Hey everyone, thanks for playing the game. Glad to see so many of you liked it. Couple things:
If you screwed up on the pipe in the bathroom there is a release valve in the basement that will drain it so you can start over.
Getting the badge has nothing to do with the fuses, I think Kong put that in there as a hint to beating the game overall.
And the badge has worked just fine for me and for the Kong staff so we're a little stumped (but looking into it).
