  • Swirl-jet flush action assures powerful, more thorough rinsing of entire bowl
  • Most comfortable RV toilet height
  • Easy, direct replacement for gravity flush RV toilets – mounts to existing floor flange
  • Allows toilet to be installed away from holding tank; not locked into directly-over-waste-tank installation
  • Macerated effluent is more easily, more thoroughly discharged from tank
  • Great for towables or motorhomes with 2 bathrooms
  • Uses proven MasterFlush macerator pump technology
  • Push pedal slightly to add water; eliminates need for hand sprayer
  • “Full” tank shutdown prevents overfilling waste tank
  • Self-contained unit – no additional flush switch to install

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.

* Based on standard 10 in./25.4 cm toilet rough-in dimension.
