Oh no, then definitely don't do it out of the tap. I think you could try to get crafty and creative to rig a way to do it with the treated water you can use. Certainly keep doing the warm baths like the Dr. said.
I have a very deep well and the water has no impurities whatsoever, no metal imbalances, and the ph is neutral. Has a little sulfur but I have a large, inline filter system that catches it before it gets into the plumbing.
