Once again, the black bathroom sink drain stopper stopped popping up. Having had this happen once before, I knew what I would find:
The lever arm to the left of the ball should be about twice that long, minus the jagged end.
I slid the ball rightward to expose more rod, introduced both ends to Mr. Bench Grinder to round them off, scuffed up the short end with sandpaper to improve its griptivity, then slobbered on enough JB KwikWeld to cover the entire length of rod that will live inside the drain:
The first failure took 9 years, this one took 4…
Memo to Self: Next time, replace the rod with something that doesn’t corrode.
