Sandustry Troubleshooting: Filters and Factory Problems
Fix common Sandustry factory problems with focused guides for Wet Sand filters, Water backups, blocked Haulers, and unstable material lanes.
When a Sandustry line fails, isolate one material lane before rebuilding the whole factory. The most useful troubleshooting step is usually a small test sample that shows where a pixel, liquid, gas, or Hauler stops moving.
Material separation
Let Wet Sand through but stop Water with an isolated filter lane before reconnecting the Shaker. The infinite water guide explains why water routing should stay separate from output storage.
Hauler routes
Remove or stop Haulers only after checking their destination and nearby cargo. A route change that leaves material without a destination can create a second blockage.
Before escalating
Test one input, one transformation, and one output at a time. If the behavior changed after a patch, note the game version in your report and compare it with the current in-game prompts.
