Help me with the [OMFG SPOILER]

[Lorkas]

Alright so I just entered the area where you drain the water off. I've succesfully done it so I need to find an antidote for the poisonous gas, but there's a room where you have to collect these pipes and put them on a wall. I've checked every corner there is, and shit the last one just doesn't exist. When I put some of them on, I heard The Voice say "Daniel, what are you doing?". Also those two metal pressure towers are working OK now.

So guys, give me a few tips but don't make it too obvious please. Hell, I don't want this amazing game to get spoiled. I closed my eyes when I opened this forum section.
