DIY Guide: MLT from Igloo 10-Gallon Commercial (yellow) Water Cooler
Let me start out this DIY guide by saying that the inspiration and instructions came almost verbatim from FlyGuy's original thread (https://www.homebrewtalk.com/f51/cheap-easy-10-gallon-rubbermaid-mlt-conversion-23008/). FlyGuy saved me multiple hours of making repeated trips to Home Depot in order to get all of the pieces for the build and I thank him immensely!
I had to change two or three minor things from his build in order to get a good tight seal to ensure no leaks on my Igloo 10 Gallon Industrial Water Cooler.
I'll start out with pictures of the final product and of the final inside view. I have also included a pdf document in case you would like to print the instructions out. It won't let me upload the pdf that contains all of the pictures for easy printing, but just PM me your email address if you would like them and I will gladly supply them for you.
Here was my parts list (again, thanks to FlyGuy for these product Cat #'s):
Here are the parts you will need for the conversion (see images 2 and 3):
