Heck, I learn something new every day or I consider the day wasted.
But I have owner contracted a 3,000 sf house, remodeled five, own four, and
currently maintain two. Was a contractor for nine years.
I've been around the block so many times, I'm still dizzy.
Naawww...this newsgroups is awesome. It is easily one of the
most polite and informative groups out there. Drop in on some
of the alt.windows... groups. It is amazing how many
adolescent children with absolutely no control over their
mouths are ranting and raving over usenet. I used to think
that I'd slap my kids silly if I caught them behaving like
that. Now it's more like I'd shoot my kids if I saw them
behaving like that...
Copper pipe comes in hardness grades. K, L, and M. K copper
(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
Of course, the goal is to bend it as little as possible.
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.
I've done that. Someone ran 3/8 soft copper under my
trailer, for the water line. The copper rubbed through at
some point, and started spraying. Find out that 1/2 OD
refrigeration works well. Silver braze works, too.
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.
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.
I do whatever work I need to do, in the interest of knowing the job was
done correctly, as well as being more self sufficient and saving a few
bucks. If it gives me an excuse to buy new tools, even better.
I have a hard time understanding modern man. There was a time in this
great country of ours when people were self-sufficient. Everyone knew
how to obtain food in one form or another, take care of their dwellings
and transportation and they never stood in line for anything. Technology
has bounded forward but that doesn't mean a single person can't deal
with most of it. I was talking to a doctor friend the other day when I
remarked that I can understand and repair just about anything except the
human female. *snicker*
Ya gotta love em anyway. One of my grownup girlfriends voted for
Bill Clinton because he was pretty, she didn't like the way the
other guy looked. Besides, fixing women would destroy any of the
limitless entertainment value they possess. My only problem is
that I can't tolerate the crazy ones because I refuse to be abusive.
Some people live for conflict, it excites them. Not me, I like
peace and quiet.

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
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.
