Kohler Aquifer Installation

The Kohler Aquifer under-sink filter connects to the existing cold water supply and plumbs to a dedicated Kohler faucet. The dedicated faucet installs through an existing hole in the sink deck (no additional drilling required in most cases -- standard kitchen sinks have a 4th hole for accessories). Filter housing mounts to the cabinet wall or door inside the sink cabinet. Installation time: 1--2 hours. Kohler provides installation instructions specific to each faucet finish -- finish-matched mounting hardware is included. The Kohler Aquifer system is designed for easy filter cartridge replacement: single-cartridge twist-off design takes under 2 minutes without tools.
