Which of the following is a common equipment failure?

• A. High pH water used.
• B. Worn gaskets and seals.
• C. New seals.
• D. Expired labels.

Answer: (B)

Maintaining spray equipment hinges on the integrity of seals and gaskets, which keep pressure, prevent leaks, and ensure accurate delivery. Worn gaskets and seals are a common equipment failure because these parts are constantly exposed to chemical solutions, vibration, and temperature changes. Over time they lose elasticity, crack, or deteriorate, leading to leaks at connections, reduced pressure, and inconsistent application rates. Replacing worn gaskets and seals restores proper sealing, pressure, and spray performance, which is why it’s the best choice.

High pH water isn’t a hardware failure of the equipment itself; it’s a water quality condition that can affect chemical behavior or nozzle performance but doesn’t reflect a worn part. New seals would actually fix issues rather than represent a failure. Expired labels involve regulatory or safety requirements, not a mechanical failure of the equipment.
