![Image](https://forums.factorio.com/images/ext/d248597607c6a9af61062c8b0cb96890.jpg)
The problem is that the plant doesnt want to make sulfur. If I switch for example to plastic the petroleum gets pumped in. If I switch to sulfur acid, the water gets pumped in, but if I set it to sulfur nothing gets pumped in and thus sulfur is not being made. Any suggestions?
