It leaked before my neck got in the water. Felt it at he waist. I first noticed it when my inflator valve went underwater. Maybe that's the culprit?
I def heard a his from somewhere as I got in the pool other then from my shoulder valve.
That's an idea. I don't think it's like a small hole though.
Take the inflator valve apart. Note if it's screwed together tightly when you unscrew it.
Make sure any gasket that is supposed to be there is in fact there.
Put it back together and make sure it's screwed together tightly.
Try again.
