I've just bought a 15 year old condo apt. It was rented out prior and
was in fairly tough shape. I've been working on replacing a broken wall
tile in the tub and just noticed that the strainer is missing on the drain.

The tub seems to drain alright but I'm wondering why that strainer would
go missing. From what I've been told those strainers just spin out, but
I'm thinking that they may hold the drain up to the base of the tub.

Any help/advice appreciated.
