If you own a Naish Park or any Naish kite with those Octopus valve systems, please check them now!
ie:
Pump it up hard and spray it all over the bladders, especially the connectors and valve areas, with soapy water. A bottle of Windex is quite good actually. If you see any bubbles, your Octopus system is about to die or is already - it's leaking air.
If they're the original valves from over 5 - 7 years ago - they are literally about to crumble... 
Just a warning because I've had like seven of these Naish kites, particularly the Parks, come to me for repairs in the past 2 months. The cost of replacing these valves with stick-on ones can become prohibitive and you have to buy the female and male version of those valves, plus they are a bitch to replace.
Fortunately 
there is a work-around. Convert the kite to one-pump. Way cheaper, but you loose the convinience of pumping the kite from the one Inflate valve.
Don't you mean to multi point pumping ? Isn't it a one pump kite in its standard form ?
I was bleating on about this exact problem months ago.
Have spent countless hours trying to source, and replace the bastards. While there were some successes the whole setup became too unreliable and you could never fully trust the kite again.
Classic moment when I finally got the NZ Naish distributor to get me replacement set of bladders, then first session out managed to snap my center lines! Gaaaaah!
Best thing I ever did was finally reach tipping point after that then got online and got a new switch to replace it. Would have saved me hours of time, missed sessions, swims' in with a half deflated kite etc.
Wiser for the experience I guess...
