A few years ago I purchased a Blitz 6.5 Gallon Water Can just in case we had a major hurrican that would knock out power at the house. Though I did fill it a couple of times we did not end up using it (yet).
But one day I lost a cap to a gas can and was in desperate need to replace it. I discovered that the water can’s cap would fit perfectly and so that’s where it ended up. Of course, once used on a gas can it simply wouldn’t be good to use on the water can again.
This year I decided to bring the can to our apartment to prep for hurricane season but unfortunately it still lacked a cap.
