Because the duct loosen sometimes in the wing.
And to sit 5 hours in water is not very nice.
I welded an outlet in direction wing root.
Now this does not loosen anymore.
But the PVC disformed.
The PVC you can disassemble by knocking out from above.
First loose the couternu, then take off the rin and the nut.
The only method to disassemble the vlv when the spring is broken.
But i noted too late there is PVC in.
If I would have da spinbank I could build a new one.
But I don´t have...
