Why would you use vinyl or pvc tubing and gutters? Have you ever seen the movie, Blue Vinyl? That stuff is toxic. Wouldn't it contaminate the water? Not to mention the fossil fuel that went into producing it. —The preceding unsigned comment was added by Barkway, 20 June 2012
- Good question - just glancing at the page, I don't think they addressed this.
- My understanding is that unplasticized PVC is extremely good for handling water and maintains the purity of the water better than other piping materials - but it's also very brittle. The problem is with the plasticizers used in PVC for consumer products. I'm not sure about the tubing and gutters - probably the gutters have some plasticizer in them, but not a lot.
- Another thought: if the water flows over the plastic briefly rather than being stored in the plastic, that should mean much, much less contamination. Personally I wouldn't be worried about it, as long as a first-flush system is used and the storage container is either non-plastic or a hard, preferably unplasticized polymer. --Chriswaterguy 03:26, 21 June 2012 (PDT)
I can't figure out how to reply to your message on your user page so I hope you see this. Thanks for reply. —The preceding unsigned comment was added by Barkway, 23 June 2012
- No problem. For reference, if you look at someone's user page, there'll be tabs at the top saying "User page" and "Discussion" - go to discussion, and edit and leave a message at the bottom. We'll do something to make that clearer. No need this time anyway - cheers. --Chriswaterguy 22:00, 22 June 2012 (PDT)
