Hi all

We are doing a basement reno and need to replace the old city water
supply line which is currently running under the ceiling joists
(perpendicular). We have to either run some sort of flexible pipe
through the joists or figure out how bend copper to get them into the
joists. This is all because of a ceiling height requirement where we
are unable to have a dropped ceiling. Can't even spare a 1/2 inch
because of code...

Are there any good options for flexible plastic supply lines now? What
other things should I be considering?

Thanks
Gary
