Backflow Services Plumbing for Greater Houston
Backflow preventers protect the public drinking water supply by stopping water from reversing direction — for example, from an irrigation system, boiler, or commercial process — back into the clean supply. Most Houston-area municipalities require certified annual testing of these assemblies on irrigation connections, commercial properties, and many residential setups, and they can shut off service if testing lapses. The plumbers in our network are certified to test, repair, and replace backflow devices, file the paperwork with your water authority, and keep you compliant.

Common Backflow Services Problems in Houston

Is annual backflow testing required in Houston?
Most Houston-area municipalities require certified annual testing of backflow assemblies on irrigation, commercial, and many residential connections, and can suspend service if it lapses.
