Electric Toilet
I am getting ready to replace my Raritan PHEII with an electric toilet. I am inclined to go with the SeaEra by Raritan or the Jabsco Quiet Flush. These two models have a small footprint (essential in my head) and are supplied by the pressure water system. Since the boat has a watermaker I am not terribly concerned with using freshwater. Anyone have a suggestion before I buy?

Electric Toilet
Any connection between potable water (pressure water) & the sanitary system (head) must be adequately isolated - ie: back-flow, or cross-contamination prevention.
Make absolutely certain that you understand and apply the principles of cross-contamination prevention, prior to plumbing your domestic fresh-water into the new electric head.

What is Backflow and Why Should It Be Prevented?

Backflow is the flow of any liquid or contaminant back into the potable water supply. This happens by either back-siphonage or back-pressure. Water can be siphoned into the water supply if there is a drop in supply pressure. Back pressure might result from a pressurized system directly connected to the water system.

In other words, water from your water-closet (head) MUST BE PREVENTED FROM being drawn back into the potable water system by siphon, pressure loss, or any other means. The backflow prevention device is used to keep water that passes through it, and into the head, from coming back into the potable fresh-water supply.

For a general description of typical back-flow prevention devices, goto:

Electric Toilet
I have a Jabsco electric toilet. It has performed flawlessly. It is actually pretty miserly with water. I use seawater so I''m not concerned with the supply, but we don''t dump overboard so the rate of fill of the holding tank is of concern. The repair (WHEN it happens) is more of a burden than the manual. If you can spring for the complete repair kit with motor - repairs are easier or at least down-time will be less.
