code.
