Water – What can cause a sink’s pivot rod connector to leak water

leaksinkwater

Background: When running water in my bathroom sink, I'm seeing a small water leak (about a drop per minute). I traced the source to the bottom of the pivot rod connector – see the red circle in the attached picture.

Questions: Given that the leak doesn't appear to come from where the connector itself is screwed in, what might the cause be? Can water still be reaching the pivot rod itself?

what might the cause be?

  • The connector isn't tight, so the pivot assembly is loose, so water can work past the seals.
  • It was assembled with dirt in the seals
  • A seal has failed or is damaged
  • Something else.

Can water still be reaching the pivot rod itself?

Yes.

I would disassemble, clean and inspect. replace any worn or damaged parts - especially rubber/plastic seals around or in the pivot assembly. Reassemble and test.
