Plumbing epiphany

Whilst walking the dog I realized that I really don't need to fix that pipe going to the second floor.  It's a dumb place to put a pipe anyway, going up through the wall between the parlor and the entry hall, under the front bedroom and above the stairway, then along the middle of the house, taking a right turn at Albuquerque to the upstairs bath.  How it gets to the blue room bath I don't yet know.

What I realized is that it would be just as good to take a pipe upstairs from the kitchen to the wall between the blue room bath and the main bath.  This would solve the entire problem.  And since my goal is to install on-demand water heating, there's no real reason to run two pipes, either.  Less to break is good.

So there's the reason to have a dog.  Walking her gives you time to think.
