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
Open the irrigation page when the question is tied to sprinkler systems, reclaimed water, or landscape devices.
Annual or event-based timing
Hazard facilities, irrigation customers, and other Miami-Dade water customers that the county code or county program identifies as needing a service-connection assembly.
- Upon installation and annually thereafter
- Miami-Dade says certain customers, including irrigation users and listed hazard facilities, must install assemblies and have them tested upon installation and annually by a certified tester.
Non-compliance penalties
Miami-Dade places the obligation directly on the water customer to install or maintain the required assembly. The practical penalty is noncompliance with a county protection program tied to the service connection.
- Miami-Dade directly names irrigation as a trigger category.
- County code ties the obligation to the service connection, not just interior plumbing.
- Annual testing is required once the assembly is in place.
