I remember growing up that all that was needed to remove the stopper on a rod and plunger style stopper was a quarter turn, which disengaged the stopper assembly from the rod. We did this in my house as normal cleaning maintenance. Why has the design changed on pop ups so that you can't remove the whole gizmo to clean out the drain. I don't know where else to pose this question so came to you guys. I can't believe there has been a regression in design without a good reason. BTW we lived in that house for over 20 years and the stopper never broke or wore out.
