: I have a Kohler bathtub with a twist n close drain stopper that has rusted. I want to replace it but cant figure out how to remove the old one. I removed the knurled knob on top of the stopper but instead of finding a screw I found an unslotted, smooth pin that the cover spins around. The cleanout flush plate says WATCO and I assume that the drain and flush plate came as a kit, but maybe not. I have a strainer wrench but cant get the cover off! Any help would be appreciated.look around the edge of stopper there should be a small allen screw.
