Sandustry Water Sources and Pipe Fixes
Water is both an input and a moving material. Contain it, meter reactions and understand how heat changes its route.
Quick answer
What to do
Use a contained pool and a controlled outlet. One Water plus one Sand becomes two Wet Sand. Heating Water creates Steam that rises; Steam reaching the sky returns as rain. Water can also slip through diagonal corner gaps.
How do I get more Water in Sandustry?
Use lakes, underground deposits or melted Ice early on. The official Water page also documents making Snow with a Cryoblaster, heating it into Steam and catching the rain. The Hydro Sponge upgrade lets the Grabber move Water by hand.
For passive production, look for Lumlings. Rain from boiling existing Water is recovery: the Steam entry explains that apparent extra rain can come from a buffer of previously evaporated Water. Do not assume boiling the same pool creates new Water indefinitely.
Why did my Lumling stop making Water?
Lumlings produce Water and can be captured and released with a Corraller. They need open space: surrounding Water, another liquid or gas can stop production. Drain the collection area and keep Steam away from the creature before adding more Lumlings.
How much space should I check around a stopped Lumling?
The official wiki describes Water within a 4×4 area around a Lumling as pausing its production timer. It also says submerged Lumlings and those floating in Steam or another gas do not produce Water.
As a diagnostic sequence, drain the nearby Water, clear the liquid or gas around one Lumling, then observe whether it resumes before adding more creatures. This follows the documented obstruction rules; it is not a tested maximum-output layout.
Lumling wiki revision 1370, reviewed October 9, 2026. The page does not identify a game build, so the clearance rule is a wiki-based check rather than a v0.5.7 gameplay measurement.
Update #3 adds a temporary capability boost when you move over a critter to pet it. The patch does not state a universal water-per-minute rate, so size collection around the output you observe.
Contain the reservoir
Water spreads until it forms a level pool, while unsettled droplets can evaporate after the documented delay. Solid walls block direct flow, but Water can slip through the meeting point of two block corners. Close diagonal gaps and leave enough depth that a small feed does not expose the whole reservoir.
Meter the Wet Sand reaction
The reaction consumes one Water and one Sand and creates two Wet Sand. A wide uncontrolled contact surface can convert a large amount at once. Use a narrow gate, watch the product leave and keep the Water source physically separate from the Shaker output area.
Use Steam as upward Water transport
Heating Water or Snow produces Steam. It rises until blocked and pools under ceilings. Steam that reaches the sky falls as rain. Build an open vertical path and a collection basin where you want the returning Water; leave enough catch area for rain that spreads sideways.
How do I connect or cross Pipes in v0.5.7?
- Extend a network deliberately. Start or end the new Pipe run on an existing Pipe tile. Building beside another Pipe no longer connects it automatically.
- Cross a line with a Pipe Bridge. Building across an existing Pipe line now creates a bridge. The old rule that every crossing joins the networks no longer applies.
- Check the overlay before opening the feed. It shows the color of the last liquid piped through that route. Use it to trace the network, then inspect the receiving Vent; the color is not proof of what is flowing right now.
These changes shipped in Update #4 on September 14. The developer notes that bridge construction can still have quirks. For selecting or copying a whole liquid line, use the Pipes Mode and Alt+C instructions.
How do Pumps, Pipes and Liquid Vents work?
The Fluids research unlock contains Pipe, Pump and Liquid Vent. A Pump takes in non-lava liquid touching it; a continuous Pipe network carries it to a Liquid Vent. Pipes occupy a separate layer and can overlap placed blocks.
One network can connect multiple Pumps and Vents, but different liquids share the same system and can reach every connected output. Use separate networks when the destination must receive one liquid type.
Capacity check: the current Pump and Liquid Vent entries give a maximum of 16 pixels per tick for a fully submerged Pump and 4 per Vent. One full-capacity Pump can supply up to four clear Vents; this is not a guaranteed rate when intake or exits are obstructed.
Why is my Pump or Liquid Vent not working?
| Symptom | Verified check | Action |
|---|---|---|
| Pump moves no liquid | Non-liquid pixels can block its intake. | Inspect and clear the material touching the Pump. |
| Vent stops as the pool rises | A Vent stops when three-quarters submerged. | Lower the receiving pool and clear the outlet. |
| Wrong liquid appears | Connected outputs share liquid; v0.5.7 crossings can use Pipe Bridges. | Trace the actual connections and last-liquid overlay; split any unwanted shared network. |
| New Pipe beside an old one carries nothing | Adjacent placement no longer auto-connects in v0.5.7. | Start or end the new run on an existing Pipe tile. |
| Pipe cannot be removed | Pipes have their own editing layer. | Select the Pipe tool and right-click the Pipe, as the current Wiki instructions describe. |
