How to Fix a Bathroom Sink Plug

Updated February 21, 2017

A bathroom sink plug is comprised of two parts: a pop-up stopper and a mechanism that raises and lowers the plug. The stopper may begin to malfunction such as getting stuck or not closing or opening all the way because of loose parts. If your sink plug is having some of these problems, it may be less expensive to try to fix the stopper rather than purchasing a new one.

Crouch beneath the sink and locate the pivot nut behind the drain pipe if plug is not closing all the way. Occasionally, the pivot nut loosens and can be tightened by turning it clockwise with a wrench. Be careful that you do not over tighten or the sink plug could get stuck.

Locate the metal horizontal bar that extends from the pivot nut beneath the sink. If the above steps did not solve the problem, adjust the screw that connects the lift handle to the horizontal bar.

Twist the screw on the lift handle in a clockwise direction with a flat screwdriver to tighten. Again, do not over tighten or the stopper could be difficult to move.

Insert the metal bar into the hole in the base of the plug if the bar has detached itself, which could keep the stopper from moving. Once the bar is secure, tighten the pivot nut with a wrench. You may need to loosen the pivot nut with a wrench before you connect the bar.
