How to solve the pipe puzzle
The pipe puzzle requires three pipes that can be found in different rooms of the Control Room. Here are the steps to solve the puzzle:
Enter the first door on your right. You should see a U-shaped pipe with a small blue glow right in the middle of the floor; pick up this pipe and throw it back into the hallway. You'll need it for later. In the back right corner of this room, you'll also find a Tinderbox sitting on a stack of crates.
Enter the room directly across the hallway. The right corner closest to the door has another U-shaped pipe; again, pick it up and throw it into the hallway. On the left side of the room, you'll also find a Tinderbox sitting on a large crate with a lit candle.
The purpose of this room is to balance the hanging sand bags using the rotary handles on the left (you essentially have to match the configuration that the prior room used). However, the game makes it easier for you: all you have to do is rotate the handles until you hear a click. Once all three are aligned, you'll hear steam start flowing through the pipes in the room.
Exit this room and enter the door on your left. Note that you have to use a crank-wheel to open this door and the door will slowly close down. Make sure to bring the pipes with you into this room as well.
Once you and the pipes are inside, keep them in the middle of the room, as you'll be collecting more. First, head to the room on the right. You'll find another pipe at the bottom of the stairs; throw this pipe back with the others. Facing up the stairs, you can find an Oil along the left side on the ground. If you go to the right side, you can find a Tinderbox and [the Machine note] on a small table.
Now, go into the room on the other side of the hall. Once down the stairs, take a right and grab [the Wooden Crank] on
