I'll be glad to help you sort out how to do it right...What's the make/model/age of the toilet?
I am installing a Marine
Elegance and the toilet discharge points straight down. Since my holding tank is about 4' above the toilet discharge, I have no choice but to route
the hose down before going up.
The outlet from the macerator points up and then goes into a 180 degree vented loop which exits downward. Thus, I will need to make another 180 degree bend on the waste hose to route
it up to the holding tank. The fitting within the Marine
Elegance has a vent at the top of the loop, to be opened only if the unit is installed above the waste tank. In my case, the manual says to keep the vent closed. On the one hand, I can see that this loop will serve to prevent waste in the hose from backing into the bowl (there is a joker valve at either end), but on the other hand, this serpentine exhaust
route doesn't seem optimal. I'd love to hear your thoughts?
