If your looking to remove large amounts of water from a single player world, there's no quick way. To remove it completely, the best would be to get some lava, and dupe it with pumps (though not sure if this still works for 1.2), but this takes time to set up and if you flooded your house, you'll want to drain it to elsewhere first, as this can potentially ruin your house even worse then lava. The quickest way would be to use buckets, taking them one at a time, then throwing them away. However, this is quite expensive. However, if you want to take a long way, you could try taking as many water buckets as you can, taking the water out, then go to another world and dump it out there.
