Cross Connection Control
Water distribution systems are large networks of storage tanks, valves, pumps, and pipes that transport finished water to consumers. By their design, distribution systems and infrastructure can be contaminated. Contamination most commonly occurs at a cross-connection. This is any actual or potential connection between public water and a contaminated source.
Tips for Correcting Cross-Connections
Do not submerge hoses or place hoses where they could become submerged, such as sinks, tubs, or pools
Install hose bib vacuum breakers on hose spigots
Have your plumbing system surveyed for cross-connections by a certified backflow preventer inspector
Ensure the correct backflow preventer is installed on your irrigation system
Have your backflow prevention assembly(s) inspected annually by a certified backflow preventer inspector
