If bending is that much of a concern, why not just use PEX? You'll get
the job done in less time, too.

Sharkbites cost WAY too much, so much that they offset the high cost of the
copper, and I don't know of any other way to make the connections (IANAP).
I don't trust them not to leak at some time in the future. I'm old
fashioned and want metal - solid metal - in my walls. Something soldered
together that will outlast the life of this old house :-)

Sharkbites have nothing to do with PEX.

Really? Then why do they sell them for PEX?

normal PEX fittings.

I used some of those Shark Bite things to repair a 3/4" line at my cabin
that was in a hard to get to location. I was skeptical, but after using
them, and it holding for over a year now, I'm sold on them. A little
spendy, but when you have an odd spot, it's Tinker Toy simple. Bing, bang,
boom. Done.

Twenty years from now I'm going to be a plumber. And I'm going to get
filthy stinking rich replacing all of those sharkbite fittings that
people installed twenty years ago cause they are all gonna leak
bwahahahaha...

Seriously - people are relying on a rubber o-ring to make a seal, and
they are going to seal this in a wall??? Know what rubber o-rings do
after 20 years or so? The more I look into PEX, the more I like it and
the less I like the sharkbite fittings.

Using pressboard for exterior siding was a great idea also. Until it
started to disentegrate ...

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.

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...

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

Ever had a good steam burn?

Kids today, pfft. When I was a boy, we didn't have hot water, so we had to
bathe with the end of a steam nozzle me old man diverted from the boiler.
Sure it'd turn you red and remove some skin, but you sure did get clean!

247 degrees.

What radius?

Let me say that I do not know. I cannot give you a definite answer, but the
variables a 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.

Seems you re still in the planning stage..If you want to BEND, drop the
copper and use PEX..

Faster & cheaper and IMO better

It's not cheaper when you factor in the price of connectors, at least not
the job I'm doing. I was considering PEX and then they showed me the
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
connector I trust. Sharkbites use rubber o-rings to make the seal. Know
what happens to rubber o-rings after 10-20 years? My copper will be sound
when the rubber o-rings have disintegraged and the sharkbites are all
leaking :-)

In my experience, they stay in place and continue to seal. If you take them
apart they usually have to be replaced though.

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 :-)

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...
