Question: Is double flushing or holding down the toilet handle recommended?

Answer:

Blake states that if you need to hold down the handle to flush properly, there is likely an issue inside the tank. Double flushing wastes water and suggests a performance problem. In both cases, it indicates something may need repair.

Summary:

Double flushing wastes water and holding down the handle signals internal tank issues. If either is necessary, the toilet likely needs servicing. Addressing the root cause prevents water waste and restores proper function.
