A broken drain plug could be the culprit when your bathroom sink fails to hold water or seems to take forever to drain. A worn gasket beneath the plug or a broken tail piece can cause the pop-up drain plug to stop working. A build-up of hair and soap scum around the tail piece can also cause the water to drain slowly from the sink. Removing the old pop-up drain plug and replacing it when a new one will help your bathroom sink hold water when you need it, and drain quickly when you don’t.
Remove anything stored beneath the bathroom sink to access the pop-up drain plug assembly. Look behind the sink drain beneath the sink for the clevis. It resembles a flat metal rod with several holes punched in it. The pivot rod extends horizontally from the sink drain and connects to the clevis with a spring clip. A retaining nut holds the pivot rod in the sink drain. The pop-up lever, also known as a stopper-rod, connects to the top of the clevis with the clevis screw.
Unscrew the pivot rod’s retaining nut holding the rod in the sink drain. Use pliers to loosen it if the nut is too tight to be loosened with your fingers.
Pull the pivot rod from the sink drain. The pivot rod threads through a small plastic or metal pivot ball and into the pop-up drain plug’s tail piece. Pulling the pivot rod from the tail piece releases the drain plug and allows you to remove it from inside the bathroom sink.
Insert a universal pop-up drain plug into the drain hole inside the sink. Insert the pivot rod back into the sink drain. The end of the pivot rod threads through one of the openings in the universal plug’s tail piece.
Screw the retaining nut back onto the sink drain to secure the pivot rod. Test the replacement pop-up drain plug by pulling up on the stopper-rod lever connected to the faucet. This causes the drain plug to close the sink drain. Pushing down on the lever opens the drain.
Loosen the clevis screw. Slide the clevis either up or down along the rod if the pop-up plug doesn’t open the drain fully or seal the drain when you move the lever. Tighten the clevis screw when you are satisfied with the pop-up drain plug’s positions.
