12 Steps to Fix a Sink Stopper


A sink stopper, by any standard, is a great convenience to a home. However, it is not that hard to damage it. When things go wrong with your sink stopper, you can clog your sink and the result can be breathtaking, though not in the same way as the ones provided by the London Eye. Here is a simple guide on how to fix sink stopper damage.

Step 1: Prepare the tools needed.

Replacement Stopper
Slip Joint Pliers
Adjustable Wrench

Note: Plumber’s Putty has signage in the back that advises they are not good sealants for marble and plastic. So, if your sink is made of those two, consider using a Silicone sealant instead. These are good for all-round bathroom use especially on plastic fixtures.

Step 2: Determine what is wrong with the sink stopper.

It is often the case that some parts of your pop-up only got separated from others. You can fix this by holding the stopper in place to reconnect the gap.

Things could be worse such as parts being badly damaged or deteriorated from rust and are in need of replacement.

Step 3: Get to the actual fixing.

Shut off the main water supply to the sink and prepare a few paper towels and a pan or bucket of some kind.

Remove the P-trap by loosening the P-trap retaining nuts from both sides. You may or may not need the slip joint pliers at this point to loosen them. If your P-trap is chrome plated brass, you might need a pliers or a wrench for them. Place the P-trap into the catch bucket.

Step 4: Disconnect the lifting rod.

Pinch the spring clip together to remove the linkage and slide it off.

Step 5: Loosen the retainer nut of the pop-up.

Twist the brass retaining the nut under the sink using a plier to free the pop-up assembly.

Step 6: Remove the flange.

Move the assembly back and forth to dislodge the flange from the old sealant. Grab the flange with a pair of pliers. Hold and twist the pop-up from below to separate it from the flange. Remove the old sealant and discard the flange.

Step 7: Replacements!

With a sharp knife, rim the sides of the sink bottom. Use a plastic ring and fit the new flange in the hole. Apply sealant to the flange and press it down the sink. Make sure that there is enough sealant that there are no gaps or air pockets. Be careful not to put too much either.

Step 8: Insert the pop-up assembly.

Insert the assembly into the flange without disturbing the finished flange. Screw it in place.

Step 9: Put the body back on.

Holding the assembly so it does not rotate out of position, tighten the nut as much as you can by hand.

Step 10: Load the linkage.

After making sure that the ball and the Teflon ring are in place, slide the linkage into the nut. If your assembly is metal, do not over tighten it as to nut push out the nut.

Step 11: Assemble everything.

Thread the linkage rod through the bottom of the drain plug after you’ve dropped it into the sink. Screw the linkage retainer in place. Place the linkage rod through the lift rod hole with the c-shaped retainer clip to keep it in place.

Check if everything is i place and functioning as it should.

Step 12: Finish up.

Remove the compression washer and nut for the P-trap. Place the nut and the compression washer on the assembly. Fit the P-trap and screw on both nuts in place. Tighten as needed.
