Hands-free faucet can have reduced flow rate
From: Hastings Tile & Bath
The VOLA Electronic Hands-Free Faucet from Hastings Tile & Bath makes all electronic boxes water-resistant, including its connections which are made with watertight seals. Part of the point system for LEED certificates, the wall-mount faucet’s standard flow rate is 1.3 gpm but can be reduced to 0.5 gpm, and the time can be set from 20 seconds to 10 or 3 seconds. Each unit has a built-in hygienic rinse to ensure fresh water moves in the lines and traps are bacteria-free. Additionally, the faucet includes a built-in data port in the box, so one could upload data to see how much water has been used.
