1) well you can't really find the cooper hoses for sale, they are only made in limited production runs about once every 2 or 3 years
2) they are not made from breathing grade materials and will offgas various mysterious rubber compounds into your loop
3) the wire inside will corrode and fail, the hose will then collapse and be useless

Agree.

Every once and while you will see these and I have noticed GG still sells them but write on the website is specifically states manufacturer marks them as "Not for underwater use"

Why risk it.
