Yes — Colorado state regulations require annual testing and certification for most commercial properties and many residential irrigation systems connected to the public water supply.
What happens if I fail my backflow test?

We test all assembly types including Reduced Pressure Zone (RPZ), Double Check Valve (DCV), Pressure Vacuum Breaker (PVB), and Atmospheric Vacuum Breaker (AVB) assemblies.
