Its not suppose to be . The Yanks use a product called CPVC which is made for hot water . The standard here in OZ is only PVC . I was looked for CPVC alas no plumbing store carries it ( the ones I went to ) .
I believe a household favourite is made out of polyvinyl chloride, cling wrap, I wouldn't worry about plasticizers in the wort, the toxin we are making is far more damaging to our health than that.
I was eyeing off the fire sprinkler SS braided hose at a refurb I'm working at and thinking that would go great in a big mashtun. A lot of it just got turfed too.
Keeping a close eye on the SS glass door fridge in the cafeteria too...
This thread is bad I'm looking at my 100L camping esky and think "hmmm I didnt mind 3V" worse still I've got the spare pots to do it. This could well end in divorce .... again .... for the 3rd time!!
