Does anyone know if "commerical" showerheads such as the Whitehall Ligature Resistant Wall Shower (Model WH418-CSH), which has a flowrate of 1.5 gpm, and teh Whitehall Ligature Resistant ADA & CBC Compliant Wall Shower with Hand Held Shower (Model WH418ADA-WHCHS) have to be WaterSense labeled? Are they even eligible to be WaterSense labeled? They are not "typical" commerical showerheads, but rather used in institutions.
