Why it matters to you
Lawn irrigation is common across Lowcountry neighborhoods, and an irrigation line is exactly the kind of cross-connection that can pull fertilizer- or pesticide-tainted water back toward your household supply.
Practical guidance
Find out whether your irrigation system or other equipment has a testable backflow assembly and whether your water provider requires periodic testing by a certified tester. Leaking or dripping assemblies should be repaired promptly, not bypassed.
