The Affordable Macerator System! The SewerSolution provides a water powered high velocity jet nozzle using shear force to pulverize waste and toilet tissue and is strong enough to pump sewage up to 100 feet and 3 feet uphill. The patented system uses the "Venturi Principle" with as little as 15 psi. When the pumping is finished, the swivel jet nozzle cleans the whole system, both upstream (valve/pipe/tank) and downstream (drain hose). SS25 includes one 25' extension hose only.
