lol and thanks. You have no idea how confused I get when I do these things. How many ksquareds does it take to change a light bulb. Don't ask. Find someone else.
Remember the simple toilet innards. A flapper and floating ball on a rod? Piece of cake to fix and you rarely needed to fix them.
Then Toto came up with their fancy flush system. Expensive and doesn't take a flushing like the old stuff.
So? Buy a regular toilet next time? NOT SO FAST! All the rest of them copied Toto! Per my plumber this past winter when he was working on my boiler. In the meantime, old faithful flushes on so I'll cross that bridge when I get to it!
