The 1.8 GPM Single Handle Touchless Pull Down Sprayer Kitchen Faucet in Brushed Nickel features a high-arch spout and two spray patterns: a steady stream for water filling and a powerful spray for rinsing. Touchless operation allows you to activate or stop the water flow with a simple hand motion near the sensor, and water automatically stops after 3 minutes if no motion is detected, helping to reduce water waste and prevent fingerprints and stains. The durable ceramic cartridge has passed multiple open-and-close tests, ensuring long-lasting performance. Its high-quality brushed finish resists rust, corrosion, and discoloration, making cleaning easier. Easy DIY installation is supported with pre-packaged accessories and instructions. The sensor works with 4 AA batteries (not included) and requires no external power source.
