This is interesting to know, because a lot of pumps are press on chucks, and this is the first I've heard of this issue with latex tubes.
Thanks
Yup, I was pressing the valve down against the pump chuck on one side, and rim on the other, against a partially inflated tube. My guess is that pressure on the partially inflated tube gradually leads to separation at the glued joints (or whatever method they use to seal the patch of latex around the tube to the rest of the tube).
So now I usually try to remind myself to either deflate the tube completely before pressing on the chuck, or use a mini pump with threaded chuck to top up a mushy feeling tire.
