Step 5 · Install the New Gasket

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Take the new overflow gasket and position it correctly. Most overflow gaskets are tapered or beveled. The thicker, wider side of the gasket should face the bathtub wall, and the thinner, tapered side should face into the drain opening, towards the overflow pipe. This wedge shape is designed to create a compression seal when the cover plate is tightened. Press it into place around the opening.
