More important is the type of bender you use. Depending on the radius, it
can go 180 degrees. A slight kink though, can cause damage to the wall and
failure.
Stormin Mormon
(it's been years since I needed to know this) is soft, and
comes on rolls. L, and M are rigid and should not be bent if
possible.
Of course, the goal is to bend it as little as possible.

Better keep it pressurized. Under "normal" conditions water at 247F (or C,
or even R) would be steam.

I have a tendency to use refrigeration grade soft copper for
everything because I can bend it and form my own fittings
with the tools I have. I rarely purchase couplings or elbows
since I can make my own.

*Several years ago I worked on a job with an old timer plumber who mostly
bent his copper pipe instead of using elbows. He told me that there is one
grade of pipe that is used for bending, but not all plumbing supply's
carried it. He also had the proper benders for copper pipe. I don't
remember what the pipe was called.

K, L and M are wall thickness grades (like sch. 80, 40, 20) and have
nothing to do with hardness. Both soft copper and hard copper are
available in the different grades.
Refrigeration grade tubing is yet another thing, and mostly refers to
the fact that the tubing has been cleaned and capped to keep out
contamination that could damage refrigeration equipment with small
orifices, etc. Plumbing grade tubing isn't cleaned and capped since
water pipes can be readily flushed of impurities. Refrigeration grade
tubing is also specified by it's outside diameter vs. plumbing which is
specified by nominal ID.

If bending is that much of a concern, why not just use PEX? You'll get

It may also be added that tubing bending can be improved by the use of
filler sand and pressurization to keep the outer walls pushing out. Of
course, this is only offered in the advance copper tubing bending course. I
would suggest to the OP and whoever else wants to bend copper to invest in a
good bender, or pick one up used whenever they see one. Or even make a
simple one. It makes for a much better job, and reduces failure rates.
Definitely not for the baling wire and bubble gum brigade.

You can bend soft copper as long as it doesn't kink. It is not code to heat hard
copper to get it to bend, as I understand it, and it won't bend well without
that.

How do you know it was correct? The OP omitted any details such as if
soft or hard copper tube was being used.

Is there a "proper" bender for copper pipe? I have a bender made for 3/4
conduit, can that be used to bend copper?
Zootal
> In article <Xns9D1AE937BE973no...@216.196.97.131>,
There are a few places where it has to snake around a bit. Maybe a 10
degree bend here, maybe 5 degrees there. Not much, but I don't know what is
"too much". If bending is evil, I can simply use some 135 degree "elbows"
(what do you call the 135 degree bent couplers?) to make the necessary
bends. I bit more extra work, but I'm happy to do that instead of stressing
the pipe.
I'm using thicker stuff that is "approved" for being used behind walls, I
forget the letter designation that goes with it.
My bender is for 3/4 conduit - can that be used with 3/4 and 1/2 copper?
In one place I have two hot water connections and three for cold water.
Whoever did this ran five 1/2 pipes up through the floor (and my girls
complain about what happens to the shower water temp everytime someone
flushes the toilet). I see no reason not to run a set of hot/cold 3/4 pipes
up through the floor (two pipes going up, not five) and then tee off as
needed once I get where I'm going. Simpler, cleaner, uses less pipe.

@c4g2000yqa.googlegroups.com:
Sharkbites cost WAY too much, so much that they offset the high cost of the

