My neighbor's got a leak in the hot water line running from the manifold
in her utility room to the kitchen sink. The copper line is in or just
bellow the concrete slab. The plumber has to dig up a substantial
portion of the kitchen floor to replace the corroded line. He's going
to use Copper. Wouldn't it be better to use PVC?


FWIW the Pex heavy duty flexible line is a great solution. Hide it
behind a mop board, etc and don't bust up the concrete

+1 for Pex, I used some to re-plumb hot water lines in the garage.
Much cheaper than copper.

+2, Pex is cheaper, easier, quicker and better.

Grin, My only issue with pex is that I bought a 100' roll of 1" stuff
and it was a pain trying to get it straight. Hot air gun and lots of
bending with arms... ughh. Maybe there's a better way to straighten it?

Cap one end, fill with hot water, lay out straight, drain to cool?
A hot air gun might work, too, but that could pose problems.
Maybe a hair dryer funnelled into the end...

I've only worked with it minimally so far, and the 1" was a beast to
arc. I had to use hot water just to get the ends to go on the
fittings, too. Once it's heated, it's much easier to work with. Of
course, I did the refit on the whole house water filter in the dead of
winter, just so I could experience cold PEX. :-\
