I live in a slab home. Our refrigerator is next to the closet that houses our washer and dryer. The kitchen sink is on the opposite wall. Would it be possible to hook up a water line from the line going to the washing machine for the ice maker? Would that be unsanitary? We don't really have a water filtration system on our line, just a Pur filter on our faucet. I would greatly appreciate any advice. Thanks!
