Valves and fluid levels
Valves change fluid paths and levels. Storage capacity and flow rate make opening order consequential.
The player's decision
Fill the upper reservoir first or send limited water straight to the destination?
Original scenario
Original setup: one tank feeds a target and a drain. Opening both wastes water; close the drain to reach the target level.
Start with this prototype
Build three tanks, two valves and finite initial water using integer flow. Show transfers and overflow each step. Reach the level target; offer pause/step without particle fluid simulation.
Change one variable
Vary flow rate and check whether decisions become unreadably fast reactions.
What to observe in a playtest
Does initial water equal remaining, delivered and lost amounts? Do closed valves stop flow?

Original analysis · version 1
Common pitfall
Two outlets independently spending the same old water can duplicate fluid or create negative stock.
Observations and sources
Cases refer to public documentation. Developers and community wikis are credited separately; document review is not a claim of hands-on testing.
- Factorio
Pumps act as directional, condition-controlled valves, connecting flow paths with switching logic.

The developer update discusses fill-valve target levels and wave handling for dams and floodgates.
