Stumped on the Pool achievement. I'm at the pool area, I got the instructions but I do not know how to progress after. I've been trying to look for a Valve or Spigot which is supposedly on the wall to the right of the plant. However, I don't see one! When I click "E" around the area, nothing much happens besides the usual dialog. Help! I love the art and overall storyline of the game, and I'd love to progress but I'm having trouble doing so.
