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
, 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.
