Defective pump?

How hard should it be to remove the air pump from the presta valve? I have to wiggle mine back and forth to get it off. I have had 3 broken presta valves since I got my new bike in July. It is a Joe Blow floor pump I have had several years. I am trying to be extra careful now when taking it off, but maybe I just need to get a new one?

I'm sorry if this is a dumb question , but you are flipping the lock lever back down before you try to take it off, right?

I've broken some valves by wiggling the pump, but not with my floor pump, only with my small pump that I take on rides.

I've found success by flipping the lock to the open position and striking the pump with my closed fist (outside of my hand). One clean hit usually does it. This means, of course, that the position of the valve when you are pumping is at 12:00.

Not a dumb question, but yes, I am flipping it back down.
