Jabsco toilet problem

[Adethefridge]

My 12volt jabsco toilet is playing up again
About a year ago I replaced the sized motor with a complete unit, basically everything from the pan to the intake/waist hoses, now it appears to be drawing in sea water quicker than it's pumping out !
In throttling down the sea cock I can restrict the volum of water in to match the rate at which it pumps out, from memory it's the same impeller drawing water in as it pumps raw water out ?
So before stripping it down I thought is see if any one else has experienced the problem ???

There are two impellers on the same shaft on my Jabsco conversion.

I dont think so!

Several different versions/conversions though.

Exploded diagrams of them all on the Jabscoshop website http://www.jabscoshop.com/marine/marine-toilets/toilets/

I would guess that we are talking about a 37010-series toilet. This has a flexible impeller to bring flush water in and a centrif impeller to evacuate waste both on the same shaft. Usually, it should remove waste quicker than it can fill (as in practice, the toilet will be filled in use!). A lower flow on the outlet, as it is a centrif, (which typically have a low pressure head curve), would indicate some sort of restriction on the outlet pipe (kink, scale etc)....

That is all assuming we are talking of a 37010 toilet. The clue will be the control button, a single black button is a 37010 toilet.
