I need to agree, with the above. Not a fan of the bite fittings, or push fittings in general. I had a bit of a bad experience. For anything permanent i started a to use a lot of stainless steel press fittings www.swiss-fittings.com/fittings/pressfittings , most of the larger brands like www.viega.com, offer these, ProPress, GDPress, etc..
Most of the bite fittings are still not offered in stainless steel, and in the applications that I would possible use them for, i mainly work with stainless steel pipes. Only exception and alternative to shark bite fittings are VSH Tectile fittings from Seppelfricke. Difficult to get in the United States though.
