Sanitizing the water system

I drained the treated water and refilled the freshwater tank. I removed the plug-rod from the W.H. and got doused because I hadn't relieved the pressure first. Then I opened the relief valve and the water ran out of the W.H. tank while I changed clothes. So I turned the pump on and tried to run water from the faucets in the bathroom. Very little water came out and the pump wouldn't stop running. So I figured I must have blown a water line and I went out to see where it was running down from and that's when I realized that I hadn't closed the W.H. relief valve. So all is good now.
