Ask a Question
  • My sister discovered an ant colony living in her toilet tank lid (yuck!) - they apparently got in through a small hole in the underside of the cover. Now we’re wondering why the tank lids even have holes in them (mine has 2 slightly larger holes while my mom has a similar small hole in her’s). My search of the interwebs has come up empty - any chance you know? It’s one of those trivial questions that will drive you crazy and your help is appreciated!

    Some toilet tank lids are hollow-body and some are solid-body. On the hollow-body ones, there will be one or two holes. Sometimes on the bottom, sometimes on the back edge. They are part of the manufacturing process and have no user purpose or mechanical function. They are vent holes for drainage during manufacturing. Once formed, vitreous china plumbing fixtures (primarily toilets) are kiln-fired at 2,200 degrees to create the final glass-like surface. During this firing, the clay shrinks 12% and expels its moisture. The moisture and steam vent out through the holes.  In the link below, Kohler Company talks about the holes in bowls and tanks. Tank lids are not mentioned, but the concept is the same.
