Water Extractor

The Water Extractor is a building used to pump Water out of water bodies. It has one Pipeline output with recommended head lift of 10 meters.

Construction

 * The building hitbox is about 20 m x 19.5 m, however the space required to place it down is 25 m x 25 m. Thus, it is recommended to build the Water Extractor first, then build the Foundations (if desired) around it.
 * It cannot be snapped to Foundations (or any other building), regardless if the Foundation is built above water or underwater.
 * Sometimes, it can be difficult to place the Water Extractor down due to the depth of the water and the view angle. It is advised to stand on higher elevation such as on a Lookout Tower or ladders before building the Extractors.

Water depth

 * Water Extractors must be built on deep water. When building it, a warning will display if the target water is too shallow. Rivers are usually considered shallow water.
 * Water Extractors need a vertical clearance of at least 9 meters below the water surface. This refers to man-made buildings only. For example, if a Foundation is located 9 meters below the water level, an extractor can then be build above it.
 * There are exceptions: as the deep water area classified by the internal game code does not totally match the terrain appearance, there are some areas where Water Extractor cannot be built on them, in which case one must find another water source. However, there are some areas where you can build water extractors despite possessing an inadequate depth of water, or no water at all.
 * There is a work around with underwater Stackable Conveyor Pole: see below.

List of prohibited areas

 * West of the Oil Islands coast.
 * South-East of the Swamp.

Snapping

 * While staying above ground, it can be difficult to align Water Extractors as there is no snapping points.
 * If one desires the Water Extractor to snap to something, the following method can be applied. Please note: A Jetpack is required.
 * Build a stack of Stackable Conveyor Pole underwater, preferably on an underwater Foundation at least 11 meters deep, up to the water surface, then climb down the ladder to the bottom of the body of water. Tap slowly to avoid swimming away.
 * Remove 1 or 2 Stackable Conveyor Pole from the top and aim the hologram of the Water Extractor at the water surface. A point 3.75 meters away from the center of the Water Extractor will be snapped to the center point. This is 0.5 meters from the side surface of the ladder, or 1.5 meters from the center of the ladder. Refer to the diagram.
 * If you leave the ladder while in this state, you won't be floating in the water and can die of fall damage. Use the Jetpack to re-surface. If you are already on the waterbed, pressing the jump key will also return you to the swimming state.
 * The Water Extractor pipe outlet is not at its center. It is offset by 0.75 meters to the left, so it won't align with the 1-meter grids on Foundations.

Head lift
The Water Extractor has a recommended head lift of 10 meters. It can still output water up to 12 meters maximum head lift, with slightly reduced flow. As it lacks a head lift gauge, the only way to check its head lift is by interacting with Pipelines to check if the water is flowing.

Overclocking
Water Extractors can be overclocked by using Power Shards. At 250%, a Water Extractor produces exactly as much flow as a Pipeline can transport.

History

 * Patch 0.3.4.4: Now should be place-able again in water with enough depth
 * Patch 0.3.4.3: Now should be place-able again in more locations (there are still some issues)
 * Patch 0.3.4.0: This patch made Water Extractors no longer snap to the water surface, making them impossible to place.
 * Patch 0.3.3.0: The fluid display now shows the correct amount
 * Patch 0.3.2.1: Now should no longer be upgradable to Geothermal Generators
 * Patch 0.3.2.0: Now should no longer be disconnected from water on load when the water volume has been replaced
 * Patch 0.3.0.1: Fixed some water volumes on the map causing the Water Extractor to stop outputting. Affected Water Extractors will have to be rebuilt
 * Patch 0.3: Introduced
