In this page you can find a detailed description of "Call the Plumber" achievement that you can unlock in Get Even. You get this trophy for sabotaging sanitary in order to distract ADS guards.
You can get this trophy during "Job for Robert Ramsey" memory that is reserved to Black. This level takes place in ADS and your goal is to steal a CornerGun. To be more precise, it is the beginning part of the memory in which you are travelling through severs in order to reach an underground parking.
Continue walking until you reach the room with a closed gate, hot gas and six red valves presented in the picture. Here, you must solve the valves puzzle (don't choose the option in which you must destroy the padlock because you won't get the achievement!).
The solution for that puzzle is generated randomly but despite of that completing it is not that difficult:
- Approach each of the valves and examine them.
- Your goal is to have all valves turned to the right. If that happened with the valve that you chose then, after turning it, you must leave it.
- If a valve turned left then you must interact with it again and turn it right (it will go back to its default state).
After turning all valves the hot gas will disappear. Crouch and proceed further.
You won't get this trophy right after you solve the puzzle but a little bit later. You must continue your journey through the building and reach the place where you have to use the elevator that is located on the floor next to the lobby. Enter the elevator and go up to the twelfth floor. Leave it and get closer to the guards on the left. The achievement is unlocked during the conversation.
