After I studied this little muncherator, and what I have to do to get the tanks emptied I noticed that if I am pumping out and up a hill and when I’m empty, I have to turn the pump off according to the instructions “do not run dry”. So once the pump is off, all that waist that is in the hose, now according to Newtins Law of Gravity all will flow down the hill to the pump and back into the trailer conector, so I see a problem and I think I might have a fix for it, and I will share it with you it can be used on any waist pump if wanted.

You can use the ball valve to turn off the flow of water after the pump is off, making a small amount of water flow backword the the hose can be removed and taken to the top of the run and then open the ball valve to let it flow into the sewer line. And shown without the valve for regular use at campground. Tag it.
