Product Description Perfect for modern and traditional kitchen settings alike, the Watts Premier Standard Auxiliary Faucet combines aesthetic appeal with practical functionality. Designed to work seamlessly with reverse osmosis under sink water filtration systems, this faucet offers both style and functionality while complying with all US plumbing codes and NSF low lead requirements. Its elegant chrome finish not only adds a touch of sophistication but also provides durability and resistance to tarnishing, ensuring a long-lasting, beautiful appearance. This faucet includes a standard 1/4" supply tubing connection, offering straightforward installation and making it easy to integrate into your existing setup without hassle. The Touch N' Flow spring-loaded handle allows for convenient one-touch water dispensing, adding to the faucet's user-friendly design. Unlike non-air gap faucets, this air gap faucet requires a drain connection in order to prevent backflow; by creating a physical break in the flow of water between the RO system and the drain, it ensures that wastewater cannot siphon back into the clean water supply, protecting your water from unwanted materials. The faucet's non-monitored design encourages proactive water quality management by requiring users to manually track their filter replacement schedules. This ensures that you can maintain consistently pure and fresh water tailored to your specific needs. By staying on top of filter changes, you guarantee that your water filtration system continues to operate at peak efficiency, delivering clean and great-tasting water at all times.
