I've always used copper. Very durable and strong. If I have to change
something, I solder them together, ready to go, no waiting for glue to dry.
However, gluing is admittedly faster and easier then soldering, and modern
pvc glues dry in full strength in a few hours. How strong is cpvc? I'm
afraid I'll accidently hit the pipe and break it, or twisting it when I
thread a fitting on and break it. I keep thinking of PVC, which is
Well plastic wouldnt get ripped off!
My dad used to rent homes in phoenix, he had to go all plastic since
tenants would steal the copper pipes and everything else of value out
of the homes....
with todays high copper prices people are finding their gutters
downspouts and other copper stuff has grown feet and left the
Plastic is safe at least for now:)
They call it "wet or dry".
Irrigation techs usually turn the pumps back on as soon as they can
walk back to the switch. They say it is good in 30 seconds but I think
a couple minutes is a better number. I know you can't pull a pipe
joint apart after a minute or so.
Yes, and not just the blue stuff. A big advantage of PVC/CPVC is the
ease of repair and modification. It is flexible enough that given a
few feet either side of the patch it can be cut and a new fitting
inserted. Can't do that with copper (easily).
They were using the wrong schedule PVC then.
I've always used copper as well. In saying that however, I just had to
re-route water lines and install and aerator etc.... I found the selection
of copper fittings to be rather poor and the prices were outrageous. Have
you priced a 10' stick of 3/4 Type L recently? $34! And the fittings
are all running a few bucks on up (each). So I could definitely see the
advantages of CPVC given what appeared to be a better selection of fittings
and much, much cheaper. For the odd bit I do, I'll prolly stick with Cu
but if I were outfitting a whole house, I'd sure be looking at plastic!
ps. I prolly just like copper cause of the torch and such.....just don't
get the same effect with a little stick with glue on it :)
I forgot to add--No, copper will not corrode. There are some houses
with copper lines that are over a hundred years old and still working
fine. The Gothic cathedrals of Europe have copper roofs that are
nearly a thousand years old. It does however allow for build-up of
mineral deposits inside the hot water tubing, that can be a nuisance in
maybe 50 years or so, depending upon how bad your local water supply
is. Use plastic, copper hangers with brass screws, or wrap electrical
tape around the pipe if steel straps are used, as copper will produce
electrolysis and corrode other metals when in direct contact with them.
But copper wont crack when someone bumps into it, CPVC will.
Copper wont sag between the hangers, CPVC does.
Copper dont shatter when a screw on fitting is over tightened, CPVC
Copper dont make the hot water taste like plastic, CPVC does.
I dont consider waiting hours for the glue to dry to be "ease of
maintenance". Soldering is more work, but the pipes can be used a few
minutes after soldering. CPVC needs hours to dry securely and until
them, No Water".

Your union rep teach you that?
You can take a piece of CPVC pipe and pound it flat with a hammer and
not shatter it. U/V damaged white PVC gerts brittle but that is
usually after about 10 years in the Florida sun. People use PVC pipe
for guides on boat trailers and boat lifts here in South Florida. If
it was as brittle as you say it would snap off the fist time the wind
caught your boat. That is not what happens.
Beats me. Never looked. Most pools are below ground so I'd imagine the
piping is below ground.
I'm really going from my own experience of where I've left a couple sticks
of the stuff outside in the weather and within 10 months or so, it was
pretty brown (from white).
