“#4 is OK, as are #2 and #5. … “Vinyl is out, and that includes #3 PVC (polyvinyl chloride) plastics. Completely. Totally. And I do have a little rhyme for this one: “No vinyl. That’s final.” (Or, if you prefer, ‘No PVC for me’.)”
Read more on vinyl / PVCs at Grist.org. And read up on GARDEN HOSES at Grist, where they frown on the prevalent vinyl hoses and recommend only rubber hoses, which are much sturdier and which you can buy through Sears, Gilmour, or your favorite Internet sex toy dealer. (Me bad.)
OPEN THREAD. … Your turn to be bad.
