Try a low calcium diet.
I have 2 Jabsco electric toilets on the boat. One is a belt drive and the other is a more expensive direct drive. Sorry I do not have the model numbers. They call them a quite flush, but I think the guy that tested them must have had a hearing problem. Do not get the model with the belt drive as they break the belt drive cog on a regular basis, go for a direct drive toilet. I think most of the toilets that have the rubber non return valve at the base have the calcium problem. I find if you give the toilet 3 or 4 big flushers each night it keeps it at bay. But about every 6 months I pull the toilet apart and clean everything with acid.
Jabsco seem ok
I have two on board pumping through holding tanks and have had no issues
My next door neighbour.....he has a million dollar 47foooter, uses Brick Clean every few months.
He used to live aboard with his wife so the toilet was regularly used and tended to clog after a while.
He swears by the Brick Clean method and it never did any harm.
Dare I suggest a composting toilet, Airhead, Nature's Head, C-head (the cheapest, simplest and the one I'd buy.)
No through-hulls, no holding tanks, no hoses, Y-valves or pumps, no clogging, no stink.
You have to empty the pee bottle every couple of days, and empty/replace the bucket with the poo every month or two, depending on number of daily uses.
Maintenance is virtually nil, you'll need a brick of coconut coir or peat moss every couple of months.
You can buy a urine-separating toilet seat/pan from Privett for about $100 and make your own.
Google "marine composting toilet" and settle in for few days reading............
This is another part of my refurb...apparently the old bucket doesn't suit the female on board
I was thinking a compost camping toilet would suffice?
Hi
We dont live on our yacht, our marine toilet/head always has this issue from the salt water. Every time we go to our boat I use 1 cup of vinegar and a few drops of sunflower oil. Allow it to sit for about 2-3 min, ours is manual so I, 1/2 pump the toilet and allow the solution to sit. I continue until all the solution is gone. Finally flush with sea water a few times to remove the vinegar. It should work well now. This is safe to pump into the sea water. This works well for us and is pretty quick and cheep. Good luck.

The TMC electric is about as good as it gets. The rest just cost more money. I ran a TMC electric chartering for 2 years and only had to rebuild the electric motor twice due to salt water and p!ss getting on it.
The latest TMC dunnies have a plastic guard shroud to counter the splash. You can buy them from Road Tech Marine (the new competition to BCF) for $229, a discount of some $70.
It does not matter which brand of dunny you have, they will all be subject to calcium build up. Given your vast experience of charter work I thought you would be aware of that. Any capable yacht master or engineer would know that part of his/her duties are maintaining the sewerage system of the vessel, be it unclogging stubborn turds, excess toilet paper or bloody tampons dumped in the toilet bowl prior to sex.
That duty is aside from being chief cook, bottle washer, bed maker and arse wiper.
Both the cruising yachts I owned had the normal manual marine toilets I converted both of them to the Lavac system by fitting rubber seals to the lids and a good size
diaphragm pump to pump the waste to a holding tank which then gravity fed when required through the seacock overboard
They worked well for us as liveaboards over quite a few years and were far better than the original
We also used vinegar and a dash of vegetable oil occasionally to keep the calcium down but had to remove the hoses on occasion to clean them
The latest "lite flush" by Jabco look interesting, they sound quieter and use less water on the utube video.
My concern is how many house batteries do you need on the boat?
How many batteries do you have on your boat?
My Jabsco works perfectly if a little noisy. I always put the toilet conditioner from Whitworths in it
at the end of the day. Never any trouble.
The previous owner of my boat fitted a porta-potti that can be pumped out that works quite well and should comply with the rules. The original hand pump operated tank contains freshwater and additive for a flush of the bowl and the holding tank is fitted with inlet and outlet pipes through the hull and a 3-way valve. When its time to flush I run the macerator and recirculate until the contents have the consistency of hospital quality soup and drain. I then let in some clean seawater macerate and flush again and then let a small amount of seawater back in to provide a bit of dilution for the next load. The holding tank doesn't have huge capacity and will leak onto the floor if overfull and I haven't tested it in heavy seas but I imagine it would have to drained more regularly.
Hi, southace
I read your problem and only one suggestion that strikes my mind is that you must contact web sources like www.theportabletoiletcompany.com.au/ to purchase the folding portable toilet. As they are pretty easy to use and you can easily dispose off the waste also. Above all they are very reasonable in price and easily available in all types’ of shapes and size. You can make a choice according to your affordability and usability.
