Eric,

Thanks for responding. Unfortunately, my system appears to be different.
Basically, I have a cable (similar to a bicycle brake cable) that connects
to a thin rod which runs out the fuselage into the wing root. In the wing
root, this rod is connected to a metal arm. The axle of this arm runs
into a plastic box.

Inside the box I have no idea.

However, through some magical system, this box converts the linear motion
of the rod into a linear motion of the plug that seals the drain port.

I suspect that there shouldn't be much more than a spring inside the box,
and of course the drain plug assembly, but I guess I'll find out once I
open it!

John,

Thanks. Actually, I think the previous owner may have already used
the
"vaseline trick", maybe too many times. I appear to have a
semi-fossilized covering of what appears to be a vaseline/dirt
mixture.
I
think this is actually what may be gumming up the works. However,
cleaning it from the outside hasn't proven easy.

Well, if nobody else chimes in, I guess I dig in and hope for the
best!
I'll certainly post again with results.

DG does sell a valve rebuild kit, which, as I remember, consists of a
replacement spring, O-ring, and a few other random parts. This did
the job when one of my DG-600 valves started leaking. I didn't do it
myself, so I can't help you there, and you'll likely have to pay the
DG tax to get hold of the kit...

Hi Stefan,

Do you have a waterballast system like this:

I changed the spring without any problems. It's easy to do.
The size of the spring isn't really that critical, mine comes from a
friends "collection".
You might find one a regular hardware shop.
I made a photoshoot of the whole operation.
Just let me know if you need more details.

Best Regards,
Eric
