Drainage Control Hall

The Drainage Control Hall is a location in Luigi's Mansion 3. It is found in the Boilerworks on the second basement floor of The Last Resort, located east of the Old Reservoir and west of the Drainage Control.

The Drainage Control Hall is only accessed when Luigi visits Boilerworks again to rescue Toad. Luigi can Strobulb the green light to open the hatches from above. The door is missing a handle, so Luigi must launch Toad above the platforms to obtain the handle to proceed to the Old Reservoir.
