You may choose to operate the faucet as you would any standard single-handle faucet by moving handle to the on and off positions. You may also tap it on and off with a deliberate touch, like that of playing the piano. If you have a Touch₂O_.xt™Technology faucet, the water flow is turned on by placing your hands within 4” of the faucet. To turn it off, you simply remove your hands from the 4” activation area.
