[oldE]

I have used sharkbite on a copper pipe when I removed an old water heater from a restricted space. The new tank was in a different ( read:accessible) location. All I had to do was block off the feed to the old tank. I didn't want to solder in that tight space, so prepped the cut off end and jammed the fitting into place. That was three years ago. If I ever remodel that old bathroom and utility space, I will probably rip out a bunch of old, unused pipe and solder in plugs where appropriate. The structure in that part of the basement was practically built around the plumbing.
