According to TURTLE :

The choice is your , but here is the way I think.

If you had a Mad Dog out in your front yard and you had to choose between
two
material of a stick you want to use to go out and beat
the hell out of the mad dog with . Copper or Plastic ?

I could picture the ASTM standard specifying _that_ test...

You can picture my choice.

Copper supply pipe makes a lousy club. One hit, and the pipe
is kinked. Second hit (if you're lucky the pipe hasn't kinked
at your fist), you have two shorter pieces of pipe and a ****ed
off dog.

PEX or PB pipe makes a better weapon. Hint: it won't break.

Iron pipe, on the other hand...

Though, if you had time to sharpen the end of the copper pipe,
it might be useful...

Interesting criteria - have you plumbed your house with baseball
bats?

This is Turtle.

I see you don't do much plumbing do you.

I've seen some copper joints with a greenish ick around them, sometimes
culiminating in a 3-dimensional chunk of chalky ick. What is that?


That ick comes from electroylisis, which in the plumbing world, happens
when two different types of pipes come into contact with each other, and
the results tend to show up at the joints, as you noticed. Most often
happens when someone uses tin/galvanized hangers to tie the pipes to
wood structure, or lays conduit right over the copper pipe without
sticking a piece of wood shim or cardboard or hunk of foam or whatever
to prevent direct contact between the two un-like pipes, or when someone
replaces a section of copper pipe with galvanized without using a
dilectric union, which is made of plastic, rubber and brass (brass
doesn't react with other metals, which is why brass is used for pipe
fittings).
