I had a similar setup with my shower valve. At Home Depot I found some
fittings that converted from cpvc to the metal valve body. The best thing
about them was that they screwed together with a connection similar to a
water hose, so you wouldn't have to worry about twisting your cpvc if you
had it too loose when you made the initial connection.

Looks like this.

I have a4 port shower valve body I am connecting CPVC (1/2") pipes
to.

The shower valve is solid brass with all four ports being 1/2"
F.I.P. It
also comes with four 1/2" brass nipples. So I can get four
1/2" CPVC M.I.P.
transition unions (slip CPVC x brass) and screw them directly into the

valve body. Or I can screw the 1/2" brass nipples into the four
ports on
the valve body, and get four 1/2" CPVC F.I.P. transition unions
and screw
them onto the other end of the nipples. Is there any advantage of
doing it
one way versus the other?

I have another question regarding an outdoor shower. The pipes are
being
routed on the inside "side" of the 8" exterior concrete
wall. The pipe runs
up to about 72" above ground, then I drilled a hole through the
8" wall. I
know on the other end I need to secure a shower arm that is 1/2"
male, but
how do I make the transition from CPVC pipe to the shower arm? If it's
an
interior wall I would have studs there and will put in a brass drop ear
90
set a little back from the finished wall. But this is exterior wall,
so I
think perhaps I put in a CPVC elbow then continue with the CPVC pipe
through
the wall and around 3 inches from the finished exterior surface, change
to a
transition union (slip CPVC x brass) F.I.P. with the brass end flush
with
the finished wall? Is this the best way to do it? When I screw in the

shower arm, will it end up breaking or twisting the CPVC pipe if I turn
it
too hard? Or do I need a drop ear 90 that mounts on the inside?

Thanks,

MC
