I need to replace the valves on my old Avon Redcrest. Whats the trick to loosening the big nut that holds the valve in place? I can get a big wrench on the hex nut, but don't have any way to get a good hold on the surrounding fabric
to apply the opposite force required.
Do I need three helpers to stand on the fabric
while I use the wrench?
This dinghy is about 30 years old but only used lightly for a few years early on. It is in great shape except after pumping it up it the valve leaks
so fast (I do have the stem rotated to the closed position during inflation) I can't get the outer cap on fast enough to avoid loosing a lot of pressure.
