Got a topeak track pump 18 months or so ago and has worked fine until yesterday.
Now when I lift the lever after putting the inflation bit on the valve air comes out from the tyre, even if I start pumping the air comes out faster than I can pump it back in?
I've tried not putting it as far on the valve and varying how far open the knurled nut on the valve is but all that makes no difference.
Do I need to adjust or replace something?

I'm getting this with my Blackburn. Still don't know why, seems to happen more on the road bike than the mountain bike. Tried a few things. Just a bit temperamental.
