I have read about this SS valve problem a bit, on here and other forums. Waiting for mine to go (hope not!) Seems to be rather unpredicable when they will. Good one minute, not the next.

I am sure they would love the free publicity of their good service for helping you out. It really is a fault of the kite by the sounds of it anyway. No prob if the manufacturer looks after you.
A little tip. Having just replaced bladders on my North, I would recommend you only remove the ones you need to for fixing. If you can't hear them leaking don't pull them out! Cheers.
