PVC: poisonous?

i can't see how that could be accurate. we've been using it for years with no ill effects. pvc is inert.
the founder of that organization is a housewife, not that i have anything against housewives, but she has no credentials except standing up for herself because her house was built on top of a toxic waste dump. they have one doctor on staff.
i'd like to see alot more influential folks standing with these accusations before i get worried.

That's weird, I was just reading about this today because I think I was told last year that machining pvc is bad. One and two cuts is one thing but when you actually machine it from flat stock a cloud starts to form. I thought it was pvc but maybe I'm wrong, so I was looking for more info.

...then again, that bottle of Poland Spring water (or any of the others..) on your desk is also a danger to you. If you froze it (not suggested) or left it in your car (also not suggested) and it got hot...well that has caused the nasties in the plastic to leach into the water you are enjoying...
As far as I know, anything made of a plastic material has some petroleum product in it - so where does that leave us? We can't very well use metal piping on our SW tanks
Is there another option?

yes PVC is used for cold water supply lines. For hot water, CPVC or copper is typically used.
I'd only be worried if your hot water piping after the water heater is PVC.
PVC is safe if used properly...

First off, there're different kinds of PVC. The PVC that we use in our tanks -- the hard, rigid stuff -- is highly stable. So long as you don't burn it or heat it excessively, it's safe. (You basically just need to take care if you're using high-speed machine tools on it, or around, say, MH fixtures.)
Soft PVC, however, is a different matter. The material contains plasticizers which tend to be volatile and leach out of the plastic. This is the stuff that everyone's freaking out about in baby toys and squeeze bottles and such.

Soft PVC = flexible pvc?
AFAIK, so long as you're doing it right -- using a diffuse method like heating under sand or something that ensures you don't overheat any part of the pipe, it's safe. If it starts yellowing or burning, you're getting it far too hot and that may be a problem. So long as you're not chemically changing the material, you should be OK. Mind you, I'm no expert on it.
Yep. Anything that's PVC and is softer than your bog-standard PVC pipe.
Well i guess i have some serious researching to do because i have actually burnt the damn thing in the past. The PVC pipe should have a warning lable on it...Thanks to the person how post the thread we need members like you.AFAIK, so long as you're doing it right -- using a diffuse method like heating under sand or something that ensures you don't overheat any part of the pipe, it's safe.
