For the purpose of evaluating the performance of water saving fixture for dishwashing, water saving and energy conservation effects of styles of faucets with flow pattern and stop valves were examined by subject experiment. Subjects used a faucet with flow pattern options of shower flow or aerated flow, and with on/off control systems that included a foot-switch stop valve and a sensor stop valve. An experiment using a combination of the flow pattern and the on/off control function with the highest water-saving performances was also conducted. As a result of subject experiment, the water-saving rate of each device was as follows: shower-flow faucet, 29.1%(9.4L); aerated flow faucet, 3.7%(1.3L); sensor stop valve, 5.2%(1.7L); and foot-switch stop valve, 8.3%(2.6L). The combination of shower-flow faucet and foot-switch stop valve achieved water-saving rate of 44.0%(13.0L), confirming the additive effect.
