Next-step paths
Start with the page that matches your situation
This page is the rule hub. Use it to confirm the governing utility workflow, then open the focused page that matches the actual situation on site.
Failed test
Open the failed-test page when the device already failed and you need the repair, retest, and reporting order.
Irrigation

Fire line
Open the fire-line page when the backflow assembly serves fire protection equipment or a managed commercial site.
Annual or event-based timing
Commercial, industrial, domestic, irrigation, and fire line services in Westminster where the city determines an approved backflow assembly is required.
- Upon installation and annually thereafter
- Westminster says all commercial, industrial, domestic, irrigation, and fire line services must have an approved backflow assembly installed when the city determines one is required, and each assembly must be tested at installation and annually thereafter.
Non-compliance penalties
Westminster's public rules frame the program as a city-enforced protection requirement across domestic, irrigation, and fire line services. Missing installation or annual testing leaves the service out of compliance with the city water system.
- Westminster explicitly includes domestic, irrigation, and fire line services in one public scope.
- Installation testing and annual retesting are both public requirements.
- The city program is broad enough to support multiple search intents without generic filler.

- Identify whether Westminster has required an assembly on the service.
- Complete the installation test or annual test on schedule.
