Managers typically specify lavatory faucets for three broad applications.
The first category is hand washing in public restrooms. Most codes require flow rates of 0.5 gallons per minute (gpm), a minimum to earn LEED credits.
The second category is private fixtures used for moderate hand washing and light bathing — face washing, shaving, or teeth brushing. Codes usually refer to these facilities as private lavatories. Managers typically specify fixtures that use 1.8 gpm or less for these applications.
The third category is private fixtures used for heavy hand washing, such as medical, culinary, and maintenance applications. These applications require more water, so managers can specify fixtures that use 1.8-2.2 gpm. Most codes restrict these fixtures to less than 2.2 gpm.
