Hi,

I'm struggling to elimitate water ballast leaks in a LS-7 after it has

I assume the valves are the same as in LS6c (and not available as spare

Here is a picture of the valve https://goo.gl/photos/CvYt9SPy9efS8QR56

I couldn't find a way to dissasemble the valve to be able to inspect or

Any idea how to fix the leak? Advice would be greatly appreciated,
thanks!

No it cant be disassembled, Its been chemically welded , it would have to
be cut open.
