Great job Glen, well explained & tidy set up. Rookie question as myself and plumbing have a passing acquaintance, does it not need a pump to get UGH up the height to the tank?

The toilet has/is a built in pump... Which is good enough to get it up to it. Once in gravity will do the emptying...

Hello from France. The second 3-ways valve(on the right in the video) is mounted in a reverse manner : the flow FF is coming from the top to the sea in the bottom. So that the flow is in the opposite way accroding to the "arrows" visible in the valve. do you think that is problem ? Many thanks. Stefan from France

We've not had an issue so far... But well spotted.
