Some tubes do have replaceable valve cores. There is a tool (used to come on lots of valves year ago) used to unscrew a valve core and replace it. However, if you take it to a bike shop, they'll probably just replace the tube.

If it's a Schraeder valve and you don't have a LBS you trust not to argue with you and try to sell you a new tube, take it to a motorcycle shop.
That's provided it actually is the valve core, and not the attachment of the valve stem to the tube where Owlie mentioned. You dunked it in water and all that I assume.Speed comes from what you put behind you. - Judi Ketteler

I didn't need to dunk it in water. I can feel the air coming out of the valve. Like when you push in the pin, only not as fast.
