Sandustry Water Guide: Circulation, Loss, and Early Game Stability
Water enables transformation, but it stops feeling like a simple resource the moment circulation matters. Every loop introduces loss, routing pressure, and the need to recover water instead of spending it once. How you close that loop decides whether early processing stays stable.

How Water Moves Through a Base
Water travels as a closed loop from Pipe to machine and back, bleeding a little wherever routing is uneven or a seam leaks. Unstable output usually traces back to one pressure point; fixing that restores the whole chain.
Treat water as a loop
Water is reused, not spent: a loop returns whatever the machine does not consume and only needs a top-up for true losses. Designing that return path is what turns a shaky setup into a calm one.
Spot hidden loss early
A small leak in routing quietly compounds into the bottleneck behind several unrelated shortfalls, because each downstream stage assumes the water arrived. It shows up earliest in the fragile opening loop.
Follow the heat chain
Water and Steam are the same loop at different temperatures: heat water and it becomes Steam, cool Steam back down and it condenses into Water again.
Move water with a Pipe
Pipes, Pumps, and Liquid Vents carry Water across the map, and they all share one caveat: Lava is the single liquid they refuse to move.
