Plugged nozzles are most often caused by which?

Plugged nozzles are most often caused by which?

• A. Wrong screen mesh or dirty tank.
• B. Incompatible nozzle material.
• C. Improper spray pattern.
• D. Excessive pressure in the main line.

Answer: (C)

When a nozzle is plugged, the liquid can’t flow and atomize as designed, so the spray pattern becomes abnormal. A partially blocked nozzle can’t deliver the intended distribution, yielding a weak, irregular, or constricted spray instead of the expected cone or fan. That visible change in how the spray exits the nozzle is the most direct sign of the plug, making an improper spray pattern the best clue for this issue. The other options describe upstream causes or different symptoms that don’t as directly reflect the plugged-nozzle condition.
