In the Resevoir there is a door in the left corner of the room that leads to a Storage Room. Inside the Storage Room there are a number of items on the wall and floor in this room. Vacuum up the items then movie the mop bucket using your Plunger. Moving the mop bucket reveals a pipe. Send Gooigi through the pipe then move the box by the chest to reveal another pipe. Go through that pipe then have Luigi turn the valve to shut off the water. Walk left to grab the Red Gem.

Note: Need to reach 12F before you can access this ghost.

When you reach floor 12 of the hotel you will be prompted to rescue Toad from the Boilerworks. To do this you will head through the Old Reservoir.
