Kitchen and bathroom faucets were limited to a flow rate of 2.2 gpm (gallons per minute) at 60 psi, and residential shower heads were limited to a flowrate of 2.5 gpm at 80 psi. [ 3 ] In response to an increasing number of water shortages and increased water utility rates there has been recent legislation by many states leading the way in water ...
EPACT92 mandated new volume-based efficiency standards for toilets, showerheads and faucets as follows: toilets must be manufactured with a maximum flush volume of 1.6 gallons per flush (gpf); showerheads must be manufactured with a flow rate of 2.5 gallons per minute (gpm) at 80 pound-force per square inch (psi); and faucets must be ...

The relationship between gallons per minute (gpm) and fixture unit is not constant, but varies with the number of fixture units. For example, 1000 FU is equivalent to 220 US gallons per minute (0.014 m 3 /s) while 2000 FU represents only 330 US gallons per minute (0.021 m 3 /s), about 1.5 times the flow rate.
