Has anyone used one of these vacflush ? Any raves? I have been looking after a 57 foot Riv and she has 3 of these in her cabin.....seems like a good unit with a huge dump capacity!

in fact i feel a huge dump coming on as i speak !!! 
Your slightly weird SandS !
i have been maintaining these loos weekly for 6months although they only get used 3 times a year I like the concept!
Has a approx 150mm plastic ball type to hold the water and waste and when you hit the lever the ball opens and the entire waste dumps into another compartment obviously from there it gets macerated and sent to the tank or the ocean.
im sick of the TMC electric 50mm diameter that always seems to block when others use it. Its like you need a instructional brief for all that come aboard!
Seems theres a left/right/below/back attachment that may require some thought.

i,m glad you think i,m only slightly wierd !!!
Yep, got one but a different model. My toilet looks very much like a domestic toilet (an not a small cake mixing bowl on a stick) and the tank is curved to fit against the hull. The complete setup is not cheap but very reliable. I have a watermaker so I run freshwater through it. The only thing is doesn't like is DRY toilet paper. But it can easily pull half a bowl of wet toilet paper (plus some other unmentionable stuff) from the bow. The narrowest part of the system is directly below the valve (bottom of the bowl) and can be poked with a long screw driver if someone decides to try putting dry paper down it. Very happy with mine.
If you do get one, my only advice would be to find toilet hose with a smoother interior and heat it to make it soft before tightening the hose clamps. The system needs to create a vacuum and hold it prior to flushing and any sort of leak will be counterproductive.

I would imagine the guys will be a the Sanctuary Cove Boat show this weekend if you are in the area.
We are all a bit weird I think! Some nights after work If it's not to cold outside I let Trim into the warmth and we play hide under the tea towel. It's a funny game,

Seems expensive. ...but definitely depends on the size and quality of the boat.
A simple composting camping toilet works for us
I just try and keep everything as simple as possible.
Can't get parts even if I could afford them for anything fancy

This ones for you ChopesBro 
ChopesBro if you want really simple just hang it all out over the transom, with following waves you even get a free wash up 
Reminds me of the time my first officer decided to unblock the loo on my old Mottle 33. It was necessary to crawl into a narrow space to unbolt the hoses. It was a particularly hot summer day and the visitors had all pumped the loo handle hard to try and unblock it. Its surprising how much pressure can build up in those hoses as my first officer found out when the first hose clamp came undone and the hose flew off under pressure covering him in .... shell we say stuff. Its astounding how fast someone can crawl backwards out of a narrow tunnel and dive overboard screaming "yuk.......!!!!!!

Oh That also reminds me Not to offer myself as your first officer
i had those toilets on my previous boat. 2 toilets going into two very large separate vacuum tanks. great in that they use very little water so for 6 guys spending 10 days aboard at the abrolhos only emptied the tanks once. the seals at the base connecting the bowl to the base unit leak a little if there's a large user. if the vacuums working properly there is no smell. They absolutely hate anything other than 1 or 2 ply biodegradable toilet paper. If they do get blocked they are a nightmare to un clog. Expensive to repair and maintain compared to macerators. I like them but on my new boat im in the process of replacing the old macerator toilets with blue wave hydro vacuum toilets. the toilets are one piece so no leaky seals and while a little more expensive to buy than the sealand vacuu flushes, work out a lot cheaper when you factor in the sea land cost of vacuum pumps and holding tanks (starting at around $ 2700 for their cheapest unit.) the blue waves work out to be roughly 30 to 40 percent cheaper due to the pumps being built into the toilets. You just use an off the shelf sullage tank.
