We use the tank to increase the water pressure when needed i.e showers and dishes.
The quickest way to drain the tank is purging the water through the pump. When draining I noramlly just turn the pump on by using the switch by the exterior shower, and turning on the cold water faucet on the shower.
We do not use the water for drinking but we do sanitize with an ounce of bleach per full tank a few times a year.
