Coolers for Salt Mixing

[Soggy Frito]

So, been doing research on a salt mixing station and am considering building one with coolers. Please tell me why:
A. It's a great idea, you did it and it's awesome
B. It's a bad idea, I am a knucklehead
C. You're going to grab a drink, some chips, and see what happens

I have limited space where I plan to build my mixing station, so the Brute cans or big drums are out. I was in Bass Pro recently and saw the big Igloo coolers and a light bulb went off. I could stack them on top of each other, use the drain fitting as a discharge, big open lid for ease of adding salt / cleaning, food grade materials, etc. The big ones (in the store - certainly more options online) would hold ~30 gallons, which is about my goal and they cost less than a 30gal "tank". I'd have to drill and seal up a couple holes for RODI fill and possibly return piping, but would have to do that with whatever vessel I used.

So, anyone done this before? Any good reason not to try it? Appreciate any ideas!

I'm leaning toward a solid C.

Have you ever tried to get a beer out of the bottom cooler?

Otherwise, I was thinking you were trying to hook up a chiller (cooler) to a Brute salt mixing station and I'm going back to my chips now. The container should work fine, otherwise, as long as you can get it sealed properly.

So, moved ahead with the project and here is the result. Tested it in the garage for leaks, but that is it so far. Still need to install a float switch in the lower cooler for the RODI inlet. @KrisReef -you are right, getting a beer out of the bottom cooler will be tough, will have to finish the top cooler first...:face-with-tears-of-joy:
However, I did put in a couple of unions to help with disassembly.

Looks good!

How did you seal the pipe to the cooler?

Coolers had a 3/4" threaded outlet. So, I used a 3/4" threaded ball valve. I then used a thread to slip adapter to go to the pipe. Everything is either thread w/ teflon tape or glued PVC.
