Jabsco Electic flush toilet - constantly filling!

[thames cruiser]

My electric toilet is constantly filling with fresh (flush) water. So right now I am having to switch the freshwater pump off when not actually using taps or toilet.

Does anyone have experience of this fault and what part needs to be serviced?

Thanks.

Firstly, standard flush or quiet flush?
A) Quiet flush.
Water from your pressurised fresh water system must be weeping through the pump impeller. Replace impeller.
B) Standard flush
Water must be weeping past the impeller at the back of the bowl that draws in flushing water. Replace impellor.

I'm guessing you are having a slow filling of the toilet.

HI try www.cleghorn.co.uk or Google cleghorn waring. They are the main suppliers and if nothing else they might have some drawings on their online catalog.
If it is the later quiet flush and your main water pump supplies it then it will have a solonoid valve with an anti syphon loop which can bypass water.also I have known them to bypass when the boat was running out of water something to do with the water becoming airated I think.

You should have a solenoid valve that opens to let the water through, it will fill through the pressure from your domestic water pump. Sounds like the solenoid is stuck open, can easily happen, bit of muck in the water or calcium builds up after a few years. Should be able to find it quite close to the toilet, maybe behind cupboard under sink. Easy to replace or service, Neil

Had exactly this with ours a few months ago. We found it only happened when using the top single rocker switch. It seemed to be sticking on the 'fill' operation so we simply stopped using that switch and just used the bottom two. It did the trick and now it just seems to have rectified itself. For info...on ours, we found access to the solonoid and electrics virtually impossible so just by playing with the rocker switches we found what the problem seemed to be.
Hope yours is that simple.

BTW...just as a matter of course now, we always switch the pump off and leave a tap open when we leave.
