Ok get ready for some country boy engineering 
(Prob overkill HAHA)
Here are the pieces i will use
I looked at the auto-pot to see how the AquaValve sits in the container and i tried to mimic it roughly. the valve sits up a bit and has a channel to the middle of the reservoir and then the pot sits the highest with parts going to the deepest groove.
I used some random plexi glass. any hard flat surface that’s sturdy should work for a platform. Then dremel out your design.
So Egg Crate or Light Diffuser panel is the perfect size to fit the AquaValve. So i cut a piece and just used super glue to attach the T that holds valve in place.
I attached magnets to the bottom of the AquaValve plate took another piece of plexi glass (which will attach under the container / tray to hold the valve in place) and after lining it up marked where i wanted the magnets and super glued them to the plexi glass plate.
RECOMENDATION* if using magnets you might want to get fairly descent strength to prevent the aquavalve from moving off center . Also if you use any metal-to-magnet instead of magnet-to-magnet to fasten valve plate to the plate that goes under the tray; DON"T USE WASHERS! the magnet will want to shift off center of the washer because the hole in the middle. use a flat piece of metal.
I took a sponge filter of a aquarium sponge bubble filter and used it in my water resivior for the 1/2" tubing upgrade.
Mine Tray Vs AutoPots Tray
- I got some GREAT info from people on ilgm forum on how to hook up the tubing with shut-off valves and quick disconnects. I believe it all came from this thread https://ilgmforum.com/t/should-i-kick-this-autopot-section-off/78021/17
- I also wrapped the AquaValve in a aquarium filter media bag (try to keep debris out of it) i saw that they had a Valve Sock and plate on Autopot website but said F-it.
OKAY THIS IS WHY I WANT A F^#Kn UTILITY OR LAUNDRY SINK!!! LOL, man always on my knees or bending over in the tub hurts.
AutoPot Tray working
MINE WORKS HAAHAHHA
this is how high my reservoir is compared to the trays
