What to check for Longmont
Use this page when the assembly already failed and the next step is repair, retest, and accepted report submission.
- Due basis: Longmont requires annual testing by certified testers, says new and replacement assemblies must be tested after installation, and publishes a notice-and-enforcement sequence that starts 45 days before the due date and can escalate to civil penalties and water suspension.
- Who is affected: Longmont customers with backflow assemblies, especially non-single-family properties, irrigation services, and homes with higher-hazard conditions like fire suppression or boilers.
