Just a reminder, to get a FULL load of water in the tank, let the water fill the tank for a few minutes, go in and turn on the pump. Then open all the faucets till all the air is out. For hot, start at the faucet closest to the water heater. Because of its 6 gallon volume it will take awhile for all the air to purge.
I usually drain mine after a trip, unless I am going back out in a week or so.
