Emerald Waterproof Pipes are a fairly recent addtion to Buildcraft 3. An Emerald Waterproof Pipe is crafted with a regular Emerald Pipe with Pipe Waterproof placed above it in a Crafting Table.
Purpose of the Emerald Waterproof pipeEdit
Emerald Waterproof Pipes serve the same purpose as Wooden Waterproof Pipes, and can extract liquid from a container (ex: water from a tank) with the use of Redstone Engines. The Emerald Waterproof Pipe, however, can extract liquid up to and around 2 times faster then a Wooden Waterproof Pipe. They do require the use of an engine with an MJ output higher than that of a Redstone Engine.
