Backflow testing questions
How often is backflow testing required?
Most water authorities require annual testing of backflow prevention assemblies. Some higher-hazard connections require it more often. We track your specific deadline.
Do you file the paperwork with the water authority?
Yes. We complete the certified test report and submit it directly to your water authority, so nothing falls through the cracks.
What happens if my backflow assembly fails the test?
We quote the repair or rebuild, correct it, and retest, so you end the visit certified rather than out of compliance.
Do you test both fire and domestic water lines?
Yes. We test fire-protection assemblies and domestic-water assemblies, and can handle both in one visit.
Why did I get a notice from the city about backflow?
That is your annual testing reminder. Send it to us and we will schedule the test and handle the filing.
Can you handle multiple properties on one schedule?
Yes. We test and file for property managers and multi-site owners across the Treasure Coast on a single tracked schedule.
