===[[File:Plunger.png]] Plunger ===
All of the basic plumbing machinery can be plungered to empty their contents on the floor; simply use the plunger on them to flush them clean. Can be very useful if you got some machines that need to be emptied quickly, or for solving clogs. Can be printed in the medical and engineering lathe.

You can use the plunger in-hand to toggle to layer mode. You can now select a layer with alt and turn machinery to that layer.
