JWR:
A reader recently enquired about using water cooler jugs for long term storage. You suggested taping the original cap to the jugs. I’d like to mention that 55mm snap-on reusable caps can be purchased very inexpensively on eBay. They are not water tight i.e. if turned on its side, water will slowly leak but the caps are adequate to keep out dust and allow transport. 55mm is the standard size for most 3 and 5 gallon jugs. – George C.
