Sharkbite brand comes with a Cancer warning, so best not used for potable water.

As the owner of a home over 100 years old, I have had better luck with Copperloc over Sharkbite.

IMHO, the only advantage of a Sharkbite over Copperloc for non-potable water is that they can be removed and reused.

Copperloc is better for leak free.
