Skimmer Problem...Please help.

[GreenSpottedPuffer]

So I had my skimmer running but turned it off today temporarily. Now when I turn it back on, its not working right. Its a PM Bullet 2 (beckett style). The problem is that when I turn the pump on, instead on the air intake for the beckett taking in air, it sprays out water!!! A LOT of water. Now all over my living room floor . Anyways, I have no idea why this is happening. I have never used a beackett style skimmer until now, so I do not know much about them. I had only ever set up the skimmer the first time a few days ago and it worked great. This is the first time I shut it off and tried to start it again and it was a disaster. Any help would be really appreciated. I bet this is something really simple that I just do not know
