vac u flush
Can someone explain the difference between the vac u flush system found on some motorhomes, compared to whats found on travel trailers or 5vers?

There are 2 types of remote Toilets
1. TRUE Vac u Flush, uses a remote vac pump to "pull" the debris from the toilet thru the Vac Pump small reservoir and then forces the waste to the remote Black tank. This uses very little water, usually about a pint per flush.
2. The 2nd is a Macerator style pump system, that uses plain force from the pump in the toilet to get the waste to the Black tank. This is the most common remote RV toilet used
3. The Vac u flush I have only seen in Fleetwood Motorhome products, but I know others use them. The disadvantage to the Vac u Flush is, the down pipe from the toilet to the Vac pump is only 1 inch in diameter. Then it has a larger hose from the Vac pump to the Tank. I have worked on just 1 and it was because the down hose from the toilet was clogged. REAL PIA to work on because you have a few qts of sewage water to deal with. Then they usually install the Vac pump in a inaccessable area under the main floor.
4. I would opt for the Macerator toilet rather than the Vac u Flush.
