Jabsco toilet fails to fill

I bought a used boat with a Jabsco toilet. I opened the valve to the open the line to the outside water and turned the switch on the toilet to fill. I pull the pump handle and get only air. The toilet worked fine last season. Any suggestions?

Was the toilet "Winterized" last fall? If so, have you assured that any plug in the clean water intake has been removed? If NOT -- are you sure the pump has not been frozen and internally damaged by ice? The pump is a simple device which rarely fail unless its inlet is blocked, or the pump seals or body are damaged - usually by freezing.

SOURCE: Have a Jabsco Self-Priming Macerator

Try removing the plastic cover, from the motor and turning the shaft that extends out the back of the motor. I used pliers and the macerator is working, now. My problem was that a pebble had jammed the impeller. Turning the shaft freed the pebble from the impeller.

Jabsco model 37010-0090 electric head. sometimes no motor run or flush when button pressed. By turning slotted shaft on end of motor , button then activates motor and flushes.

Sounds like the motor commutator and brushes need some attention. Not a difficult job if you have been there before but it can be tricky for a novice.

Hi, please help i recently replaced all seals and gaskets in my jabsco compact marine toilet, it worked well for two weeks when all of a sudden it would no longer empty the bowl. It pumps water in easily...

I don't specifically know your model of marine toilet but with my Baby Blake I have known the joker valve turn itself inside out (I think due to someone forgetting to open one of the seacocks) which meant that very little would pass out through it.

Toilet backs up after use. even when holding tank is empty. we only use fresh water to flush from shower nozzle. toilet is fairly new replaced by original owner.

The system does not work, as you describe, you MUST use the unit's pump lever as the intake and removal are part of it's function. Use sea water to flush, the system is designed for that.

I recently installed a Jabsco 18590 Run Dry mascerator pump on our Hunter 45' sailboat. It is very unreliable... sometimes pumps the holding tank and others it just runs dry - i.e it doesn't prime itself....

I would check the float switches,as these pumps are operated by the float switch.there may be 2,possibly they are not fastened to the inside of the tank properly , this would be my first impression
