I don't see why not. Most of them are built such that the water only touches plastic, although this is something that would need to be checked. Obviously they are designed to not harm fish that have to live in the water. I don't think humans are less tolerant of what they drink. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
