Ranged Pumps — FAQ

Troubleshooting

The pump is idle but there is fluid below it. - Check that the column between the pump and the fluid is clear of full solid blocks. A single opaque block in the path stops the scan. - Make sure the pump is not receiving a redstone signal (signal = pause). - Confirm the pump range in the config is large enough to reach the fluid from the pump's height.

Fluid stops flowing after a while. - The source was finite and is now empty. Either fill it again or point the pump at an infinite source (ocean, lava lake in a nether biome). - The output pipe or tank is full. Check your storage system.

The pump appears to work but no fluid arrives in my tank. - Verify the pipe/tank is placed against a face of the pump that can output (sides or bottom). - Some mods require the tank to be set to "import" or "pull" mode — check the tank's own UI.

Performance concern with many pumps. - Each pump runs a downward scan on every operation. Increase pump_speed in config to reduce tick load when running many pumps simultaneously.
