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.

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.

Service

check the fresh water feed tank to the toilet is connected correctly and is that tank steel as it could be rusty ! ??

Check the power source to toilet and all wiring conversed.

Hi
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.

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.

dismantle the pump and put some waterresistant grease on the o-ring of the pump, problem solved
