Water Recirculation

Hello I am new to Wazer. I just picked up a desktop model second hand. It was in decent shape and I got it for a good price.
I know it’s not recommended, but I plan on doing a closed loop water recirculation setup. I will have a 55 gallon water drum with a pump going from the drum to the wazer fill. There will be a reverse osmosis water filter coming from the water drain back into the drum… I will update as the project comes along.

This will be the setup. The gray will be the wazer pump and machine. The brow is pressure treated wood. The blue is a 30 gallon water barrel and the green is a 5 gpm water pump.
