A small mod that adds special "sinks" that consume any fluid fed to them, and track how much they get. This can be useful for testing pipeline/pump throughput.

It also includes a practically-infinite water source (it produces water faster than anything in the base game can accept it, anyway).

Disclaimers: this stuff is not balanced or pretty, and is designed for testing only, not for use in day-to-day gameplay. This is also a very early effort, and has not been tested in multiplayer games. It is also not designed to be particularly UPS-friendly if you build a whole bunch of stuff from the mod.
