I made this super high technical drawing for your viewing pleasure.
Anyway what do you think, anything I can improve on? I would like it to stay simple. Basic principle is that tank water goes up, through the sump, overflowing to the fuge... and overflow from the fuge comes down to the main tank. In event of power outage the water flow would stop after a couple of gallons worth.
The stand would be totally DIY
, I guess. I haven't really seen any like this around that I could buy.
Your thoughts would be welcome!
