Question for Macerator pump users

[Uncle Dougie]

I have a Valtera SewerSolutions to use when I return home with a tank that has not been emptied (not very often). I dump through an outside sewer cleanout that is about 18" above and 20' away from my tank valves, I connect with 1" pvc pipe. It works great. It does take quite a while to clean the tanks but I'm a little picky about flushing my tanks. I would not recommend the sewersolution for everyday use but for me it works.
