The First Pedal-operated Macerator Toilet Delivers Power and Comfort Step RV owners up to a powerful, comfortable macerator toilet without the premium price of an all-ceramic toilet. The MasterFlush 7640 RV toilet is the first pedal-operated macerating toilet in the recreation vehicle industry. Fitting in the same space as older RV toilets, the MF 7640 toilet offers a user-friendly, powerful performance upgrade from typical gravity-flush toilets. It easily replaces many gravity-flush toilets, or makes a great “second†toilet without being located directly above the waste tank.With a dual-stage impeller/macerator pump, this toilet pulverizes effluent and toilet paper with as little as 0.17 gal./0.64 l of water. Because its discharge plumbing completely isolates the holding tank, the MF 7640 toilet eliminates the possibility of any waste tank odors entering a bathroom. Key benefits Powerful macerator flush
