If you are only talking about 1 or 2 closets, it would probably just be better
to swap it out for a 1’ piece of 1” steel pipe with an elbow , transition to

Just remember to allow for thermal expansion and contraction. It can get very
ugly if the CPVC is restrained and thermal expansion and contraction has not
been appropriately allowed for. This applies when a building is warm in the

I would agree with CPVC because of the manufacturer listing. However, if

Really no different. I doubt you will find longitudinal bracing listed for
cpvc. You will have to put a short branch (same size as main) perpendicular
to the main and brace that with a lateral brace to act as your longitudinal
brace on the main.

I'm about to do my first CPVC sway bracing calc's. This is in CA (a first
for me as well), north of San Francisco.
Are there any special issues that I need to consider, or do I approach this
as if it's not much different than if it where steel?
Thank you,

Hey Tom.
Yes, some.
I have had long attic runs before and I guess that is what I am envisioning.
Pipe "breathing" as it were. The listed CPVC hangers allow the pipe to move
freely for expansion and contraction. Down south, there are some big temp
differences.
If we lock i
Matt,
I understand that expansion loops are not that common. A layout usually
provides enough offsets and changes in direction where long runs of CPVC pipe
are not that common. But, they do happen.
Where the straight CPVC run is sufficient length to require an expansion loop,
provide bracing

Hello Matthew,
There are several ways shown in the manual about putting in offsets, making a
corner, and I think it even shows the sizes n
of CPVC to expand when we have hard strapped
it to wood?
Never braced CPVC so more curious than anything.

Reading the Tech Update got me thinking.
What do we do to address the need of CPVC to expand when we have hard strapped
it to wood?

The primary answer has already been provided but thought it worth adding -
unless it has changed recently, you’ll won’t find any longitudinal braces.
You’ll be using lateral brac

My installers are trying to install EQ bracing on CPVC for a NFPA 13 system
and aren't having much luck..they said that the fittings are gouging and
digging into the CPVC (and no they are NOT using impacts) Anyone out there
with some experience on bracing CPVC? This project was designed off
