Crates, barrels and NPCs that drop the Water Pump, most likely first
| From | Chance | Amount |
|---|---|---|
 Locked Crate | 1.3% | 1 to 2 |
 Elite Crate | 0.78% | 1 to 3 |
| Scientist PT Boat Dry Box | 0.73% | 1 to 3 |
 Military Crate | 0.42% | 1 |
 Underwater Lab Military Crate | 0.42% | 1 |
 Wagon Military Crate | 0.42% | 1 |
Missile Silo Scientist (underground) | 0.3% | 1 |
Scientist | 0.074% | 1 |
Heavy Scientist | 0.061% | 1 |
 Treasure Box, mission reward | 1.6% | 1 to 2 |
 Gingerbread Mine Present, Christmas event only | 0.42% | 1 |
Chance is for one container opened or one NPC killed. Amount is how many it holds when it holds any.

Metal FragmentsEach swing charges the share of the cost for 50 health, rounded up to whole resources, and restores as much health as it paid for, which can be more than 50. Nothing can be repaired for 30 seconds after it takes damage.
What the Water Pump gives back in each recycler
| Recycler | Efficiency | You get |
|---|---|---|
| Red recycler | 75% | 75% Gears, 150 Metal Fragments, 187 + 50% Wood |
| Green recycler (powered) | 60% | 60% Gears, 120 Metal Fragments, 150 Wood |
| Green recycler | 50% | 50% Gears, 100 Metal Fragments, 125 Wood |
| Yellow recycler | 40% | 40% Gears, 80 Metal Fragments, 100 Wood |
The Water Pump breaks down into Gears, Metal Fragments and Wood.
A recycler takes them one at a time, so a full stack of 3 goes through in 3 cycles.
Figures are for one item in perfect condition. Each recycler’s name opens its full table at this item. “187 + 50%” means 187 every time and a 50% chance of one more, and a percentage alone is the chance of getting one.
In Rust, Water Pump is a electrical in the Electrical category (item ID #-1284169891, console shortname waterpump). In active play, it follows standard server rules for electrical gear across procedural maps. Inventory storage stacks up to 3 units per slot, and uncollected ground drops despawn after 20 minutes.
Can be placed in a water source to collect that water while powered. Can be connected to other Water entities.
Crafting Water Pump in Rust takes 25 seconds at a Workbench Level 2 once the 30 scrap blueprint node is unlocked, with all ballistics, crafting, and durability values read from the Rust game files. Shredding a spare copy at a green recycler recovers base materials at fifty percent yield (vs forty percent at safe-zone yellow units). Placed structures heal with a Hammer using raw materials from your inventory.
When choosing between Water Pump and related electrical in Rust, prioritize researching a looted or traded copy at a Research Table (30 scrap) whenever you want to skip the 300-scrap tech tree path and save 270 scrap, or unlock the tech tree branch when your group also needs the prerequisite blueprints.
| Item | Category | Stack Limit | Craft / Source | Tech Tree / Research | Green Recycler Yield |
|---|---|---|---|---|---|
| Water Pump | Electrical | 3 per slot | Workbench Level 2 | 30 node / 300 path | Not recyclable |
| Fluid Switch & Pump | Electrical | 5 per slot | Workbench Level 1 | 15 node / 210 path | Not recyclable |
| Water Wheel | Electrical | 1 per slot | Workbench Level 1 | 60 node / 75 path | Not recyclable |
| Seismic Sensor | Electrical | 10 per slot | Workbench Level 2 | 30 node / 225 path | Not recyclable |

To compare Water Pump against every item in its inventory category, browse All 83 items in Electrical, or plan prerequisite scrap paths on the The Engineering Workbench tech tree, tile by tile.
The Water Pump has 300 health once placed in Rust. It belongs to the Electrical category under numeric ID -1284169891 across 83 electrical, while F1 console command inventory.giveid -1284169891 3 spawns 3 units for testing across 83 published Electrical entries (79 with crafting blueprints).
The Water Pump is crafted at a Workbench Level 2 from 250 Wood, 200 Metal Fragments and 1 Gears, once the blueprint is learned in Rust. Smelting raw ores and looting required components from monument crates lets players queue the craft at their workbench.
The Water Pump drops from 9 container and NPC loot tables in Rust, led by Locked Crate (1.3% chance), Elite Crate (0.78% chance), and Scientist PT Boat Dry Box (0.73% chance). Each listed probability reflects a single container opened or NPC killed, and found copies can be repaired or researched at base.
The Water Pump recycles in Rust at an unpowered green recycler into a 50% chance of Gears, 100 Metal Fragments and 125 Wood. Full recycler yields apply to an undamaged copy, while partially worn gear returns proportionally fewer materials based on its remaining durability bar.
The Water Pump takes 25 seconds to craft, down to 12.5 seconds at Workbench Level 3 in Rust. It sits in the Electrical catalog with item ID -1284169891 alongside 82 related electrical, with F1 console command inventory.giveid -1284169891 3 across 83 published Electrical entries.
The Water Pump repairs in Rust once placed with a Hammer for up to 125 Wood and 113 Metal Fragments at full wear (6 swings). Hammer repairs draw materials straight from your inventory with zero maximum-health penalty, provided the placed object has not taken damage within the last 30 seconds.
Blueprint progression for Water Pump at Engineering Workbench in Rust charges 30 scrap on the target node and 300 cumulative scrap along the prerequisite branch, while direct blueprint study at a Research Table charges 30 scrap. It belongs to the Electrical category under numeric ID -1284169891 across 83 electrical.
Dropped on the ground in Rust, the Water Pump despawns after 20 minutes by default. Picking it back up into a player inventory or storing it inside a base container immediately resets that ground despawn timer, which the server scales by item rarity tier.
The Water Pump has 32-bit signed item ID -1284169891 and shortname waterpump in Rust. Server plugins, custom loot tables, Vending Machine listings, and automated Industrial Conveyor filter strings reference these two identifiers under the Electrical category (stack limit 3 units per slot).
Server administrators in Rust spawn the Water Pump in the F1 developer console with inventory.give waterpump 3 or inventory.giveid -1284169891 3 for 3 units. Both console spawn commands require administrator or moderator privileges on the server, while regular players can bind a quick-craft shortcut key instead.
