I'm fine with pumping my presta valve tires with a floor pump with the switch that connects and disconnects from the valve.
I bought a Lezene portable pump that screws onto the presta valve.
What happens is I loosen the presta valve, then thread the portable pump hose onto it and pump. When I unthread the hose the whole valve core comes out with the pump hose?
Is the solution to not thread the portable hose snuggly to the presta valve?
