You know the plastic 5 gallon water dispenser bottles for offices and the like. What could be used to cap/seal them off if one wanted to just refill one themselves? I bought a 2" Fernco rubber cap that I thought would do OK, but the rubber, or neoprene stinks like crazy! Wouldn't do well to get the water tasting like that!

Can you machine up a nylon cap and fit an O ring seal? Not sure if internal or external would work the best - depends on the neck profile.

How 'bout a great big natural cork?

Homebrew supply stores have large rubber stopper. I'm sure I have a carboy that has an opening close to 2"

Cost about $5 or so IIRC.

Go anywhere that sells wine making supplies. They have rubber expandable stoppers with a metal lever on the top that is used to seal wine carboys. They should fit.

Hmm, missed the above post as I had this open for a few minutes before answering.

I think you'd want to be leaning towards materials that would meet the NSF standards. http://nsf.org/
Something made for use in wastewater piping would not.
