How many times do you need to flush the sprayer tank while cleaning it?

Flushing the sprayer tank three times while cleaning is important to ensure that any residual chemical or contamination is thoroughly removed. This process is critical in maintaining the integrity of the equipment and preventing cross-contamination, which could lead to ineffective application of pesticides or herbicides during future use. The three flushes help to dilute any remaining chemicals, allowing for a more effective cleaning, thus ensuring that the tank is ready for the next application without carrying over potentially harmful substances. This practice enhances safety for both the user and the environment, as it minimizes the risk of chemical exposure and environmental contamination.
