Fire line backflow testing rules in Grapevine
Any building in Grapevine 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). City of Grapevine Public Works – 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 Grapevine buildings
We schedule fire line tests in Grapevine 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 Grapevine 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 City of Grapevine Public Works – Utilities and provide a copy for your fire inspection file.
What fireline backflow testing looks like in Grapevine
Fire line testing is a major part of our Grapevine work: sprinklered hotels near the Gaylord and the airport entrance, conference centers, and the big-box and distribution buildings along 121 and 114. These are 4- to 10-inch double check detector and reduced pressure detector assemblies in vaults or riser rooms. We coordinate the outage with building engineering and the alarm monitoring company so the system is down for minutes, not hours.
