The bathroom sink drain was clogged, probably with hair. The tenant poured some combination of baking soda, vinegar, and boiling water down it. Shortly afterward the bottom of the metal U-shaped drain pipe beneath the sink in the vanity cabinet developed a hole. The vanity full of useful and not-so-useful items was flooded. Could this combination of ingredients have caused the metal pipe to corrode. I don't know what kind of metal it is.
