I figured out today that I could recirculate rinse water through my duotight beer line with a submersible pump. As long as you have a pump that accepts 1/2” thread the 9.5 mm evabarrier line fits over the floating dip tube after a soak in hot water. Then I just connected my liquid out disconnect to the post on top of my fermonster lid. I suspect this would work for cleaning the line too but I don’t trust the chemical touching the pump.
