Wow, I've put scores of similar (PEX and "Sharkbite") clamps in my house, which I have re-plumbed. In fact, next weekend, I'm going to use more when I install the new tankless water heater--love those things!
Both MrDangerus, Loren and delomike make excellent
points: the clamps are absolutely fantastic and do not (cannot?
) come off if installed properly (they have a "go/no go" gauge for measuring fitment). Just an amazing way to connect pieces.
However, to remove them can be an ordeal, as the generally available from non-online retailers
clamp removal tools can be unwieldy, and their use assumes you are not working in a tight or restricted space. Sometimes, if you screw up, the "fix" can end up being cutting the hose, removing your stainless (or brass, or plastic) fitting with the clamp still attached, and removing the clamp on the bench to much swearing (or just toss the whole piece and replace with new hardware if pressed for time).
