Step 7 · Reinstall Stopper and Test for Leaks
Reinstall the tub stopper mechanism by reversing the steps you took to remove it. Screw the central post back into the cross-piece, then attach the top knob. Before using the shower, perform a leak test. Close the newly installed stopper and fill the tub with a few inches of water. Let it sit for 10-15 minutes and check for any signs of leaks around the drain (if you have access below) or simply observe if the water level in the tub has dropped. Then, open the stopper and let the tub drain completely, again checking for any leaks while the water is flowing.
