Backflow Preventer Installation & Testing in Houston

A backflow preventer is a valve assembly that keeps contaminated water from flowing backward into the drinking water supply — for example, when a pressure drop could pull water from an irrigation system, boiler or commercial equipment back into the line. Call (844) 212 9767 to reach a local plumber for backflow preventer installation or testing.

Who Needs a Backflow Preventer?

• Homes with lawn irrigation (sprinkler) systems
• Commercial buildings, restaurants and medical facilities
• Properties with fire sprinkler systems, boilers or chemical-feed equipment
• Pools and other connections where water could be contaminated

Types of Assemblies

• Double check valve (DCVA) — common for lower-hazard and fire line applications.
• Reduced pressure zone (RPZ) — for higher-hazard connections; required in many commercial settings.
• Pressure vacuum breaker (PVB) — common on residential irrigation systems.

Backflow Testing in Houston

Testable assemblies must be tested when installed and typically once a year after that, with the results submitted to the water utility. In Texas, testing has to be done by a licensed Backflow Prevention Assembly Tester. A failed test usually means cleaning or replacing check valves, springs or seals.

How do I know which assembly I need?

It depends on the hazard level of the connection and local requirements; your water utility can tell you what’s required.
