VacuFlush-compatible toilets? (split from Re: Microphor to 320)

 Looks like the 320 is only for direct gravity drop straight into the black tank?

For those of us with the vacuflush systems, what toilets are interchangeable?

Dan, my coach doesn't have a direct drop from the commode.  There is an offset and most have that.  No issues with the Dometic 320 commode.
Now, with your vacuflush, not real familiar with that system.  Is that a pump type where it is pumped from the commode to a long pipe to the tank?

Yes, the vacuflush pump is in the basement, and pumps (actually vacums) waste from the toilet, through the pump, then into the offset black tank.  The discharge from the toilet is at the rear, not under the toilet,  and approx is 1.5" discharge tube.


I will start a new thread soon about possibly converting to a macerator toilet, which would allow for removal of the basement mounted vacuflush pump.

Correct.

VacuFlush is very common in the marine world.  A quick search for Sealand VacuFlush brings up a couple of good resources:

You basically need something compatible with that specific vacuum generator and the control.  That's a VG2 vacuum generator which looks like it's no longer made.  You might be able to swap to a VG4, but you'd have to check size/space.  VG3 is designed for small spaces, so that could also be an option.

For a change of direction on Vacuflush system and toilet (changing to macerator toilet), a new topic is at this link:  Macerator toilet system to replace entire vacuflush system
