I am wondering if the oceans at either end of the map are infinite. I want to use one as my primary source of water by using 2 pumps and an insanely long wire (using a sky bridge) to pump water back to my base, while at the same time using it for my Obsidian Farm. I'd rather not have to worry about setting up a second water source in the middle of Hardcore Mode.
No, it is not infinite, see the wiki:
- Players may attempt to drain the ocean by tunneling down to the Underworld, where water evaporates. The Ocean is in fact drainable this way, and this method will allow the player to go back to the Ocean floor and easily pick up all the Coral without worry of suffocating. However, no Sharks will spawn once the Ocean is drained, and previously-spawned Sharks will have vanished. Therefore, draining will not allow a player to obtain Shark Fins and the Diving Helmet.
- Another way of draining the ocean is by making an air pocket, empty a bucket of lava in it and place an object that can't be destroyed by lava in the lava. After that allow the water to flow into the lava. The object will prevent obsidian from being generated, causing all the water to disappear.
- If your house is over 2000 blocks (4000 feet) you would need multiple wire networks to move the water, as a single wire 'network' can only consist of 2000 wire.
- Just use an infinite water source if you need alot of water.
