Step-by-Step Repair Instructions

Follow these steps to repair the pop-up drain:

1. Turn Off Water Supply: Start by turning off the water supply valves located under the sink. 2. Remove Stopper: Lift the stopper up and unscrew the knob that secures it to the drain assembly. 3.

Test Pop-Up Mechanism: Push down on the stopper to engage the pop-up mechanism. It should open and close smoothly.

If the pop-up drain is still not working properly or there is a persistent leak, consider the following additional tips:

Check Lift Rod: Ensure that the lift rod, which connects the stopper to the pop-up assembly, is properly attached and moves freely.
Inspect Trap: Remove the P-trap under the sink and inspect it for clogs or debris that may be restricting water flow.
Lubricate Assembly: Apply a small amount of petroleum jelly or silicone grease to the moving parts of the pop-up assembly to improve its functionality.
