STRINGS.MISC.NOTIFICATIONS.GUNKEDTOILET.MESSAGEBODY
Bionic Duplicants can dump built-up Gunk into Toilets if no other options are available. This invariably clogs the plumbing, however, and must be removed before facilities can be used by other Duplicants.
Building a Gunk Extractor from the Plumbing Tab {Hotkey/Plan5} will ensure that Bionic Duplicants can dispose of their waste appropriately.
