The Waterstone RO Air Gaps are not only to prevent backflow to your reverse osmosis filtration systems, but will look good in the process. Decorative design matches traditional Filtration Faucets and accessories. The RO unit provides a siphon “air gap” for the reverse osmosis system to drain properly and not let brine water or dirt back into the system. Solid brass or stainless steel construction and available in 31 finishes.
