Not sure if you do or don't have a screen filter at the pump, but on our SOB trailer a few years ago, we lost water flow from the pump. checked everything I could think of that would stop water flow, so changed the pump. Not knowing any better, I swapped the filter to the new pump. Guess what? No water with the new one either. Finally figured out how to take filter apart, cleaned some green slime from the screen, and we were back in business. I'll bet, even if you sanitized you tank and plumbing, you might have a clogged pump screen.
