If you can access the hose and want to try the air can, make sure you seal up the space between the drain hose and air can hose. Nothing permanent, just to keep the air from coming back at you, duct tape perhaps.
If you have anything long, thin and flexible, use that to unclog the drain. Question is, how long is the drain, what's it made of, and can you access the end the water should be coming from (outside somewhere maybe)? I've always had good luck with a coathanger for these things, or if you can find one of these at a dollar store.
