I've found it VERY hard to flood an area in this game. The water physics don't work like that. You'll probably fill the deepest-down room in about 2 blocks of lava/water, with a stream of water/lava leading back to the entry point. If you want to flood an area, you'll have to place water/lava-generationg blocks in the area manually. The bucket SHOULD let you pick up and carry generator blocks.
