Water contamination poses serious health risks to businesses and communities.

“Did you know? Backflow incidents can contaminate entire water distribution systems within minutes, affecting thousands of people downstream.”

Understanding Backflow Prevention

Commercial Backflow Testing verifies that prevention devices function correctly under various pressure conditions. Backflow occurs when water flows backward through plumbing systems due to pressure changes, potentially introducing contaminants into clean water supplies.

Types of Backflow Scenarios

Backpressure Backflow happens when downstream pressure exceeds supply pressure, common in high-rise buildings and industrial facilities with pumps or boilers.

Backsiphonage occurs when supply pressure drops below atmospheric pressure, creating vacuum conditions that can draw contaminated water backward.

“Pro Tip: Annual backflow testing isn’t just good practice—it’s legally required for most commercial properties in Kenya to maintain health compliance.”
