Remove the two screws holding the overflow cover in place using a flat-head screwdriver.
Remove the overflow cover. Do not pull hard because the drain stopper is still attached by the linkage. Pull the stopper out of the overflow drain tube.
Examine the drain lever. If it is rusted or stuck in place, try to remove the rust with a wire brush. Lubricate the lever with silicone grease. If this does not work, you will have to replace the overflow cover and trip lever with a new one.
Ensure that the stopper links are in good condition and free of rust or other weak spots. Replace if necessary. Make a note of the length they are set at so you can set the new links at the same length. Tighten the lock nut in place.
Check the drain stopper. Clean off any gunk or debris. Lubricate thoroughly with silicone grease.
Lower the drain stopper back into the overflow tube.
Replace the overflow cover. Secure in place with the screws.
