Well, back to my outdoor shower ...
The nearby hot tub is the SoftTub variety, which run off parasitic heat from the pump (for the jets) and therefore requires several DAYS to come up to temperature. Thus, since I've installed both a cold and a hot water hose bib there for the outdoor shower, I'd like to do the occasional topping up of the hot tub with hot water. So I bought a short garden hose to dedicate to this purpose semi-permanently connected to the hot hosebib via a Y-connector.
However, the fine print on the hose (a fairly cheap Husky brand from Home Despot) says "do not use for hot water". So, what will happen if I do ? Is there a type of hose that
is suitable for hot water ? Should I just use PEX ?
