Respuesta rápida

The riser valve is a red wheel on the blue pipes in the corridor. On Day 5 its hint reads "A seized red wheel valve on the risers - it needs a wrench." Carry the Adjustable Wrench to it and turn the wheel, and by Day 6 the message is "The riser valve is open - the north tank feeds the taps upstairs." The Day 6 guide note is called "The north tank reserve".

How to open it

  • Pick up the Adjustable Wrench from the latched toolbox (Day 2).
  • Find the riser pipes with the red wheel and gauge (the footage shows them on Day 5 and again on Day 6).
  • With the wrench in hand, turn the wheel; a round turn arrow shows around the pipe.
  • Read the message: "The riser valve is open - the north tank feeds the taps upstairs."

Why open it

On Day 2 the objective is "Fill every container before the taps stop", so the taps run out early in the run. Once the riser valve is open, the game says the north tank feeds the taps upstairs. The water-use side (filling, treating, rain) is on the food and water page.

The later days mention the same valve: Day 31 to 32 sends you to the management office on floor 27 to open the north tank's riser valve (a wrench) before cutting a chain on the fire doors. See the later days page.

Tips

  • Don't skip the wrench: the valve is seized and does nothing without it.
  • Do it on a quiet day. Day 5 and Day 6 were "Inspect supplies" and "Clouds are building" days in this run.
  • Put out containers on the balcony brackets on Day 6; the objective says rain will fill them.
