Professional testing of commercial backflow prevention assemblies.
Accurate pressure testing to verify proper assembly performance.
Thorough testing of double check assemblies for reliable protection.
Documented testing to help commercial properties maintain required compliance.
Certified testers connect calibrated differential pressure gauges to test cocks, checking relief valve opening pressure and check-valve tightness.
If an assembly fails due to worn rubbers, pitted seats, or fouled check springs, our service trucks carry OEM repair kits (Watts, Febco, Wilkins, Ames) for same-day rebuilds.
Re-testing the assembly after replacing internal check components to ensure full compliance with TCEQ performance thresholds.
Uploading official test reports directly to city portals (such as BSI Online, SCADA, or local municipal utilities) to satisfy code enforcement deadlines and prevent municipal water shutoff notices.
Supremacy offers 24/7 emergency commercial plumbing dispatch across DFW, arriving on-site within hours to contain main line backups, major gas leaks, backflow failures, or commercial water heater breakdowns.
Cities across DFW issue compliance violation notices and can terminate municipal water service if backflow assemblies are not certified annually. Supremacy provides emergency same-day testing and immediate report filing to stop pending municipal shutoff orders.
Testing requires isolating the backflow assembly for 10 to 20 minutes. For 24/7 facilities, medical centers, or restaurants, we install parallel dual-assembly bypass systems or perform testing after operational hours to ensure uninterrupted water delivery.
Yes, our technicians are licensed BPAT testers and licensed commercial plumbers authorized to perform both testing and complete mechanical repairs or full assembly replacements on the spot.
Backflow testing certifications are valid for 12 months from the date of a passing test. We maintain digital records of your facility’s test history and automatically dispatch reminders 30 days before your next annual deadline.
Our Commercial plumbers manage a comprehensive range of critical repairs, whether you're upgrading outdated piping, installing smart leak-detection systems, or designing an entirely new plumbing layout.
