Web alarm clock for 4:46 p.m.
Before handing over the house duties, you set a 4:46 pm alarm so the next person remembers to switch on the water pump after the scheduled brownout. That gives them a clear cue before 5:00 pm, when other routines may begin competing for attention. Tell them where the pump switch is and whether the power has already returned, so the reminder leads to the right action.
Because the pump restart depends on hearing the alert, check the phone’s sound setting while you explain the handover. Silent or vibrate mode can make a visible alarm easy to miss amid electric fans, traffic, or conversation. Keep the browser alarm open and the phone awake: if either is shut down, the pump reminder will not sound. A separate phone alarm is a sensible backup when nobody will be watching the screen.
As afternoon activity continues around 4:46 pm, let everyone at home know that the pump may start shortly after electricity returns. Ask someone to check that taps are closed and that no one is using an area where sudden water flow could surprise them. A brief spoken notice also prevents two people from reaching for the same switch during the changeover.
