How to Build a Vertical Item Sorter with Copper Hoppers

Assembling the Hopper Tower

Copper Hoppers possess unique routing logic that allows you to construct compact vertical item sorters without using redstone dust or repeaters.

1. Place a vertical column of Copper Hoppers, pointing each into adjacent storage containers or straight down into each other depending on your layout.

2. Open each hopper in the tower and place the designated item types into their slots. You can assign up to 5 item types per tier.

3. Make sure each level is configured for the specific items you want diverted into that tier's storage.

Taking Advantage of Pull Priority

The sorting mechanic relies on a built-in priority system designed specifically for vertical stacking:

• When Copper Hoppers are stacked vertically, the lower Copper Hopper will actively pull matching items before the upper Copper Hopper pushes them.
• As items enter the top of the stack, they pass downward until they hit a tier with a matching filter.
• Because the lower hopper takes priority over the push action of the one above it, your items are neatly sorted at their intended floor without skipping levels.
