Backflow Testing
Protecting your drinking water is one of the most important responsibilities of any property owner in Minnesota, and that’s exactly what backflow testing is designed to do.
Onyx Plumbing & Gas provides professional backflow testing services to ensure your property remains safe, compliant, and protected year-round. Our certified technicians inspect, test, and document your backflow prevention assemblies with accuracy and care, so you can have peace of mind knowing your water supply is secure.
Backflow testing isn’t just a best practice. It’s required by the State of Minnesota: Review the state’s backflow rules and regulations here.
When backflow occurs, contaminated water can flow backward into your clean water supply, putting your health, building, and plumbing system at risk. Backflow prevention devices act as a critical safeguard between your plumbing and the public water system.
Over time, backflow prevention devices can wear down, fail, or become blocked. Regular testing is the only way to ensure they continue to do their job.
