Are You at Risk for Backflow Contamination?
Backflow hazards are common near outdoor spigots, irrigation heads, chemical feed systems, and submerged hoses. Common risk examples include:
- Sprinkler heads near fertilizers or pooled water
- Sinks with hoses submerged in mop buckets or cleaning chemicals
- Cross-connections in irrigation, HVAC, or chemical systems
Most commercial and irrigation systems are required to install and test backflow devices annually. These services must be completed by certified testers and documented for your water provider.
Work with a Certified Backflow Tester
If you’ve been notified that your property requires a backflow prevention device—or if you need help with annual testing—MCM Plumbing is here to help. Owner-operated and fully certified through AWWA, we ensure your backflow system is tested accurately and reported correctly to your local agency.

How Backflow Testing Works
Some systems are protected by air gaps, but most require a mechanical backflow preventer. To ensure continued protection, the device must be tested regularly using certified methods.
Backflow testing involves temporarily shutting off water downstream of the device and using a specialized test kit to verify that internal valves are functioning properly. If repairs are needed, we’ll provide a fast and affordable solution to get you back in compliance.
