|/obj/machinery/plumbing||Basic plumbing object.
It doesn't really hold anything special, YET.
Objects that are plumbing but not a subtype are as of writing liquid pumps and the reagent_dispenser tank
Also please note that the plumbing component is toggled on and off by the component using a signal from default_unfasten_wrench, so dont worry about it|
|/obj/machinery/plumbing/input||We can empty beakers in here and everything|
|/obj/machinery/plumbing/output||We can fill beakers in here and everything. we dont inheret from input because it has nothing that we need|
|/obj/machinery/plumbing/layer_manifold||Layer manifold machine that connects a bunch of layers|
