Which of the following is a common sign of a worn nozzle?

A common sign of a worn nozzle is an inconsistent spray pattern. This occurs because wear and tear on the nozzle can cause it to lose its shape or create irregular openings, resulting in uneven distribution of the pesticide or other liquid being sprayed. A well-maintained nozzle should produce a consistent and uniform spray, which is essential for effective treatment and pest control.

When the nozzle is worn, you may notice that some areas receive too much spray while others receive too little, which can lead to ineffective pest management and potential damage to the treated surfaces. Recognizing an inconsistent spray pattern is crucial for an applicator to determine when maintenance or replacement of the nozzle is necessary to ensure optimal performance of the spraying equipment.

While excessive pressure buildup, low operational noise, and longer cleaning times can indicate other maintenance issues, they are not typically associated with a worn nozzle.
