Diagnose and Remove Stopper

What happens here

Begin by observing the sink's drainage to confirm it is indeed slow. The first step in troubleshooting is to remove the existing pop-up stopper from the sink drain. This is typically done by simply pulling it upwards. Inspect the stopper for any accumulated hair, soap scum, or debris, as this can often be the primary cause of a slow drain.

Goal: Identify the slow drain issue and remove the initial obstruction (stopper).
