Liquiduct

The Liquiduct is a pipe that will transport liquids without the use of a wooden pipe and engine. It does still require a redstone signal to work. A wrench can be used on the pipe where it connects to a liquid source to determine the direction of flow.

When you + "Right-Click" a conduit with the Wrench or Crescent Hammer it will dismantle the pipe in order to be picked up as the pipes are very sturdy otherwise.
