I didn't notice any soft spots that wanted to kink when I was pulling
them to the side to get to other things.
I was asking because these will be under the tub far enough that they
will be hard to get to if something happens. This is an upstairs
bathroom. but it won't be used much and I might even turn the water
off to the upstairs most of the time.
Thanks, David

In such situations, where something won't be accessible after the work
is completed, and getting to it for a repair would be problematic, the
thing turns into a Wallya. Wallya at it, might as well replace those
pipes. Copper corrodes from the inside out, and as someone else
mentioned, the first signs of a problem is some green patina spots
showing up, usually near the joints where someone was liberal with the
flux. So, I have to disagree with Bill's assesment. If the patina is
more or less uniform on the pipe, fine, but if there are localized
green spots with white stuff around, then that's a bad sign. The pipe
has corroded from the inside and the change in patina somehow
indicates thinner material where the pipe has eroded. This seems to
happen more in fittings and probably has to do with turbulent flow or
some such and/or excess flux.
Sharkbite fittings work great, and they are rated for burial in slabs,
but I don't know if they'd be my first choice if you're going with
copper pipe. I don't doubt the Sharkbite fittings would work, but I
just like the purity of copper with copper. If you're transitioning
to PEX the Sharkbites make it trivial - one of their best points. You
can work with copper, PVC or PEX with the same fitting, which makes
them indispensable in the repair kit. If you are concerned about them
being buried for a long while over occupied space below, run an air
pressure test. Hook up a fitting and pump it up to double your house
pressure and let it sit overnight to see if the air pressure is
dropping. If it holds at double the pressure, it's unlikely you'd
ever have a problem. They probably would be fine, they seem very well
made and they work better than the competition that I've tried, such
as the Zurn plastic stuff. Pretty funny, eh? I have no problem with
PEX supply piping, but plastic fittings give me the heebie jeebies. I
have had issues with the Zurn fittings before, so I just stopped using
them.
