Jabsco conversion pump not pumping water into bowl ?

[Al B]

Had some good info from others on this project . ?
I did not replace manual with electric . My motor was NG
Found a good deal on ebay . New old inventory including bowl
Same model Jabsco Conversion electric pump
Had few days too return . Did not want too rush job ,Wired too head wiring and motor ran . GOOD
Weeks later I did install Now having a issue
No water pumping into bowl ?
This is a question for techs at Jabsco but no human contact on their site
Maybe you folks can guide me
Fresh water goes from holding tank into top portion of conversion pump . ?
When I turn too fill portion it should pull water from holding tank into bowl .
Not too burn out impeller I fill bowl with water from shower hose . Motor chops it and goes into waste tank .
Opened top portion of conversion and impeller is new , turns fine
There is another impeller on bottom of conversion , would that effect water into bowl ? Have not removed conversion pump too check for bottom impeller. Since this pump was new old inventory never thought of checking impellers .
Does the top portion ( impeller )of conversion pump pull fresh water
Tank is full
I primed by adding water into fresh water hose and nothing . Don't believe any blockage in water hose but will check further
thanks as usual

From your description it appears your conversion is the Jabsco 29200 Jabsco 29200_Electric_Conversion It doesn't draw from the water tank--and don't even THINK of trying to connect that toilet or any other sea water toilet to it!--it uses sea water, same as your manual toilet did, which means the seacock on the intake thru-hull needs to be open. The owners manual should give you information you need to get it installed correctly and working the way it should. Jabsco 29200_Electric_Conversion

Peg
thank you for responding
you were correct .
Boat was on the hard when I installed new conversion pump .
Prior too motor burning out old conversion pump filled bowl but I was in water.
I always assumed water that filled bowl was fresh water from holding tank
My past questions which you responded too was flushing holding tank , cleaning , odors .
Put boat into water yesterday, and BINGO water entered bowl when fill was activated .
I am so used too simple projects becoming major that I assumed the worst.

THANK YOU

If you ran it very much before the boat went into the water, it's possible that dry friction heat may have "fried" the intake impeller. You'll know whether you did if the toilet decides to stop pulling in water in only a short time after you've gotten it working. See the owners manual (I sent you the link to it in my previous reply) for information on how to replace it.
