DG-300 water bag valve Q.

[[email protected]]

Okay, the valves at the wing root for the ballast bags have lost there
"spring" . In other words, they wont stay shut. I can pull on the
valve push rod slightly and get a good seal, but it leaks when I
release it. Is there a spring inside that push rod boot, that can be
adjusted/replaced, or is the boot itself adjustable to provide the
required tension on the seal? any help is always appreciated... GAP.

They can be replaced. If thet are anything like mine (DG-600 1989)
they were steel springs and they rusted/rotted out. Replace them with
stainless steel springs. Industrial hardware store.
