Replacement of 3058 Dometic Vacuflush toilet

As I've noted in previous threads, I've had a lot of problems with this unit.  I have been able to solve many of the problems (usually with Steve and Michele's help) but they continue to come up.  I have now been told that many of the parts are out of production.

Has anyone replaced this toilet with a newer model?  I've been told that the proper replacement would be a macerator model  because of the wide horizontal displacement of the toilet from the black tank.
Does anyone have any experience to share. 
I'm at the Motorcade at Sevierville, Tenn. if you are coming this way.
Thanks

Larry,

Do you have more details on why the suggestion of a macerator model?  There are still several Sealand VacuFlush models that make use of the same vacuum generator we have in our coaches (the pump does have an upgrade; see our 2011 efforts).  True, the "decorative" portion of our commodes is not a current model, but there are still several "above floor" portions that I think work with the rest of the mechanicals.

I think when I was looking on the Dometic website, it said that the replacement for the VacuFlush was the macerator model. I got parts (round seals and duckbills) from the authorized parts place in California with no problem. The guy I spoke to was a bit abrupt, but he knew immediately what I needed and got the stuff to me. There are about 5 "zones" to source parts from ... the guy in Florida was useless, so I am sorry if you need to call Environmental Marine in that SE area.  If you remember my post from back in February relating the "Saga of the Commode" ... and the fact that I now have a 4" $100 part made of STAINLESS STEEL, machined in the panhandle specifically to replace the $4.00 PLASTIC bit that goes from the little motor to the half-ball valve.  I have a LOVE /HATE relationship with this porcelain monster, to be sure.

To give a little more info, my current problem is the vac generator now is making a terrible pounding noise when flushed and seems to want to fly out the side of the coach.  My big fear is that something in the system is going to shear off leaving me toilet-less 2k from home.  I talked with the FT service guy and James  here at the Grandvention and neither were very positive about a successful repair from their experience. Nac has a replacement motor for the vac gen, but after reading Steve's story, I wonder if it is the motor. 
Prior to this I had the problem with  the false reading of a full black tank shutting down the system.  Steve's fix didn't work so I went to a boat repair place in Kemet Texas that services Sealand in boats.
They did a service but  systems for boats don't use a black tank shut off .No fix.  I called Domectic and a very rude guy in the service department told me that they had NEVER furnish a system to FT that had a black tank shut off BUT if I cut the #13 wire on the control board it might work,  The #13 wire comes off the board on the left below the  indicator lights. It WORKED!! 
What frustrates the heck out of me is that if I could have run the system at the boat repair place, they might have had some insight into the noise problem.  I don't have a lot of confidence in the toilet repair services at FT.  If you go to a boat place, they say there is a fault in the control board which the only replacement available cost $2000.00 and why would I want to keep the old piece of junk  They don't know how to change it out because they are boat guys
  Steve may be the only person in the world who truly  understands the system. He probably doesn't want to fly out and fix mine.
This why I'm thinking of tossing the whole system.

Michele,
I didn't answer your question.  The reason for a macerator is the toilet is two feet+ aft of the opening in the black tank (walk thru bath) and without the vacumn the stuff won't move so it needs to be liquefied,

With the toilet I just recommended:

http://www.thetford.com/Home/Products/PermanentToilets/AriaClassicwandwoWaterSaver/tabid/86/Default.aspx

you could fill the toilet with water after relief using the handy fill foot lever in the front, and before dump into tank, and flush with much more water than stuff.

We never put paper into the toilet, the lack of which would give added assurance a flush worked, but many do not like that approach.

I guess it helps to have changed diapers on 6 kids to be less sensitive to what comes out after it goes in...

As always, YMMV...

best, paul

Paul - the vacuflush is different than the Microphor you got rid of.  Vacuflush toilets are installed in coaches where the toilet is not directly over the black tank and some pumping is required.  A standard RV gravity toilet will not work in this application.

Larry - I understand the use, just wondered why they suggested going from a Vacuflush to a macerating toilet, but if the issue is your vacuum generator, I understand more.  If you aren't DIY on something like this, it's probably cost-advantageous to switch pumping technologies, plus you gain some storage space in the bay where the vacuum generator was.

Are you looking at something like the Techma Silence Plus?

I understand your point, Michelle.

But I've seen my toilet when it flushes a full bowl.

Unless the 2 ft of piping going over to the tank goes uphill I think a work-around is possible.

Of course, some folks don't want a work-around. That's fine. That's their choice.

But that doesn't mean it wouldn't work.

Moreover, I think a system that needs to pump sewage borders on a design error. One way or another, FOT could have used gravity instead of a pump. They chose not to. Why? How many guesses do you want?

best, paul

Thanks for the info.  My first wish would be to keep the toilet as it works well when it works.  The replacement toilet suggested by Domectic is the 8045, which is pretty expensive,  If someone has another idea, love to hear about it
