Hard Water and Clogged Sprinkler Nozzles in St. George
Mineral buildup can distort spray patterns, reduce flow, and leave dry areas in Southern Utah landscapes. A nozzle that looks intact may still be partially blocked. Inspect screens and nozzles, compare the spray with nearby heads, and replace worn parts when cleaning no longer restores performance.
Repeated clogs can point to debris in the line, a damaged filter, or a broader pressure problem. Drip emitters also need inspection because their small openings clog more easily.
