Thanks for the replies. Sounds like that should be the way to go. I was so looking forward to not carrying around a small Phillips all day every day but oh well. I'll quit whining and just use it the way it was intended. I was convinced I broke the dam somehow but after hearing this I realized there are really only 2 places it could be leaking from. The O-ring and the fill hole. No way it's coming down through the air hole. Not when I only filled it up a little bit.
Happy Holidays all. Thanks again. Sometimes it just takes hearing it from someone else to make your mind up.
Fill it from the top!
No need to carry a screwdriver.
