Have tried a few kite shops but no luck. I need a replacement dump valve , one I can stick on over the bladder , it's for a 17m xr2 .
I think the bridle snagged it and ripped the top off it.
Did you try gokite.com.au/ ???
They are in Victoria corekites.com/us/store-locator
If you don't have any luck contact Core directly, they are amazing with warranties and customers service. international@corekites.com
I'm unsure why you need a Core dealer. Wouldn't any stick on dumps valve work? Ie ustick or kitefix. That being said my last core was the GT, so I don't know what they're like now.
Give Kitepower Queensland a call. They usually have all the Core spares in stock or could certainly help you out.
