    Got all my water working, now need to suss out how this waste system works. It seems to have a Thetford Slide Valve, and everything (sink water to toilet waste) comes out of this pipe. Can someone please explain how this is supposed to work? Am I missing something? There doesn't seem to be any kind of waste tank, only this outlet.

    Ok, just had another look underneath, and there is 1 tank, dirctly under the loo. The way it seems to work is this:
    The loo waste goes into the tank, and can't go any further until you open the Thetford slide valve.
    The sink/shower waste heads to the same outlet, but byepasses the Thetford valve.
    I reckon you would place a waste tank under the outlet for the water waste, which would freely drain into it at all times, and then when you want to drain the toilet waste tank, you unscrew the small bore outlet cap, then open the Thetford valve, and stand well back!

    Can anyone confirm this? :thumb:
