My habitat is a four season design and all water tanks are inside under the dinette benches. Therefore to get water to flow up hill into the grey water tank there is a 12v sump pump. And I guess there is a thin water tank under the shower floor drain, but am not 100% sure.
(still investigating)

Does anyone else use a sump pump?

My friend used a sump pump to move shower and sink water 'up' to his gray water holding tank in his FM-260. No issues although he did have a macerator in-line upstream of the pump. He might have a write-up in one of his posts ( search JRhetts )
