Fire line backflow testing rules in Dallas
Any building in Dallas 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). Dallas Water Utilities 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 Dallas buildings
We schedule fire line tests in Dallas 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 Dallas 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 Dallas Water Utilities and provide a copy for your fire inspection file.
Dallas water authority: Dallas Water Utilities
Dallas Water Utilities requires annual backflow assembly testing for every property with an irrigation system, fire line, or commercial water connection. Failure to test on time can lead to fines or service interruption. Our crews cover every Dallas ZIP code and file your test directly with DWU the same day.
We submit your passing fireline backflow testing report directly to Dallas Water Utilities — no paperwork on your end. Dallas Water Utilities mails an annual notice with a firm due date and can assess penalties or interrupt service if a passing report is not on file.
