The TOTO Gooseneck Vessel AC Powered 0.35 GPM Touchless Bathroom Faucet, 20 Second On-Demand Flow is ideal for high-traffic spaces, providing an elegant water conservation solution. The sensor is strategically positioned underneath the spout head to accurately sense the hands for touchless use. The 0.35 GPM 20 second on-demand faucet uses only 0.12 gallons per cycle and is CEC and CALGreen compliant. The on-demand system means that water flows only when needed and cannot be accidentally left running. When hands are present, the water will flow, and when hands are removed, the water will stop. SOFT FLOW technology gives a soft but enriching feel to the water with little to no splashing. Included items: spout, operating controller and mounting hardware included. Purchased separately: water supply line for G 1/2 inch connection. Requires 120V AC power supply.
