Flushing is not automatic
Manufacturer instructions, water quality and tank age decide. An old Charlotte tank with a rusty drain valve can fail the moment you open it. We inspect before we flush.
Temperature
120°F is a common scald-reduction setpoint. Homes with mixing valves or special sanitizing needs should be set by a technician, not a random YouTube number.
What maintenance cannot do
It cannot save a tank-shell leak or a 15-year unit that is already rumbling and rusty. That is a replacement conversation.
