Update #1 on DIY IBC rainwater harvesting system. There were a number a changes including expanded the system from 550 gallons to 1100 gallons, increased down spout from 2'' to 3'', installing proper adapters, replaced bricks with center blocks, and added unions to easily remove a tank if need be. I also share a few other small fixes that I had to figure out as I went; I hope they help you on your system! I will have more updates soon, as well as other helpful videos for rainwater harvesting.
