Q: I'm trying to be all eco-friendly and add a shower volume control knob onto my shower head to use less water. However, the directions for installing it call for Teflon tape. I know that tape is used commonly in plumbing, but Teflon is made by DuPont which has a less-than-stellar environmental record. Is there an alternative that doesn't contain toxic chemicals? What did plumbers do before Teflon tape?
