The main idea is that the handwashing sink needs to establish a proper, steady stream before you start or restart the handwashing process. Running the faucet for enough time flushes out any air or stale water and ensures the stream is continuous and reliable, which is essential for effectively rinsing soap and hands and for avoiding a spluttering flow. Fifteen seconds is the amount of time that meets this requirement—the line is flushed and a stable stream is achieved. Shorter times, like five or ten seconds, may not clear the line or provide a consistent flow, while a longer run, such as twenty seconds, goes beyond what’s required. So, fifteen seconds is the appropriate minimum to ensure a proper stream before restarting.
