I also use the Macerator like Orv does, I have a incline on my property at least 5 feet above the street and a 75 foot run to the clean out. It has saved the day quite a few times for me, the only thing I have against them "RV Sani-Con" is they sold out to Thetford I have not had to have any parts replaced yet, so I dont know how Thetford will react to me asking for parts for the original Macerator if I ever need them. it is costly compaired to the others on the market, but I have never had a problem with it. the Macerator works just like there add says.
