The All-New Dometic MF410: Next-Generation Replacement for the MasterFlush 7640
The Dometic MasterFlush MF410 is the new version of the 7640, the pedal-operated macerating RV toilet. With the 7640 out of production, the MF410 is the current choice for owners who want to replace a 7640 and for RVers who want a macerating toilet that flushes by foot pedal like a standard RV toilet. It also has a redesigned bowl that conserves space.
A macerator pump grinds waste and sends it to your holding tank through discharge plumbing. That lets you install the toilet away from the tank instead of directly above it, which is useful for a second bathroom in a motorhome, fifth wheel, or towable. Because the toilet isn’t mounted directly over the waste tank, the setup also helps keep tank odors out of the bathroom.
Key Features:
- Pedal-operated macerating toilet, the MasterFlush design that replaces the 7640
- Redesigned bowl for a more space-saving footprint
- Macerator pump technology for flexible installation away from the holding tank
- Foot-pedal flush operation, familiar to RVers used to standard RV toilets
Replaces:
- Dometic MasterFlush 7640 (304764001 / 304764002)
Will the MF410 Fit Where My 7640 Was?
The MF410 is designed as the successor to the 7640, but it has a different bowl. Before ordering, compare the MF410’s footprint, rough-in, and mounting dimensions against your existing 7640 and your bathroom layout. If you’re not sure, contact us with your 7640 model number and measurements and we’ll help confirm fitment.
Frequently Asked Questions
Is the MF410 the replacement for the 7640?
Yes. The 7640 is discontinued, and the MF410 is Dometic’s new pedal-operated macerator toilet in that line. Parts for existing 7640 toilets are still available through Dometic’s distribution channel.
Is this the same as the Dometic 410 gravity-flush toilet?
No. The Dometic 410 (Complete series) is a gravity-flush toilet in the 400 Series. The MasterFlush MF410 is a pedal-operated macerating toilet that grinds waste and pumps it to the holding tank. Check the “MF” in the model name before ordering.
What’s the advantage of a macerating toilet?
Waste is ground and pumped to the holding tank, so the toilet doesn’t have to sit directly over the tank. That’s useful for a second bathroom or any layout where a gravity toilet won’t work, and it helps keep tank odors out of the living space.
Why is this a special order item?
It’s a new product that Dometic supplies directly on order instead of stocking in regular retail inventory, so we order it for your purchase.
