Installation
DIY quick-connect fittings make installation fast and tool-free. The system mounts out of sight under your sink, connects to the cold water line via an Angle Stop Valve, and dispenses through the included solid brass faucet. A ½" hole is needed for the faucet stud — a cover plate is included to fit larger pre-drilled holes (e.g., vegetable sprayer holes). Installation Instructions