We got that fixed with a Delta faucet that automagically adjusts the hot &

I do more HVAC and refrigeration work than plumbing so the pipe I
have on hand is refrigeration tubing. In order to get me to do any
plumbing work, you have to point a gun at me or torture me by the
crinkling a stack of hundred dollar bills in front of me ploy.
TDD
Steve B
Let me say that I do not know. I cannot give you a definite answer, but the
variables are: diameter of the tubing; copper alloy you want to bend; if
you fill the copper with sand or not; if you pressurize it or not;
temperature of the copper; type of bender; whether it is a plain one die
bender or one with a mandrel (two piece); how fast you make the bend; and a
couple of other things.
I'd Google and get some copper suppliers and people who really do this a
lot, and use their answers.
For most home repair apps, a simple bender is better than no bender. But
the technique will affect the results greatly.
Lastly, how critical of an application is this? IIRC, you did say it was
for 60 # water line. Make your radii as big as you can, even if it means
adjusting elsewhere for the bend. If you just really have to have a tight
90, buy a compression fitting or sweat a 90 on there.
Get some scrap and play with it. Realize the scrap may not have the same
properties as new, but it will give you an idea about the failure points.
I'd do it in a warm room, and not a cold garage, or outside in the snow.
Use a heat lamp or similar to warm the copper before bending.

Can one safely use an EMT bender on copper pipe? My guess is "no", but
don't know for sure.

Why do they call them 45 degrees? Look at one - it's not 45 degrees,

Yes, I know that. I also know that if you go to a plumbing supply house and
ask for a 135-degree ell they will tell you there is no such thing.
There are similar fittings known in the trade as 22.5-degree and 60-degree
ells; what do you suppose are the actual angles of those?
Zootal
Hmm...the 22.5 is probably 157.5 degrees because why would you want such a
tight angle? Or how often would that actually occur. I didn't know they
made those - the only ones I've seen are the "45" degree bends. The 60, my
first guess would be an acute angle of 60, but that is a pretty sharp bend,
so the 60 is really 120 degrees?
I'm guessing that the true angle of the bend is (180 - <the numbernumber>),
not zero plus the number. So a 90 is 180-90=90 degrees. A 45 is 180-45=135.

That's not the right type of bender for copper. If you feel that you
want to try it anyway then just pack the tube full of sand before
bending.

It's not cheaper when you factor in the price of connectors, at least not

seriously holy crud overpriced connectors. I decided to use copper instead.
I'm still not sold on PEX. The tubing may be good, but I have yet to see a

They haven't been around long enough for anyone to really know for sure
what will happen in 20 years. I hope I'm wrong, but it just seems to me to
be really stupid to put something in a wall that uses a rubber o-ring to
make a seal. I've got connectors here and there like this (that use a
rubber o-ring to make a seal), mostly for my well and garden, and they all
have one thing in common - they all leak after a while.
Time will tell - I'm still thining of becoming a plumber in 10-15 years.
Just in case I'm right :-)

You should NOT be bending 1/2 or 3/4 copper piping... You need to
route
the piping by using the proper pipe fittings...
Bending piping weakens it and with the quality of water and the amount
of
chemicals in it, you don't want to create a weak point where it will
fail as
it begins to corrode on the inside... Also you want to take care not
to use
too much flux before you solder, any solder that gets INSIDE the pipes
will
pit the inner surface of the pipe and create a spot which will fail in
the future...

Well the question here is: What sort of shower value do you have
installed ???
Is it a scald protection temperature balancing type ??? If it is,
your cartridge
inside the valve body might need to be replaced due to build-up of
crud from
hard water conditions... If it isn't one, meaning you have an older
home with
the individual hot/cold water valves for the tub/shower, then you
might want
to consider installing a new scald protection shower valve...

LOL... The cost of PEX isn't in the tubing or the end adapter for the
copper
pipe stub at the fixture, it is entire with the TOOLS you need to work
with it...
You need a special tubing cutter to make cuts that are just right...
You need
the tubing expander to stretch the tubing to insert the end
fittings...
If you are making connections of PEX tubing INSIDE your walls you are
missing
the point, PEX is supposed to be run in an unbroken manner from
distribution
manifold to the fixture connection without any breaks or connections
to extend
the length of the tubing run inside the walls... PEX is supposed to
be run as if
you were pulling communications wiring in a homerun or "star
topography", and
NOT in the same manner you would run copper pipes from device to
device...

It's one of those constant volume valves, where you can't control how much
water comes out. I hate it. I like to control water volume, so I replaced
it with extreme prejudice :-)
