Backflow Testing & Repair in Houston

Certified testing and repair for backflow prevention assemblies.

Texas requires annual testing of backflow prevention assemblies on irrigation systems connected to a public water supply. We test, complete the paperwork, submit it to your water authority, and repair or rebuild assemblies that fail.

  • Water weeping from the relief port
  • Assembly froze during a hard winter
  • You just bought the home and have no test record

How we handle it

  1. 1 Certified test with calibrated gauge
  2. 2 Rebuild check valves and relief valves if the test fails
  3. 3 Retest and document the result
  4. 4 File the report with your local water authority
