What is the minimum number of times you should fill and flush the tank with water before using a cleaning solution?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 2

Filling and flushing the tank with water before using a cleaning solution is an essential practice to ensure proper cleaning and prevent contamination. Flushing the tank twice allows for thorough removal of any residual pesticides or other substances from previous uses. This helps to prevent unwanted chemical interactions and ensures the effectiveness of the cleaning solution. While flushing once may seem adequate, it does not sufficiently guarantee the removal of all contaminants, which could lead to ineffective cleaning or potential chemical reactions. Flushing three or more times may be overly cautious in many situations, especially when the goal is to effectively prepare the tank for its next use without introducing contaminants. Therefore, flushing the tank two times strikes a good balance between thoroughness and practicality.
