Cross connection testing is the process of checking whether irrigation water could mix with drinking water through a hidden connection, such as a valve, hose, or pipe that allows water to move the wrong way. In a landscape or sprinkler system, this testing helps confirm that your setup is properly protected and not creating a contamination risk.

Why it matters

When irrigation systems are connected to a potable water supply, pressure changes can sometimes draw non-drinkable water back into the main line. Cross connection testing helps identify those risks before they become a health or compliance issue.
