Replacement Valve for Supply Depot.

[Digital_Ladd]

While I was exploring, I broke into a building called the Workshop. I found a Valve with a note saying to take the replacment valve to the Supply Depot near the Docks. Since Dishonored has no in-game map what-so-ever, I have no idea where to take this valve.

It's the room with a dead overseer lying inside(use your dark vision) or you could say it's the last house before you reaching the dock

I had this problem too, initially. Take the valve to the far back right corner of the map (as if going to leave). You'll see a building with two boarded up windows and a body inside. Attach the valva on the right of this building (if you face the water).

Nice, I know exactly where that is. Thanks!
