Gals or guys, please add your tips to this thread that we senior women might be able to do for ourselves with basic tools. OK, I have been fussing about my tub/shower not draining right for months. A plumber tossed out an estimate of $500 because he felt the entire drain should be replaced. It is 47 years old. This morning I took it apart and pulled the entire shebang out and it all made sense. The weight of the old brass stopper and 47 years of flicking had worn the cam down. A simple replacement lever assembly was all that was needed. I found it at the hardware store for $10. Tools required: Pliers, screwdriver, and a small adjustable wrench. Here is the repaired unit before installation. It drains fast and furious.
