I am trying to fix my Saniflo Saniplus macerator. It is the older model, without air vent.
I have already identified the problem, the membrane under the switch needs replacement.
One question: How does one close the lid? There is a rectangular black rubber gasket/seal, but it is very difficult to close the lid with the gasket in place.
Do you insert the gasket on the bottom part and then squeeze the lid on top or do you insert the gasket in the groove on the underside of the lid and then squeeze the lid with the gasket onto the main bottom part?
I've tried all different ways, even spreading some vaseline.
Many thanks,
Antonio
