I am finishing a remodel as a homeowner although I have done most of my
rough plumbing. But I am wondering about the angle stop connections. I
used L copper and want to install my angle stops inside of my new custom
made cabinets! I don't really want to solder for obvious reasons and was
going to use compression fittings but I have read that compression fittings
are not recommended for type L rigid copper, only type M. If I don't solder
and can't use compression fittings, what do I do, use a copper epoxy??? Is
it a hard and fast rule not to use compression fittings with type L copper.
I guess I could use a mini torch or something. Not sure what to do. Also,
is the standard supply hose 12" for toilets and, 18" for sinks?? Help if
you can!!

Where did you read that?

About 6 months ago I used epoxy on two joints where a torch would have been
awkward, yet a leak wouldn't have done much damage. It was easy to apply
and has held up so far, though my maximum pressure is only 40psi so it might
not be a definitive test.

I haven't any idea about compression fittings on type L, but then again I
haven't used a compression fitting except where it came as a component.

Why would a compression fitting be any less reliable on L than on M? The
o.d. is the same. I use compression fittings on L, M and K and have no
problem.

Same here but this thinking is because some dummies mistakenly think
compression fittings have to ruin the tubing to seal and K & L not being
crimped very easily won't seal.
