If you don't have a plug but just this valve, I bet your supposed to have a plug too.
Yes, I do have a plug also.
I like this feature for two reasons:
One - It functions perfectly and doesn't allow water back when I stop to put the plug back in. Doing this while on a plane is not something I really want to be doing.
Two - I have been known to launch the dinghy
and forget to put the plug in. By itself that is not really a big problem, but invariably I will have a dinghy full of supplies, clothes and tools that I would rather not get wet should/when I forget to put the plug in. I have forgotten it while this diaphragm was missing.
I usually remember I left it out when it is in the water and I am climbing in to back it off the trailer. Seeing my food
for the weekend floating makes for a bad start to a good weekend...
