Hi Folks, is it possible to do this conversion? If so, what is needed? Seems the intake hose would be the same size, but the outlet to the Jabsco is likely 3/4" due it is macerating from the toilet whereas the Groco is passing un-macerated waste from the toilet to the tank via a larger hose diameter. Forget the size....
Thinking would just need to use a reducing adapter to the Jabsco toilet and install the electric flush control?
 
An adapter should work, but have you thought about replacing the entire outlet hose, and the fitting on the tank? Those hoses don’t last forever, so now might be a good time to do it?
 
Replacing the hose is something I will look into once I can get my boat back from the canvas shop. Just wondering if anyone has done this and also if this is a smart move? Is the Jabsco quiet flush E2 reliable? I have to rebuild my HF pump every couple of years, so not finding it very reliable at this point.
 
With pressure from my all female crew (wife and two daughters) I reluctantly switched from a Jabsco to Raritan Elegance this summer. The conversion was straight forward and at the end I have no regrets.

I heard good things about the Jabsco Quiet flush. If you don't already use on-board fresh water (from potable water tank), you will be pleasantly surprised. River/lake/sea water has organic material which have their own source of odors.

It shouldn't be too difficult, good luck!
 
I replaced my old vacuflush two years ago, went with the Rartian Marine Elegance, which seemed to be the most popular. Haven’t had to do any maintenance on it yet.

The install was easy, biggest surprise was that I had to run heavy ( expensive) wire, 6 awg I believe. spent over $100 on wire.

I am not a big fan of vacuflush, they seem cool but way too many moving parts. Plus I don't think they are all that quiet.
 
It was sort of cool the way it sounded like an airplane toilet when flushed - but it never really worked. way too complicated, and parts were insanely expensive. I don’t know why they have such a huge fan base, I was glad to drag them to the dumpster.
 
Hey folks, rethinking my decision on this toilet mentioned now thinking based on high reviews of the Raritan PH Superflush Manual. Looks to be a fairly simple swap from my Groco HF. I just did a rebuild kit on the Groco HF and it still is struggling to work. These parts are getting expensive and a PITA to keep working on it for what little it gets used.
The only question I have on the Raritan is the flush pump handle. Seems it is a bit in the way when sitting for a bigger person? Anyone know or experience if this handle is truely in the way? This would be for the compact series size toilet.
 
Well, I jumped the gun here. Unable to use the Raritan as it is too wide.
 
Ok, sorry folks. I put forth some more effort as something didn't make sense on the measurements. I compared the Groco HF against the Raritan and they were about 1/2" difference. I used a free tape measure given to me by Marine Fisheries and didn't realize it has over 1" from the end before it begins the measurement....Geez. Ok, so re-measured and seems the Raritan is back on the map. So back to my original question from above about if the pump handle would get in the way when sitting? It will however be right against the wall when installed, so maybe not a big deal?
 
Just my personal opinion, but I am not at all a fan of manual pumps. They work fine, and if I was only one using it I would be ok. but it’s too much of a hassle explaining how to use it to every guest you have on board, kids, etc. Unless I had a sailboat with limited electrical capacity, or spent tons of time at anchor and needed to preserve every amp hour, I would go electric. Yes, more expensive. But probably worth it, in my opinion.

We had a manual flush on our Luhrs and I agree with you comments. Not only the hassle of guests onboard, the maintenance was almost never ending. Especially if the boat sat unused for any length of time.
