Fix a clogged tub drain quickly and easily by removing the stopper and fishing out the hair and gunk that causes the problem 80 percent of the time. We show you how to open most common types of drains.
Follow our series of photos to determine which type of stopper you have and how to remove it.
Clearing a Drop Stopper Drain
The most common type, a drop stopper, has a setscrew located under the cap.
Photo 1: Lift the stopper and loosen the screw on the shaft slightly. Slide the stopper off the shaft.
Photo 2: Hook clogged hair with a bent wire and pull it out.
Push/Lock drain stoppers
These stoppers lock and seal when you press them down and release when you push down a second time. The way to remove them isn’t so obvious. In most cases you have to hold the stem while unscrewing the cap as shown. With the cap off, you can sometimes fish out the hair from the crossbars. Otherwise simply remove the entire shaft by unscrewing it. You may have to adjust the screw tension on the stem when you reinstall everything to get a good seal.
Push/Lock Drain Stopper Removal
Hold the stopper shaft tightly with a finger and unscrew the top.
Many tubs, certainly most older ones, have a stopper located inside the drain and overflow tube. Most of these have a lever on the overflow plate and a screen over the drain. The screen keeps most hair out of the drain, but some gets through and eventually forms a clog at the crossbars. Simply unscrew the screen for easy access to this clog and remove it as before. If the drain has an internal stopper, simply unscrew the overflow plate and pull the linkage and stopper up and out. Then clean the linkage and stopper and run water down the drain to flush it out.
Occasionally the linkage is out of adjustment and the stopper doesn’t open far enough from its seat to allow a good flow. Adjust it, reinsert it and test it. Run water into the tub. If it leaks out, lengthen the stopper linkage to seal the drain better. If the drain doesn’t open to let the water out, shorten the stopper linkage.
Levered Stopper Removal
First remove the screen and clean the crossbars. Then unscrew the overflow plate, pull out the linkage, clean the stopper and linkage, and rinse the drainpipes. Readjust the linkage if necessary. Reinstall the assembly.
