smitch6 Posted June 23, 2020 Share Posted June 23, 2020 Sorry for the topic but i have had problems, I have a jabsco manual toilet, it has the rubber choke, tried a flat 1 and a 3 way 1 from jabsco, when you have a poo it gets stuck in the toilet, so you're pumping the handle and the water just comes up, nothing going down the pipe. i've tried emptying it and nothing happens there either, i would suggest it's getting stuck in the rubber choke thing can i remove that? it's not under water so i haven't got to worry about feedback etc Quote Link to comment Share on other sites More sharing options...
Vaughan Posted June 23, 2020 Share Posted June 23, 2020 This sounds like the 4 sided flapper valve that is in the flange of the outlet pipe at the bottom back of the the toilet.Β The valve is known in French as a bec de canard - or duck's beak. When you see it, you will see why! You just undo the two nuts that hold the flange coupling and it comes apart easily. You may also need a new piston seal. All these come in the standard kit.

Smoggy Posted June 23, 2020 Share Posted June 23, 2020 Where does it go to? Tank or sea toilet? Are there any other valves in the plumbing like a diverter valve that gives tank/sea option. Quote Link to comment Share on other sites More sharing options...
ZimbiIV Posted June 23, 2020 Share Posted June 23, 2020 Looks like a blocked pipe then. Now its hot thats best time toΒ change it but get the proper pipe. Or take plenty of sennaΒ pods! paul Quote Link to comment Share on other sites More sharing options...

ZimbiIV Posted June 23, 2020 Share Posted June 23, 2020 Does it eventualy flush, if so see below. The only other time I have heard that happening the owner was using top quality toilet paper when for jabsco cheapest is best. It takes a while for good paper to soften. If your finger don't go through it, it's to good. paul Quote Link to comment Share on other sites More sharing options...
smitch6 Posted June 23, 2020 Author Share Posted June 23, 2020 no we have to get an old battery cable and shove it through........ yep not a nice thought, but thats the only way it seems to go yes we do use good paper lol Quote Link to comment Share on other sites More sharing options...
SteveO Posted June 23, 2020 Share Posted June 23, 2020 We had no end of problems with our heads getting blocked so went "Greek" around 4 years ago. i.e. loo paper goes into a bin after use. Since then we have had no recurrence.Β 1 Quote Link to comment Share on other sites More sharing options...

If you mean itΒ continues toΒ fillΒ with water when it should be evacuating it mayΒ beΒ a problem in the manualΒ pump head.Β There is a flap valve at the baseΒ of the piston tubeΒ if its not continuing to fill my guess would be that itΒ has failed.

ChrisB Posted June 24, 2020 Share Posted June 24, 2020 We had a similar problem on a charter yacht (Balearics). The engineer that came out poured a whole bottle of washing up liquid in the toilet bowl and pumped it through. It worked fine for rest of the holiday!Β Quote Link to comment Share on other sites More sharing options...
ChrisB Posted June 24, 2020 Share Posted June 24, 2020 You can buy quick dissolving paper for use with Caravans and RVs but all the boating and camping forums say that the very cheapest recycled supermarket 2-ply is just as good.

ranworthbreeze Posted June 24, 2020 Share Posted June 24, 2020 We have a policy on Ranworth Breeze where all the toilet paper used is supplied by the syndicate throughout the year so we know that only that two ply toilet roll is used, contraband loo roll is not allowed.Β I agree that theΒ Β joker valve and the paper used will be the issue, also never allow any kind of wipe to be put into the toilet bowl. Only use smooth wall pipe for the outlet into the tank, ribbed pipe causes problems. Regards Alan 1 Quote Link to comment Share on other sites More sharing options...

annv Posted June 24, 2020 Share Posted June 24, 2020 Hi Does the water pump away or does the water level rise if water pumps away stool is to hard if water level rises you have a restriction remove breather pipe 3/4"dia one and check not blocked the gauze on hull fitting can get blocked also tip some VEGETABLEΒ oil down pan this will help to lubricate make pumping easier, to check stool tip a can of soupΒ down to check operation.

SteveO Posted June 24, 2020 Share Posted June 24, 2020 As a slight aside, I believe that the British Standard for lavatory pans included a "flushability" test which involved attempting to dispose ofΒ a 1lb Dundee cake.Β I have never looked at fruit cake in the same light since I heard this.
