Backflow Prevention Assembly Testing

Backflow preventers protect the public water supply from contamination. Many water providers require annual testing by a certified tester — we test, document and help you submit results.

What this service involves

A backflow prevention assembly keeps water from your building — including stagnant water in fire sprinkler piping — from flowing backward into the public water supply. Fire sprinkler connections and many commercial water services are required to have one.

YearRound tests backflow assemblies on fire lines and domestic services, records the results, and helps you meet your water provider’s submission process. If an assembly fails, we explain why and quote the repair.

What’s included

  • Annual testing of double check, reduced pressure and detector assemblies
  • Fire line and domestic water assemblies
  • Test report completed per water provider format
  • Submission support for your water provider’s program
  • Repair and rebuild quotes for failed assemblies
  • Coordination with fire sprinkler inspections

Why it matters

  • Cross-connections can allow contaminated water to enter drinking water lines.
  • Water providers in the Greater New Orleans area operate cross-connection control programs and may require periodic testing by a certified tester — requirements vary by provider.
  • Shutting off a fire line for backflow work can impair sprinkler protection, so testing should be coordinated with sprinkler service.

Frequently asked questions

How often does a backflow preventer need to be tested?

Most water providers require at least annual testing, and some require testing after installation or repair. Requirements vary by water provider, so check the notice from your provider or ask us to confirm.

Who can test a backflow preventer in Louisiana?

Testing must be performed by a properly certified backflow tester. Requirements and accepted certifications are set by the state and your water provider.

Will testing shut off my water?

Water to the assembly is shut off briefly during the test. For fire lines, we coordinate the short impairment with your team and monitoring company.
