Agreed. Did you think to check if the inner valve body was screwed tightly into the outer valve stem?
And it's a stupid question, I know, but was the little screw on the inner valve body screwed tightly? You'd think that would be self-evident, but at a ride today I was airing up some tires for someone else and theirs were not at all tightly screwed in.
