Is it advisable to operate a pump dry for a few minutes to drain any liquid from the sprayer system?

Operating a pump dry is inadvisable because it can cause significant damage to the pump. When a pump runs without liquid, it can result in overheating, increased wear, and the potential for failure due to lack of lubrication and cooling that the fluid provides. Most pumps, regardless of their type, are designed to be used with liquid in the system for optimal performance and longevity.

While draining the sprayer system is a necessary task to avoid contamination or damage from residual pesticides, it should always be done in a manner that ensures the pump is not running dry. Instead, proper procedures should be followed to drain the system without causing harm to any equipment involved. This method of operation not only preserves the pump's integrity but also maintains safe practices in pesticide management.
