The pump was running because my valve to the tank was open. It wasn't a closed system. Once I found the UNMARKED valve (knob) to cut off water access to filling my tank, the pump turned off. Now the water works the way it is supposed to. I figured out the procedure and steps to getting running water to my RV, from the tank or from city water. Woohoo!!! I feel like a nerd getting so excited when I figure this stuff out (with some help from you guys and some neighbors).
