What does a pressure drop on sprayers typically indicate?

A pressure drop on sprayers typically indicates that the pump is worn. When a pump wears down, it often struggles to maintain optimal pressure levels, which directly affects the sprayer's performance. As the components inside the pump age, they may not be able to generate the necessary force to push the fluid through the system at the required pressure.

While other issues such as a clogged nozzle, an empty tank, or damaged hoses can also result in reduced pressure, these conditions usually cause specific symptoms in the system that can be diagnosed differently. For example, a clogged nozzle may result in uneven or reduced flow from a specific point rather than a general drop in system pressure. An empty tank would prevent the system from operating at all, and a damaged hose might lead to leaks, further indicating issues rather than a steady pressure drop. Thus, a worn pump is the most reliable cause for a noticeable and consistent drop in pressure across the spray system.
