Has anyone else had problems with the big dump valve at the tip of the leading edge bladder separating from the bladder ? My three Rhino05's have all done this in the last 6 months. I would try to blow up the kite wondering why it does not inflate. I would find that the valve on the end (which I only use occasionally to deflate and have never pulled hard on it) had completely and cleanly separated from the bladder. Not even any glue left behind.

All of my three Rhino05's have done it and always the same valve. I tried to get north to replace the bladder when it happened to the first kite but they refused because it was more than 12 months old and hence the warranty had expired.

Has anyone else experienced this problem ? I was going to get some new Norths but now having second thoughts.

Hey holgs,
I have'nt got an answer, but was talking to another forum member at a downwinder today and he wasn't particapaiting today because of what sound's like the same problem. How did you fix the problem on your other kites,I'll pass on the repair method if it's the same problem.

I have the same problem with an 06 Vegas, also heard it happening to 07 models also.

An easy way to repair, is remove the valve and put a patch over it. Won't last for ever though.

ring steve at kitepower...they have stick on replacement valves for about $25 or something. I had the valve go on my '05 and the new stick on valve works sweet, piece of cake to put on and a hell of a lot cheaper than frieghting it to a pro repair shop.

- kitepower also do cheap repairs to torn kites etc, got a leading edge/tear along a batten (about 80cm in all) done for $70 inc freight to the south coast...too easy...

Not trying to pimp his store, but credit where credit is due...i have had nothing but great service and great prices from these guys.

If a valve comes off cleanly it was 100% defectively welded and that fault would have to fall under warranty for "faulty workmanship and materials".
Some brands do honor this for the life of the kite, some don't.
I can tell you that Flexifoil, Cab, Slingy, Best do, not sure about some other brands, and then there are the ones that don't and I think it really sucks.
The bladders really don't cost that much to produce, are easy to airmail anywhere in the world, and replacing a faulty one regardless of age or ownership of the kites build great loyalty and trust with users.
Having to spend a couple of hundred for a North LE bladder on a kite that probably is not worth much more is totally heartless, and often the kites is someones favourite old ride.

Faulty welding on bladders and then no warranty grrrrrrrrr!!!!!

I can fix them, but should not have to.

Cya and

This is a common problem on a lot of kites made in the last two years. The same thing happened to my 17m Slingshot Fuel 06 last month. Slingshot/Balmoral Boards supplied a stick-on replacement straight away, no questions asked, but it still required removing and replacing the bladder to find the problem which took quite a few hours. I understand that Naish also had the same issue and recalled a number of kites to fix the bladders. Apparently the problem exists because the material used by the manufacturers for the dump valve is a different material from all the other valves and does not bond to the bladder with heat like all the others. There was no glue used, just heat. Because of the different melting tempertature the valve didn't actually melt enough to bond to the bladder. After time, it just comes off. Mine just came off in my hand when I took the bladder out. I suspect we'll see this start to happen with all the kites of this vintage as they age a bit. Not something you want to happen when you are 2km out from shore.

Thanks guys for all your suggestions. Robbo, that makes sense, it would explain why the valve came off so cleanly and without any traces of glue. Seems like this is a much more common problem than I thought.

When it happened to the first kite I tried to glue the valve back on but couldn't get it airtight. The kite doctor said that he couldn't fix it either, so I bought a new bladder. Not much change out of $200 I don't want to do that again.

I'll try my retailer again, failing that I will probably follow the suggestion of just patching over the hole left behind as I can easily live without the dump valve.

i had the same problem with a few of my naish kites (not on the tip of course)
but i just used some stormsure on it, it worked really well cos usually around the valves is a ridge type thingy which helps hold it
