The bathtub in our second floor drains slower that molasses. The only thing I've really tried to access it with is this plasic strip with barb hooks on it that I have used successfully in the past to clear two teenage girls hair from the drain. I can snake this thing down quite a way and am not getting anything. I've also tried plunging it some with no luck. I'm pretty sure it's just a hair clog somewhere but I don't have a clue as to how to clear it. It seems like the only thing I can remove is the little cover on the top of the drain. This is what I remove to snake the strip down.
