How to Repair Tub Drain Linkage Assembly

The tub drain linkage assembly is the device connected to the bathtub drain stopper, which prevents the water in your bathtub from draining. The assembly is located behind the bathtub wall and is not clearly visible, but it is easy to get to. Learn how to get at it to repair or replace it, if necessary.

Save the plumber's fee and fix the linkage assembly yourself.

Step 1

Remove the two screws from overflow plate. This is the silver plate, with the lever that moves up and down, in the wall of the tub above the drain. Pull the overflow plate forward.

Step 2

Attached to the overflow plate is the tub drain linkage assembly. It looks like an old weight and lever type of system. There are two individual bars connected to one another and a cylinder weight at the end. The linkage assembly connects to the overflow plate. You may have to wiggle the assembly around so that it clears the overflow plate hole in the tub. Pull the overflow plate and linkage assembly out.

Step 3

The linkage assembly is connected to the overflow plate by a cotter pin, which is inserted in a small hole in the linkage assembly and another hole in the overflow plate. Using a small pair of pliers, gentle pull the cotter pin out of the hole. The linkage assembly will not be disconnected from the overflow plate.

Step 4

The new linkage assembly should have a new cotter pin. Use the new cotter pin to connect the new linkage assembly to the overflow plate. The linkage assembly is adjustable to fit the length of your bathtub. The top bar on the linkage assembly will allow you to adjust it up or down to fit properly.

Step 5

Once the linkage assembly is connected to the overflow plate, gently insert it into the overflow plate hole in the tub. Slowly allow the linkage assembly to fall into the overflow tube. Once the linkage assembly is in place, reconnect the overflow plate to the tub.

Step 6

Move the lever up on the overflow plate, turn on the water and allow some water to enter the bathtub. Check to be sure the water isn't seeping down the drain. If it is, repeat the procedure, allowing the linkage assembly to drop further down into the overflow hole.
