When I was stuck in the middle of the yard for over a week when I had my axil problems, a macerator cam in real handy. I could have been the original cuz it burnt out after running it several minutes. I now have a shiney brand new one with led lights on it. Looks neat.
With a macerator, you can do one of the things that plumbers say cannot happen. They say poop doesn't run up hill, but it does woth one of these fellows.
