Traditional Gantry Suite. Includes Soap/Lotion Dispenser, Air Switch and single port Air Gap. Articulated spout lever with dish sprayer. 32 3/4" x 12 1/4" Air Gap is generally required in California. An Air gap keeps water from backing up into your dishwasher from the disposal. Proper plumbing techniques will also keep this from happening. California, however, does not give the option.
