I’m setting up an RODI system and I’m trying to decide what to use for a barrel. I’ve thought about just buying a rain barrel with the spigot already built in, however they are a little pricey. I’ve seen people use brute barrels and plumb in their own spigot. I’m interested in doing something like that, however I’m not sure the best way to plumb in the spigot to be confident that there won’t be any leaks. Any tips or tricks, suggestions???
