Dunlup valve compatible floor pump (aka Woods Valve, aka English Valve)
Some pumps don't work with Dunlup valves...but fortunately some do.
My Walmart Zefal floor pump doesn't...but my Topeak G Morph mini pump does.
Let me know if you have tried a Dunlup valves on a floor pump that works and let me know the brand and model.
Because the Great Flood of 2017 ruined...
