The first and easiest time you can find and solve an inspection clue is during the "The Driver's Seat" case at the Traffic Desk. At one point during the case, you are required to travel to the Black residence. Once you arrive, go along the right, outside part of the house and you will come across a water heater. Press
to interact with it and simply assemble the pipes. As soon as the last pipe is in its correct place, the achievement will unlock.
