Another rookie water system question

[dennis 221]

When draining system after sanitizing would it not be easier to after tank empty connect my hose to camper to flush out heater an water pump?

I’m not sure city water goes through the pump, but it is a way to flush the heater. A tank wand helps, too.

Since you said rookie, I’ll remind you to use a proper pressure regulator when connecting city water.
