My tub would neither hold water nor drain properly. I used silicone grease on the face plate, which freed up the lever, so my tub drains well. This did nothing for the water leakage, so I also replaced the weighted drain assembly inside the pipe, and adjusted both the old and new assemblies millimeter by millimeter. No luck. The tub still won't hold water. I can feel the weight hit the lip of the overflow pipe bottom (I think), but at best I get a slightly slower loss of water. I would really appreciate any suggestions. Thanks!
