Pumps

Inlet and Outlet Pumps are mechanisms used to transport liquids (water, lava, and honey), without having to construct pathways through blocks or rely on gravity. Instead, an Inlet and Outlet Pump need only be connected to each other with Wires and activated, which transfers fluid from the Inlet to the Outlet. Each activation transfers up to four tiles of liquid. For continuous automated pumping, a timer can be used.

Despite its appearance as a pipe that takes in liquid from beside it, an Inlet Pump must be submerged in liquid, as it removes liquid that lies directly over its graphic, and does so equally from all of its 2×2 tile space. Similarly, an Outlet Pump spawns liquid directly over its graphic, and does so equally over all of its 2×2 tile space.

Tips

 * In versions, The Outlet Pump's ability to produce more liquid than an Input Pump takes in can be exploited in multiple ways:
 * Tanks of liquid can be created by repeatedly sending liquids through a pump system. Only enough liquid to submerge the Inlet Pump is required, and any extra liquid produced from the Outlet Pump can be used to fill the tank, providing infinite liquid as long as a separate tank for actually producing the duplicate liquid is maintained.
 * Using this gimmick, Obsidian/Crispy Honey Blocks/Honey Blocks can be mass-produced through the duplicated liquids.
 * Ponds of water, such as fishing ponds, can easily be created using only a small amount of liquid.
 * Lava falls can be made by using pumps, which can be used as an NPC-killing device or a means of protecting one's house from enemies.
 * While of little use compared to lava falls, aesthetic waterfalls can also be made using Pumps.
 * In item form, Pumps have a white rarity and will be destroyed when submerged in lava. While this is not an issue with other liquids, take care to ensure that the pump never becomes unseated while any lava is present, such as by mining the Inlet, or by placing the outlet on a platform (as lava removes all platforms except obsidian or stone). First drain the lava or convert it to solid blocks before attempting to remove the pump.

Trivia

 * Both pumps' tool-tips wrongly describe that they are used to send or receive only water, whereas they send and receive any liquid.
