I have a customer that wants a T&S drinking water dispenser installed behind the ice bin. Is there anything in the codes (plumbing or health) that would require a drip tray to prevent any possible water from dripping into the ice bin? Besides that, there are two outlets(220 and 110) on the wall behind and within 2 ft of where I would be locating the dispenser. Is this allowed as long as they are GFI protected? Thanks.
