Explanation / Answer

Turning off the aspirator results the pressure inside the filter flask to become less than that in the water aspirator causing the water to be drawn from the aspirator to the filter flask. Hence, when performing vacuum filtration to isolate a solid, the vacuum line is broken before the water aspirator is turned off. Further, a trap is combined with the water aspirator.
