How to Repair a Sink Stopper

With time and use, the parts of a sink stopper may fail, making the kitchen, laundry, or bathroom sink unusable. Sink stoppers can also rust or build up difficult to remove hard water crystals. Rather than replacing the entire sink, it is possible to replace the sink stopper with a new assembly so the sink drain looks good and regains its functionality. Repairing a sink stopper is a job most homeowners can do with a few simple tools and moderate DIY skills. Shoppers can find the parts, tools, and supplies needed to repair a sink stopper online on eBay or at a traditional hardware store.

Replacing a Sink Stopper

Most of the time the sink stopper breaks from wear and tear. It is often better to replace the entire assembly rather than try to replace only a part or two. Replacing all the parts at once can save time as owners can avoid having to repair additional individual parts in the future.

How to Repair a Sink Stopper

Before trying to repair a sink stopper, homeowners should gather a few tools and supplies to make the job quick and easy.

Remove all items under the sink and turn off both the hot and cold water supply to the sink. Homeowners should also gather the tools and parts needed for the job.

Step 1

Begin by locating the P-trap. On plastic assemblies, it is usually possible to loosen the nuts on the P-trap by hand, but with metal traps, homeowners need to use a pair of pliers or adjustable wrench. Place a catch bowl under the trap and remove the P-trap, placing it in the catch bowl.

Step 2

Disconnect the lift rod assembly by pinching the ends of the C shaped retainer clip. Slide the ends of the linkage rod off.

Step 3

Loosen the pop-up assembly retainer nut using pliers or an adjustable wrench. Rock it back and forth a few times to break the old sealant below the finished flange and the bottom of the inside of the sink. Push up on the pop-up assembly, while holding the finished flange with pliers, and turn the body of the assembly below to unscrew it from the flange.

Step 4

Remove all the old sealant from the drain hole in the sink. Apply a bead ofsilicone sealant or plumber's putty around the new flange where it contacts the sink. Press the flange into the drain hole and down into the body of the sink. For a porcelain sink, owners can use plumber's putty but for plastic or marble sinks, they should use silicone sealant. Allow the sealant to dry according to the manufacturer's directions.

Step 5

Insert the body of the assembly into the drain hole in the sink from below, so the fitting for the linkage points toward the rear of the sink, and screw in as firmly as possible with the fingers. While tightening the nut, be careful to hold the assembly in place, not allowing it to rotate.

Step 6

Slide the linkage for the pop-up assembly into the nut. Check to be sure that the Teflon ring in the body of the assembly is correctly in place. If using a metal assembly, tighten carefully with pliers.

Step 7

Place the new linkage rod into its hole catching the loop at the bottom of the drain plug with the rod. Screw the linkage retainer nut into place on the assembly. Put the end of the linkage rod in its lowest position and choose a corresponding hole in the lift rod assembly. Slide the hole over the end of the linkage rod with the C retainer clip.

Step 8

Fit the P-trap by screwing both the nuts in place, tightening until secure and allow the sink to dry.
