Protecting Northwood Hills Drinking Water From Cross Connections

Backflow occurs when non-potable water reverses direction and enters the clean supply through a cross connection. Common examples include irrigation systems, hose bibs, boilers, soda carbonators, and dental or medical equipment that connect to potable water lines. These links can allow contaminants or bacteria to enter the system when pressure conditions change.

There are two main causes of backflow. Backpressure happens when downstream pressure exceeds the supply pressure, forcing water backward. Backsiphonage occurs when supply pressure drops, creating a vacuum that pulls contaminated water into the potable system.

Both pose serious health and liability risks if backflow prevention assemblies are absent, damaged, or untested. That’s why SAWS and the Texas Commission on Environmental Quality (TCEQ) require annual backflow testing, documentation, and certification by licensed testers.

Testing protects families, employees, and the wider Northwood Hills community by maintaining clean, reliable drinking water and preventing costly violations. Anchor Plumbing Services ensures every test follows proper procedure, with results filed on time and stored for your compliance records.
