Backflow testing in Denver

Denver Water requires backflow prevention assemblies on commercial, industrial, irrigation and fire line services, and on some homes depending on the hazard at the site. Each assembly must be tested when it is installed and every year after that by a certified backflow prevention assembly tester.

Test results are reported to Denver Water’s Cross-Connection Control office, and assemblies that fail have to be repaired or replaced and retested. Missing an annual test can lead to notices from the water provider.

The companies listed above test, repair and install backflow assemblies across the Denver area. Ask for the tester’s certification, confirm they will submit the report to Denver Water for you, and check whether they also handle fire line assemblies if your building has a sprinkler system.

Irrigation systems at commercial and multifamily properties usually have their own assembly, so check every service line on your property when you book the annual test.
