Does a Raritan Marine Elegance use less water than a Vacuflush?

Been lots of threads on replacing marine heads, but I am interested in only this subject from people who have swapped from the Vacuflush. The head seems to use more water than showers on our boat (and yes, we do take showers!).

I know the Raritan can be had with switchable fresh/sea water flush, but the seawater requires a pump and thru hull, and will stink a little more after awhile.

With the addition of the optional "Smart Flush" panel which provides 4 choices, the Marine Elegance can actually use less flush water than a VF actually needs to keep the hoses, pump and duckbills rinsed out enough to prevent problems with it (90% of problems are caused by using too little water).


In the 10 years since Raritan introduced the Elegance, I've yet to hear from--or about--anyone who's complained about a sea water odor problem from the remote intake pump.

Per Peggie, you need to flush more with a Vacuflush than most people do. I donít know which uses more water but I suspect that they are close if you actually use the proper amount if water in the Vacuflush. One advantage with the ME is that you have the option of using 1Ē discharge hose which will take less water to flush the crap to the holding tank than a 1 1/2Ē hose. I just got my new ME on Monday and will be installing it over the winter.

Our ME just arrived last week also But I think I will go with the 1.5" lines - just can't imagine, or bring myself to put a 1" drain line on a toilet

Sounds like not a dramatic difference.

If I swap, I'm thinking of using the sea water anchor washdown pump circuit for the sea water flush source. The pump is already needed, the thru hull already there. Only difference would be I'd need to leave it powered.

Any problems with the ME head connected to a fairly powerful washdown pump? The one currently in place is a wimpy Whale thing, I plan to replace it with something that can actually wash an anchor.

I'd install a pump that meets the water volume and pressure specs called for in the installation instructions Raritan Marine Elegance Owners Manual

And also keep in mind that you do need to install the SeaFresh system Raritan seafresh.pdf to be able to use both fresh and sea water, you can't just connect both water sources.

Remember that the ME is a macerating head so there wonít be any large chunks going into the discharge hose.

The specs only list minimum volume and pressure, which any washdown pump will do. The question is will it stand 60 psi or even more, that a good washdown pump will put out?

Now Iím curious.

For those who have removed a VF head and replaced with a Marine Elegance...

Thinking of the physical side of the installation, and the deck fittings that the VF uses, how did the installation work out?

* Were you able to down discharge like the VF?
* 1.5Ē hose like the VF?
* Capable of pumping a bit upward like the VF?
* Was the original VF deck hole completely covered, or did you need to fabricate a deck plate to complete the installation?


Iím pretty happy right now with my VF heads, but one of them has the vacuum generator in a not so easy to access spot, making it a candidate for possible replacement.

Both of my heads go to a 1.5Ē wye fitting and then to the holding tank, no valves in the way.

Have you looked at what comes out of the macerator? It is basically a slurry that I donít see as a problem plugging up the hose. With the smaller hose you will be able to completely clear the poop to the holding tank with less water and therefore I think it will keep the hose cleaner since you wonít be as leery about using a bit more water to completely flush the hose.

Yes it has a down discharge. I got an adapter so I can back discharge.
Yes it can use either 1” or 1 1/2” discharge hose.
Yes it can pump uphill.
Don’t know about the hole coverage since I have not replaced a Vacuflush.

I did make a 3/4” plywood base for mine since there are multiple holes in the fiberglass from who knows what over its 32 years.

That's a question for Raritan. Give 'em a call at 800-352-5630. A real live person actually answers the phone in tech support.

A good person to contact at Raritan tech support is Greg Morales. Very knowledgeable about their toilets and pleasant to deal with. I spoke and emailed with Greg on my original Crown toilet installations and am doing so presently on converting them to freshwater SeaEra's.

I had a VacuFlush system on boat for the last year (the boat was new to me a year ago) and switched to Raritan Marine Elegance about 2 months ago. I had two heads, and switched both heads at the same time.

With the VacuFlush system, I had smells almost constantly, mainly due to the tiny size of my tank, and filling it up more often than I'd like. It used a lot of water, IF the crew used it right. That is part of the problem - you have to train them that for solids, they need to give it 7-10 seconds of water to ensure things get where they are supposed to go, and not gum up the works. After a year of use, things were starting to show issues which would have required more maintenance than I would have wanted.

With the Raritan system, I am 100% using less water, as I can go almost 3x as long without pumping out. Not only that, it is dead simple for my crew to use - I even put little colored stickers on the smart toilet control panel buttons that they should use the most often, and matched the colors to... well the input if you know what I mean.

Peggie was instrumental in providing data to help me make this decision.

I also installed a similar system on my previous boat (a sailboat) although I think it was the SeaEra model, but it still used the same control panel. Had it for 4 years with little or no maintenance, and a perfect track record.

LOL! Now THAT is a great example of the depth of actual experience (dispensed with a dose of good humor) that makes reading some threads so worthwhile.
