I'm not sure about doing this, as I had very bad luck the last time I
tried (again, that was with the old toilet that overflowed).

I know this isn't a binaries group, but I have a picture of the inside
of the tank and would like to have someone point out exactly what to do
or not do. Is there a binaries group I can post that to? Or would it be
okay to post it here? (It's a small picture.)
