Firstly, can I apologise if this has already been covered.

We live aboard (in the UK and Europe) on a catamaran which has four toilets (excessive I know but she was a charter yacht!). We tend to use one of them all of the time and the others occasionally when we have the family on board. They are all Jabsco manual compact toilets. About two years ago I replaced the pumps on all four of them with the twist and lock type when we moved on board full time.

Since then I have done nothing put replace parts of the pumps, the twist mechanisms go, the flush/empty levers jam and, on the one that is used the most, eventually becomes too stiff to actually use. During the last two years I have replaced most of the components and eventually, last spring purchased another complete pump assembly.

After about six months of operation this has now also pretty much seized up so I am back into the routine of replacing parts, or most likely replacing the entire pump assembly. I then contacted Jabsco to ask what on earth as going on and was told that the toilets are not designed for live aboard use and are intended to be used occasionally for a few weeks a year (they suggested four) over the design life of the toilet which is apparently five years. This implies a life of six months, which to be honest is about what I am getting.

This is crazy of course as it means they are suggesting a new pump assembly twice a year which at around £50 a time is not insignificant. I did mutter about ‘not fit for the purpose’ but these are apparently ‘leisure’ products.

Has anyone any thoughts on a sensibly toilet I could retrofit without too much pain that might work for a little longer, or better, am I missing something obvious on the maintenance?

Strange you are having such problems. We are liveaboards and have no problems with ours. Mind you, as part of my monthly maintenance routine I do give the pump a squirt of WD40.
Might work for you as well.

Where do you squirt the WD40....
and does the manufacturer recomend it?

Have a Jabsco. Two of us have lived on board for 5 months per year for past 3 years. Apart from periodic use of hydrochloric acid or white vinegar to remove "limescale" et al, plus weekly dose of olive oil as lubricant we have had no maintenance issues apart from replacement of the joker valve after 2 years.

We also put white vinegar down the toilet once a week. We also put a short squirt of cooking oil down twice a day to stop the pump becoming stiff and and it seems to lengthen the life of the choker valve. Not sure why, maybe it keeps the rubber flexible.

We normally have to replace things about every 18 months but we are using it every day of the year. I have to say though they are badly/cheap and nasty made. Only a lunatic would put self tapping screws into plastic although many boat products do that. Jabsco pumps for example - oh look Jabsco again :)

We spend the Winters (insane I know but work means I must!) in Swansea. This is in a marina but is actually on the river behind a tidal barage. The water is very muddy a lot of the time.

I wonder if the problem is the amount of silt going through the pump? I asked Jabsco about this and they said it would make no difference. I guess I could either run with fresh water in the marina or maybe put some additional filters in?

Surprised you have so many problems. True they are not the best made bits of kit, but ours survived 7 seasons on charter with only routine maintenance.

However, the solution is Lavac. Much simpler and more robust with added benefit of generally more economical on water so reducing load on holding tank. Can be difficult to fit because of layout of pump and piping.

We are permanant live-aboards and also have the twist and lock jabsco toilets. We were a bit concerned as they soon got stiff and difficult to use. Now they work like majic. My answer to the problem was to flush with a little olive oil once a week. Whatever you do, DO NOT PUT WD40 down as it makes it worse...Dispels water and drys it out.

Happy Sailing

I had jabsco manual toilets, they were fine, yes required servicing once a year, for permanent liveaboard, a little oil kept them free. I used soluble mineral oil as reccomended. Now have jabsco electrics, three of them, no trouble in two years.
I use soluble oil in them and dose with hydrochloric acid every month.

Out of the mouth of babes

Sounds like a tremendous endorsement for Jabsco.
I once heard a similar story from Volvo marine, who stated that their engines were designed for 100hrs per year.

Jabsco

We have recently jettisoned two existing 'compact' Jabscos that we couldn't get on with (if anyone's interested they are awaiting a 'boat jumble' albeit down near Toulouse). Too blimming small in the seat department, like perching on a flower vase! Replaced them with one new Jabsco standard size (the other heads has become a dedicated shower room). It gave us problems from the start and we wished we'd gone with a Lavac (we had had one on our yacht for years).
However, we discovered the cause of the trouble (our particular problem - not flushing out properly). It is vital that the outlet hose has an upward loop - does not go straight from the toilet outlet elbow downwards.
Now seems to be operating aok.
Fingers crossed ;)

Olive oil sounds sensible. Has anyone got any views on vegetable oil.....or washing up liquid?

Washing up liquid seems to work in my Lavac. As does Vanosolve for the harder scaling.
However the pumps need cleaning more frequently than I can get enthusiastic about.
I think it's a good idea to have two pumps and rotate them for leisurely servicing.

Hmm my advice is not to use washing up liquid as it has a slight acidic base to it and after a while the 'O' ring on the plunger will dteriate. As for other oils most will be OK

Peter

I did hear somewhere, that olive/cooking oil is not good for the seals etc, but not sure where I heard it, which is why I use soluble/lathe cutting oil.

We liveaboard and have a Lavac. It's great - blocked once, due to scummy build-up in the pipes/pump. Service kit installed, it works like new, simple stuff.
