What Is Backflow Testing and Why It’s Important

Backflow happens when water flows in the wrong direction through your plumbing system. This can cause contamination of drinking water with chemicals or waste.

Annual backflow testing confirms that your backflow prevention device is working properly and meets Texas Commission on Environmental Quality (TCEQ) standards.

Regular inspections protect public health and help you stay in code compliance.
