Found these yesterday. Each holds about 5 gallons. Bottom drain, all stainless, about 1 and 1/2 inches of insulation. Thinking about a false bottom for a mash tun. Problem is the openings are only about 5 inches. Any suggestions?
What's the bottom drain look like? guessing it's sanitary, flush with the bottom of the vessel? I see a side drain in the pics, I think. Perhaps you can remove that, install a threaded bulkhead and then drop braid down in there. The bottom drain is mostly handy for cleaning. It means you can clean in place because your water can drain fully without tipping the vessel.
