How to Replace an Oval Bathroom Sink Drain

Replacing an oval bathroom sink drain is a straightforward task that can be completed in a few simple steps. This process requires you to understand the different components of the plumbing system under your sink, which involves identifying pipe fittings, stoppers, and washers. Before beginning, gather the necessary tools and materials, including a new drain assembly, adjustable wrench, pliers, and plumber's putty or silicone sealant.

To replace the drain, start by turning off the water supply to the sink and draining any remaining water. If your sink has a pop-up stopper, remove it by unscrewing the cap and lifting out the stopper mechanism. Next, use an adjustable wrench to loosen the drain flange, which is the metal ring around the drain opening. Disconnect the drain assembly from the sink by detaching the P-trap, which is the curved pipe that connects the drain to the main drain line.

Clean the sink's drain opening thoroughly to remove any debris or old sealant. Apply a bead of plumber's putty or silicone sealant around the base of the new drain assembly and insert it into the drain opening. Tighten the drain flange using the adjustable wrench, ensuring it creates a watertight seal. Reattach the P-trap to the drain assembly and hand-tighten the nuts.

Reconnecting the pop-up stopper assembly involves inserting the stopper into the drain flange and tightening the cap. Turn on the water supply and check for leaks around the drain, P-trap, and stopper. If any leaks occur, tighten the connections or reapply sealant as needed.

By following these steps carefully, you can successfully replace an oval bathroom sink drain and ensure proper drainage.
