I wouldnt have either a pumpout or cassette in any boat I owned for to many things to go wrong, you are always emptying them and they are so crap! No composting loos are the future for any sensible person You forgot sea toilets.

But where do you store your solids for the 6 to 12 months it takes to compost?
And don't you have to run an electric fan 24/7 to dry them.
And I presume you have to empty your liquid container every couple of days.
I really struggle to see the advantages of composting loos at the moment (on a boat).

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" ;-) )

Rog It takes up to 3 months for the solids to fill up wee into a 25 litre container which I empty onto the very green grass not very often poo goes into friends composting bin straight away, puter fan to blow air over poo doesnt even register on the nasa so whats the problem? Like Cris I could never go back to a pumpout or cassette just to much hassle but the sea toilet mmmmmmm

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.

Rog I too have grave concerns regarding storage of all this shit and piss, however when I raise them I am jumped on by the 'compost' evangelists. Having researched the subject it would seem that most 'composters' throw the fruits of their ass down the nearest elsan, one maintains he collects and stores all his shit on his live-aboard for the full 12 months required for proper composting and one says his friend allows him to dump it raw in his garden. Frankly it all seems so pointless.

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.

My favourite sea toilet so far was the Blake Baby, Pump out with one hand while flushing with the other and they macerate at the same time. They do need maintainance though, especially the sea cock and the washer on the flush which can allow ingress if not looked after. That worrying feeling you get when you lift up the lid and find the bowl full of water.

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?

That worrying feeling you get when you lift up the lid and find the bowl full of water. Its a beautiful thing. I did think about putting one of them in my barge for the ladies but went for the Lavac (going to a holding tank) as it was a new unit. The Lavac has been a very good toilet as it happens.

The wood makes it look very handsome.
Weird thing to say about a loo I know.

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

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.
