FAQ
Why do I need annual backflow testing? expand_more
Colorado Department of Public Health and most municipal water utilities (Denver Water, Aurora Water, Boulder PWD, City of Fort Collins Utilities) require annual testing of all reduced-pressure (RPZ) and double-check (DCVA) assemblies protecting the potable water supply. Failure to submit a test report risks water service interruption.
Are your testers state-certified? expand_more
Yes. Our backflow testers hold current State of Colorado certification and ASSE 5110 credentials. Certificate numbers are included on every test report submitted to your water utility.
What if my assembly fails the test? expand_more
We carry rebuild kits for the most common Watts, Febco, Wilkins, Apollo, and Conbraco assemblies on our trucks. Most failures are corrected and re-tested the same visit. Replacement assemblies are quoted and scheduled within 48 hours.
Do you submit the test report to my water utility? expand_more
Yes. We file directly with Denver Water, Aurora Water, Boulder PWD, Fort Collins Utilities, Greeley Water, Cheyenne BoPU, and most Front Range utilities — usually within one business day of testing.
