Ummmmm NSF PVC Is definitely not toxic !!! Maybe you should do some research because that's what hot water goes through and I've never been poisoned off my morning coffee
Uhm, your original post did not say that you were using NSF... Either way, I'd still not use NSF either.
Currently, polyvinyl chloride (PVC) and chlorinated PVC (CPVC) plastic pipes and components are used for conveying potable water. In the polymerization process, some of the vinyl chloride monomers are retained in the plastic pipe matrix (PVC or CPVC) as a residue and may be released into the air or water (WHO, 2004; Richardson and Edwards, 2009). In early field investigation (Dressman and McFarren, 197
and experimental studies (Ando and Sayato, 1984; Banzer, 1979) demonstrated the ability of residual vinyl chloride to migrate from water distribution PVC pipes into the water flowing through them. The extent of leaching is determined by the vinyl chloride concentrations in the pipe material. In the field study, the highest vinyl chloride concentrations (1.4 µg/L) consistently occurred in water from new pipes, whereas the lowest level (0.03 µg/L) was found in the oldest (9 years) distribution system (Dressman and McFarren, 197
. The amount of vinyl chloride migrating from rigid PVC pipes into drinking water was found to be directly proportional to the residual level of vinyl chloride in the pipe itself. Older PVC pipes may contain vinyl chloride in concentrations up to 600 mg/kg, and have been shown to leach vinyl chloride into drinking water (Beardsley and Adams, 2003).
PVC is generally used for cold water applications for distribution system and premise plumbing pipes and components (i.e., fittings). The National Plumbing Code of Canada (NPC) allows the use of PVC only for cold water plumbing applications (NRCC, 2010). CPVC has higher heat resistance and greater mechanical stability from the chlorination process. Under the NPC, CPVC is permitted for use in both hot and cold water applications (NRCC, 2010). It is also important to note that the NPC has required that all plastic pipe meet the Canadian Standards Association's (CSA) standard for plastic pipes (CSA, 2009). The CSA standard was revised in 1990 to include a leaching test for vinyl chloride into drinking water. The CSA B137 series of standards for thermoplastic pressure piping currently requires that PVC and CPVC pipes and components (e.g. tubing and fittings), used for drinking water applications, comply with the requirements of NSF/ANSI Standard 61 (CSA, 2009). This standard limits the leaching of vinyl chloride (monomer) to 0.2 µg/L into drinking water. Pipes and components meeting NSF/ANSI Standard 61 would be expected to leach very low concentrations of vinyl chloride into drinking water.
So, as you can see, NSF is not COMPLETELY safe either. They are expected to leach "very low concentrations", but, it's not NIL.
I've also seen other people who have made tents using PVC, some companies also use PVC as the main reflective material in their tents.
Then people wonder why their plants are dying from toxic shock as Vinyl Chloride is leached into the atmosphere of their tent.
On top of that, I run a 1000w with the smallest Hydrofarm hood they have, there is NO way that PVC frame will hold even the smallest hood. The metal frame that is in my tent BARELY holds a 1000w and that smallest Hydrofarm hood, and without a hood, the heat is directly hitting that PVC and without any type of water cooling inside of it, it is and WILL leach contaminated NSF-PVC into the tent. Regardless of what YOU think YOU can handle as far as drinking it in your coffee.
137 = 3 points shy of Genius , hence the reason I finished school by 16 & had 2 college degrees by 19
