For many years, smaller boats have only had manual marine toilets installed on them. These toilets are generally fitted with hand-pumps for their operation. These pumps work in two modes: Firstly, the rinse water is pumped into the toilet bowl and then the contents of the toilet bowl are pumped out by turning a switching valve.

Advantages of on-board toilets
The advantages of manual marine toilets are their low price, easy operation with appropriate care and maintenance and the easy procurement of spare parts. In addition, no on-board power is required for manual operation.
Disadvantages of manual marine toilets The disadvantages include operational problems resulting from usage on charter yachts and with smaller children aboard. Uncontrolled water consumption, in conjunction with small holding tanks can also be problematic. Often too much water is simply pumped / purged and the holding tank fills up quickly. The rubber parts (seals and valves) of these units must be properly maintained, in order to keep everything operating smoothly.
Electric conversion kits for on-board toilets
The solution for retrofitting a manual toilet into an electric version is an option for some brands. A decision must be made between simply replacing the existing hand pump or the entire substructure of the unit. Both systems are equipped with a combined chopper / impeller. The need to manually switch between rinsing and suction is eliminated and the toilet is much easier to operate for less experienced sailors.
