I just got 2 of these 20 gallon plastic drums from ebay.
They have these clamp on lids
Smelled to all hell like olives when I got them, but a 3hr soak in hotwater & oxy took care of that.
I'm trying to determine how to rig an airlock or blowoff and whether or not I want to install a drain valve or not.
I know I could just drill a hole and jamb an airlock in it, but whatever I do, I'd like to be able to cap off later. That's why I'm kind of thinking a weldless bulkhead through the lid to a blowoff tube might be better. That way I could just put a 1/2" NPT cap on it.
*Think a 1/2" opening is adequate for a blowoff?
*What size hose would be minimum?
I know if I add a spigot, I still won't be able to drop out sediment like a conical. It would be nice to be able to take samples, though and maybe for racking, but do you think it would be worth the added hassel of disassembly and cleaning... or should I just abandon it and stick w/ an autosiphon?
