Fire line backflow testing rules in Addison
Any building in Addison with a fire sprinkler system has a dedicated fire line backflow assembly — usually a double check detector assembly (DCDA) or a reduced pressure detector assembly (RPDA). Town of Addison Public Works requires these to be tested annually by a licensed tester, and the fire marshal may ask for the current report during an inspection. Because fire lines are large diameter and often installed in a pit or vault, testing takes coordination — that is what our crews do every week.
Minimal downtime for Addison buildings
We schedule fire line tests in Addison around your operating hours, including early mornings, so tenants and customers are not disrupted. Our technicians notify your monitoring company before the water is isolated so no false alarm is dispatched, complete the test, then verify the system is back in service before leaving. We handle confined-space vaults, flush-mounted pits, and riser room installations.
Repairs, rebuilds, and replacements
If a fire line assembly in Addison fails, we quote the repair on the spot. We rebuild checks and relief valves, replace worn rubber and seats, and can replace the full assembly when repair is not cost effective. After any repair we re-test and file the passing report with Town of Addison Public Works and provide a copy for your fire inspection file.
