I'm a 3rd generation plmbr. in northern va. We have never installed the toilet but they used have the pump system, wich we connected to a big jacuzzi type tub on the far side of basment, customer looking for a cheaper way insted of bustin concrete all the way across basment, that worked fine. Saw a demo. at the supply house, not highly impressed. A few plmbr. friends installed toilet, few months later went back and busted up concrete, there customers were not impressed. The supply house we use, J&H Atchisons in Falls Church Va., doesnt carry it anymore. I think! Hope that helps. Good Luck!!!!
