Can not imagine plastic water pipe being a problem, think of the consequences.
My boat has a SS tank, and all copper pipes. Copper is good for keeping water clean from bacteria and fungus.
These copper pipes are original to this boat, from 1970. They are mechanically joined, using ferrules and nuts, not soldered.
