Why the pump matters
The old church door stays shut until Elymere’s pumphouse restores power. That is the published goal of this stretch, and it is also the trigger for Vos to hand over the Village Supplies box. The box is not a store redeem code. The game has no redeem-code system.
- The door at the back of the Wash is locked. Go to the lower floor and take the time crystal.
- Move left and sync the glaive. Take the blade with you when you leave the sync point.
- Go up and left. Use the glaive to open the door on the left. The key is on the right; a dive picks it up.
- At the pipe panel, read the engineering log, match the on-screen diagram, and watch the flow indicator.
- When power returns, the old church door opens. Talk to Vos for the supplies box.
What is not confirmed
I am not printing a dial setting. The three public write-ups do not agree on the exact facing, and none of them is a developer post. If your panel does not match a number you saw elsewhere, trust the diagram in the room and the flow indicator, then read the log again.
Refuge has a 20-second timed door on the way in from the Wash. If you miss it, a developer reply told players to look at the hole in the middle of town. Players confirmed that hint worked. That hole is the bypass, not a second pump puzzle.

What is the Lake Pumphouse pipe solution?
Read the engineering log, align the panel with the diagram on screen, and watch the flow indicator. This page does not print a dial number, because published numbers conflict.
