I am trying to reroute my upstairs bathroom pipes away from the
exterior wall (actually an enclosed space behind a kneewall).
They currently run in an inside (room dividing) wall until they hit
the rear wall, behind which is the "crawlspace" open to the rafters
and such. The pipes froze once back there, and its a horrible place to
work in (mice love it) so I want the pipes out of there. Anyway they
turn that corner and then branch in the "crawl space" to the toilet
and bathtub. Below this bathroom and crawl space there is a false
ceiling, that I would like to run the pipes through instead.
But the only way to do that is to drop them straight down inside that
interior wall until they clear the joists below, then running them
under those joists above the false ceiling to where they need to go.
Going through the joists would be preferable, but I cant see how it
can be done-with 16" centers I dont see how to drill through them. But
the hardest part of all is just getting the pipes down to where I can
see them and work with them. Directly below the wall they are in,
there is an extension of that wall into the upper foot and half of the
lower level. This forms one "side" that the false ceiling is hung
from. Its like they knocked out a wall and left just the upper
portion. Does this make any sense? Its hard to describe. But I just
cant see how I can get the pipes down through that so they are below
joist level, without demolishing part of that wall so I can see wtf
I'm doing. Any ideas? I'd sure like to avoid calling a plumber but I
may have to...

Hi,
How about insulating the space/pipe with spray foam?

Sounds like a lot cheaper and easier solution. They even have
extender poles so you can put a spray can at the end of a 4' pole and
control it by your hand to reach into spaces that you can't get
directly to. Paint stores carry them, but anything that has a
standard top will fit into these extender poles. If you can get
within 4' of where you need to spray the insulation, the foam in a can
is great. Don't get the super expanding foam though, as it really has
a lot of force when it expands and it might bend/break/crack a wall.

Well the full space is quite large, so I dont know how practical that
would be....and what do I do if I have to get in there for some reason
and its filled with foam? I'm leary of non-reversibility.
There is one other possibility which might be easy but ugly-I could
run the pipes above the floor, along the inside of the outside wall
(this would be behind the toilet) and then under the tub to its
faucet, but this would leave about 2' of pipe just dangling out
there. This doesnt bother me but it might bother a potential buyer...

---------------------
Based on everything else you have written so far, I think you should
probably just go ahead and do that. It seems like you really want the pipes
on the inside and accessible, and that would solve both of those issues. A
pipe along the wall, near the floor, behind the toilet seems like nothing to
me. You could paint the pipe(s) the same color as the wall or baseboard and
it will look fine. You said, "under the tub" -- do you mean under an
old-fashioned claw foot type of tub?
As far as buyers, I doubt that 2 feet of pipe going along the wall near the
floor behind the toilet is going to make or break a sale. And, since the
temp goes down to 40 below in your area, some buyers may like the idea that
the pipe will be inside and accessibole for the same reasons that you do.
And, if you are really concerned about buyers, you really need to figure out
a way to get rid of the mice and rodent droppings that are infesting the
area that you don't want to go into. A home inspector will find that huge
(in my opinion) problem if that area has an access door where he/she can
enter or look into the space.
Good luck.
