I've run in to this problem 3 times now, where I screw up and tomahawk my kite in to the water then a few minutes later my kite starts jellyfishing and I need to come in and pump up.
This has happened to me on 3 different LF Solo kites, a V1 and 2 V2's.
At first I figured it was because I never really screwed on the outer cap that tight because it's hard to unscrew (almost impossible with cold hands). Since then I've started screwing the cap quite tight but I still had it happen again yesterday.
What I'm assuming happens is the impact of the tomahawk forces the rubber flap of the MaxFlow to swing away from the seal. Now if the outer cap wasn't on at all this would immediately re-seal as air started rushing out but because the cap only allows a trickle of air out it isn't enough to re-seal the rubber flap.
All 3 times I've simply pumped the kites back up and they hold air all day.
In the past I've had similar problems to this with 1-pump systems that only leak when the tube is at a certain angle but I've checked the 1-pump tube and it's not that.
Anyone else having this issue?
One thing to note is I pump my Solo's up to 9 or 9.5 PSI.
On one hand I'm happy the bladder doesn't pop but on the other hand I could be facing an hour swim or 2 hour walk in certain situations.
You can see the tamahawk that cause it and the result in my video here, it wasn't even a hard tomahawk:
