Backflow Preventer Testing in Houston, TX
Annual testing and certification of backflow preventers on fire sprinkler and domestic water lines.
Protect the Water Supply and Stay Compliant
A backflow preventer keeps water from your sprinkler system, which can sit in the pipes for years, from flowing back into the public water supply. Because it protects drinking water, the water utility requires it to be tested every year and the results reported.
Reliable Fire Protection Houston inspects, tests and maintains backflow preventers on fire protection systems and domestic water lines for businesses across the Houston area. When a device fails, we repair it or replace it and retest it. See our backflow preventer services.
What a Backflow Test Covers
- Testing each check valve and relief valve against the required pressures
- Checking the shut-off valves and test cocks
- Recording the results on the test report
- Filing the report the water utility requires
- Repair or replacement of failed parts, and a retest
We test the common assembly types, including double check and reduced pressure assemblies, on fire lines and domestic lines.
How Backflow Testing Works
1. Scheduled with you. Testing needs a short shut-off of the line, so we plan it around your building.
2. Tested. Our technicians test each valve and record the readings.
3. Reported. We complete the test report and file the paperwork.
4. Fixed if it fails. Failed devices are repaired or replaced and retested, so you stay in compliance.

Backflow Testing in Houston
Houston-area water utilities require annual testing of backflow preventers on fire sprinkler lines and on commercial domestic lines, and they send notices when a test is due. A missed test can lead to fines or a shut-off.
Because the fire line backflow preventer is part of your sprinkler system’s water supply, we often test it on the same visit as your sprinkler inspection, so the water is only shut off once.
