I've got this entire oil line setup and my first chemical factories set to produce plastic; they work fine.
Now I've setup another one to make sulfur (for a battery chain), but it won't accept any input!
To be clear, both Petroleum Gas and Water are piped to separate inputs, yet NO items show up in it's inventory.

I just bought this game and this is the first non-ui problem that I've run into.
Will some knowledgeable people please take a look?
