Backflow Test Colorado

That backflow test letter isn't junk mail.

Colorado districts must make you test your backflow assembly annually, by a certified tester — and can shut off your water when you don't. Here's what yours requires.

How it works

  1. Decode the letter

    Your district's notice comes from a state-mandated program. What it demands, whose deadline applies, and what ignoring it costs.

  2. Know your district's process

    Some districts take reports by email, some use BSI Online or SwiftComply, one outsources to Denver Water. The letter tells you which — we translate.

  3. Book a certified tester

    Testing must be done by a certified backflow assembly tester. Tell us your district and we'll connect you with one who files the paperwork right.

Why the backflow letter blindsides people

The letter reads like a scam — an obscure valve, a deadline, a shutoff threat. It's real: CDPHE's Regulation 11 requires every Colorado water system to run exactly this program.

  • Every district runs its own version: different deadlines, different forms, three different submission systems. The state literally hands each supplier a template and lets them fill in the blanks.
  • Ignore it and the water goes off — and turning it back on isn't free. Denver Water's own FAQ covers the $250 charge that lands on your bill after a backflow shutoff.
