Every couple of years?
Is it an incinerator toilet with some sort of storage for the ash?
Incinerator toilets look interesting but they do have quite high 240v power requirements for the heating cycle .

I am definitely not 'having a laugh'. I have no problems AT ALL with properly managed composting toilets. I have huge problems with composting toilets on boats, and insurmountable problems with composting toilets on Continuously Cruising boats. Frankly they are unworkable in all regards, the ONLY acceptable way of achieving any form of workable, legal system is to throw your shite down an elsan as you fill the boxes/containers. Can someone please tell me what is the point/advantage of that? I agree with you but I note you seem to be exceedingly sensitive about this particular subject and prone to "going on about it" Are you perhaps flogging a dead horse ? Do you have particular issues around disposal of toilet waste on inland waterways vessels? Have you seen a shrink about it I certainly do go on about it because it is a hopeless, unworkable system. I want to hear how a CCer utilising such a biowaste-management system can possibly make such a system work, both literally and legally. The only correct answer is that it impossible.

Can someone please tell me what is the point/advantage of that? It all depends on the type of composting toilet fitted. The only one I know anything about is on a barge on the Medway and it is the thermal composting type where the resultant material is composted internally and what you remove can be put straight on a garden. The owner lives alone and the unit only apparently needs emptying every couple of years. I would like to know more of this as it sounds vaguely workable. I suspect the answer may lay in the fact that it's a barge and may have enough room to adequately compost ass-fruit before disposal.

Thanks Peter. But you have a mooring of course. If you were off cruising, you couldn't use your friends compost, so what then. I know tomsk is 'having a laugh' but I am genuinely interested. I know composting works, it's the 'on a boat bit' I'm sceptical about. Rog I have in the past just buried it went past a year later to see very green grass growing high made me smile. As for throwing it raw on a friends composting bin by the time it hits the bottom its gone so clearly the system works. If Tomsk want to carry shit to the elsan or carry shit around in a tank below his bed thats fine by me but what will he do when he gets frozen in? I can change the bin and do another 3 months can he? As I say I have had both of the other systems and found them wanting this works so I will stick with it rather than get covered by sticky shit when the cassette glugs back on emptying which happened to a mate

Thats interesting ! Overboard discharge is prohibited on the non tidal Thames and I think I read somewhere that it has also now been made an offence to discharge sewage (from a boat) into the tidal part through central London. Thames Water put a lot into the River but hopefully this will be addressed by the tideway tunnel. With thd Thames in mind - I have no idea if that will remain the status quo, hence why I went for a macerator along with a diverter valve and tank (which I'm yet to have made - its location is storage for my other bits and bobs during the refit) a manual jabsco type toilet would have not been the answer (although way cheaper - particularly if straight overboard with no diverter)

For those interested ...... I made a few phone calls last night and managed to get in touch with the barge owner on the Medway ....... She is a full time liveaboard and has had this loo for about 5 years now and says she is happy with it. With the name I googled it .......... www.sun-mar.com/prod_self_exce_ne.html

