Hi all,
I realise this is a ridiculous question, and I feel pretty stupid for asking it, but in attempting to inflate my presta valve, I unscrewed the nut and proceeded to deflate the tyre in about two seconds. I have followed online advice - unscrew the nut as far as it will go and then inflate, but I cannot get the pump to lock onto the valve and air is escaping rather than going into the valve. I have the correct pump. Am I doing something fundamentally wrong?
