Draynor manor top floor
climb the stairs
The pressure gauge is found in the fountain which is somewhere around the manor, but not outside the manor gates. If you try to search the fountain ( right click, search ) you will notice that there is a school of vicious piranhas in there and it will cause you damage, but you will find some fish food and poison in the manor. Use the poison on the fish food, and it will become poison fish food. Feed it to the fishes and they will die and then you can get the gauge out safely.To see more information on the quest, Ernest the Chicken, go to the link below.
