Questions

Where do these Colorado backflow testing companies come from?

Colorado publishes no statewide list of backflow testers that we can use, so every business here is on the approved list of Eagle River Water & Sanitation District and Cherokee Metropolitan District: companies allowed to file backflow test reports in that water system. We read the list on July 30, 2026 and checked each company's phone against its Google profile.

Who is allowed to test a backflow preventer in Colorado?

A tester certified as Colorado's rules require, and usually one your water utility accepts. Your utility notice names the requirement. Ask any company for the tester's certificate number before the test.

How often does a backflow assembly need testing?

Most water utilities require testable backflow assemblies to be tested at installation and then every year. Your utility's notice gives your deadline and how the report is filed.

Never miss your annual backflow test

Most water utilities require the backflow assembly on an irrigation, fire or commercial line to be tested every year, and a missed test can mean a shutoff notice. Tell us when yours was last tested and we'll text you a month before it is due, with certified local testers ready to book.
