It has different sides for the valve in question? Interesting - my Blackburn Air Tower 2 just has one "side" and takes either valve with no problem.

If it has a dedicated Presta "side" that isn't working quite right can you return it for a replacement? Seems to me that shouldn't be happening with a brand new pump.
