We have a
Jabsco electric toilet with a flush panel (pardon the pun) in our shower/toilet compartment. the panel is waterproof and we've had no problems after 6 years daily use.
One point worth mentioning is that
electric toilets are very susceptable to human hair which gets itself wound around the
electric motor shaft
seals, destroying the seal (and motor). Some ladies use a hairbrush and then a comb to clean the hairbrush and throw the hair in the toilet = disaster ! place a small bin in the toilet for such items and educate any visitors. In hard water areas toilets and discharge pipes can become blocked over a period of time with limescale or Urea acid scale. To remove any deposits pour a quart of white 8% strength vinegar into the toilet,activate the
pump slightly to allow the vinegar to reach the discharge pipe
interior, allow to stand overnight and flush with clean water. Repeat every 6 months to keep toilet/pipework clean and free of scale buildup.
I hope you find this helpful.