Good stuff. A couple of observations. General wisdom is the tank needs as much air as possible to aid aerobic breakdown of the waste, a 1 1/2" vent to outside is often better than a charcoal filter. I'm going this route with ours. What size is the pipe to the charcoal filter? That is the only way air can be admitted to the tank when it's being pumped out, the pumps create a good vacuum, you really want as near the same size vent as the 1 1/2" pump out fitting - leaving the rinse out cap off all the time during pumping out will help. When funds allow consider changing to this type of hose. www.asap-supplies.com/seaflow-butyl-sanitation-hose-38mmIt's vastly better than the white sanitation hose (vastly dearer too!) particularly in installations where waste can sit in the pipe - your setup is at risk of this, both on the hose from the toilet to tank and the pump out hose. Hoses are also effectively consumables and don't last forever. Have you got a check valve in the fresh water supply for the flush? Belt and braces to prevent any tiny possibility of contaminating the potable water. I'm starting on ours now, it's a shit job but someone has to do it PS, top effort on the video, a Yank has put a video of a jabsco flushing away a real, huge jobbie - once it's been seen it can't be unseen The vent tube is the same size as the pumpout one. I ended up with this stuff www.leesan.com/shop/hosespipe-and-fittings/sanitation-hose/dometic-sealand-odorsafe-plus-sanitation-hose-1-halfinch.aspx# hose wise - not a lot of price differnece between your stuff and it though so fingers (or should that be legs) crossed it'll be ok lol The Jabsco kit says the solenoid contains a built in check/non-return valve.... you can't see it in the photo but the "flexi" pipe I used has an isolation valve in too so I can turn it off. SO far so good. No sign of any smell ... mind you, the coal smells so bad I may be "nose blind" ;-) ) Well, it looks like you've got all bases covered - difficult to tell on my crappy phone! It's so tricky to know what hose is what, this is similar stuff with the same claim to prevent odours. www.asap-supplies.com/seaflow-reinforced-waste-water-hose-507038?nosto=nosto-page-product1I think it was PBO that did a fairly good test on all the hoses available and the butyl stuff came out top. Nothing worse than a stinky head

Excellent tutorial but I won't be replacing my Thetford with one of those any time soon... Once a week stick the cassette in the boot of the car, drive for 3 minutes, empty it out, drive 3 minutes back. Plus loads of space under the bed to store things other than shit. I'm stunned by all the effort that goes into play with 'holding' toilets on boats, a Thetford plus spare cassette (if you want to be luxurious) is the way to go for an uncomplicated life. Also, with a Thetford, to save the lower part getting filled too quickly, you can place a bin liner or Tesco's plastic bag in it, do your business, tie up the bag and lob it into some trees beside the towpath. That's what all the dog owners do. It's the new craze, everyone's at it!!

Mrs Gazza seems to think my favourite part of boating is emptying the Thunderbox, elsans are few and far between in our neck of the woods - space for a a spare cassette is at an absolute premium. With the prospect of another female joining in the see who can fill the toilet the fastest game something had to change. I for one will be glad to be freed from the shackles of the thetford craper.

Something else you spouted off about without knowing anything about.

quaysiderCould you have fitted the tank on a slope to make emptying more complete? Do you have any plans to fit a level or contents gauge? Anyway, congratulations on a tidy job! In my marina, the pump out runs for 7 minutes. I time this on my watch so that I turn the flushing water off a minute before the pump cuts out. I also 'rock the boat' to loosen up any sediment. If you use yeast or proprietary enzymes this should turn the floaters into liquid. Watch for the charcoal filter slowly blocking up. It's ten quid for a pump out here, not bad.

I'm sorry but I'll stick with the Thetford.
Simple and nothing at all to go wrong.
No drain on my batteries, and as I'm on canals, it's just a call at an elsan as I pass by every three or four days.
Using blue is the only down side, but I've tried the alternatives and blue actually works.
On a mooring I can see the composting loo working fine (although you're still emptying liquids as often as I) but for cruising........

All the other biological and eco friendly solutions don't seem up to scratch to me. We've been using this of late www.onechem.eu/onechem-outdoor-leisure/cassette-toilet/ , good results with it - take two bottles into the dunny? not me, i just tip. shit and go Not having a bottle of that horrible stuff on board will be a bonus too

Something a bit different. I have a vacuum cassette bog and spare cassette. I thought it the devil's work initially, but I persevered and now I like it. It uses no chemicals, no yeast, it's odourless, it's easy and clean to empty, it has a porcelain bowl and a proper seat, like a "real" toilet.
The only complaint is it was fitted with the vacuum cassette part under the bed when it could have been in the bathroom which to my mind makes more sense (nobody really wants a container of effluent under the bed?) but it's compact and takes up little room.
