The Delta Reverse Osmosis Beverage Faucet pairs perfectly with the Clarifi Tankless Under Sink 6-Stage Reverse Osmosis System and works with a wide range of filtration systems to conveniently provide purified drinking water in a variety of styles and finishes. Air gaps are integrated within the faucet for easy use with a reverse osmosis system. Delta Beverage Faucets are for cold water installation only and ideal for any reverse osmosis (RO), under the counter water filtration systems, or chillers but cannot be used with Instant Hot tanks. If installation does not require an air gap, the connection can simply be cut or coiled out of the way under the deck. Perfect for the pantry, butler's kitchen, or bar, but stylish enough to be featured next to your main faucet. You can install with confidence, knowing that Delta products are backed by our warranty and highly-trained, live customer support.
