“A Job for a Plumber” is a side mission in Luigi’s Mansion 3 (the latest mainline entry as of 2024), not the original GameCube title. It appears during your exploration of The Last Resort, the haunted hotel where most of the game takes place. This mission becomes available after you’ve progressed through several floors and unlocked the Plumbing Room—typically around Floor B2 (The Basement).
💡 Fun Fact: According to Nintendo’s official sales data, Luigi’s Mansion 3 has sold over 14 million copies worldwide since its 2019 release, making it one of the best-selling Nintendo Switch exclusives. Side quests like this add replay value and depth to the experience.
Where Do You Find the “A Job for a Plumber” Mission?
You’ll encounter this mission after meeting Gooigi (Luigi’s gooey doppelgänger) and gaining access to the basement levels. Specifically:
Complete the main story up to Floor 5 to unlock elevator access to lower floors.
Head to Floor B2—the Maintenance/Plumbing area.
Look for a clogged pipe spewing green sludge near the eastern corridor.
Interact with it to trigger the mission: “A Job for a Plumber.”
🔍 Pro Tip: Make sure you’ve upgraded your Poltergust G-00 with the Suction Shot ability—it’s essential for this mission.
Step-by-Step Walkthrough: How to Complete “A Job for a Plumber”
This mission requires you to unclog three major pipes using Gooigi and Luigi in tandem. Here’s exactly how to do it:
Step 1: Clear the First Pipe (East Wing)
Use Gooigi to slip through the small grate beside the clogged pipe.
Inside, you’ll find a valve. Have Gooigi turn it clockwise.
Switch back to Luigi and use the Poltergust to suck out the sludge. Hold the ZR button for 3–4 seconds until the pipe gurgles clean.
Step 2: Access the Central Junction (Requires Suction Shot)
Return to the main hallway and locate a metal panel on the floor (shiny, slightly raised).
Use the Suction Shot (press Y, then aim and release) to rip it open.
Drop down into the pipe network below.
Step 3: Navigate the Pipe Maze with Gooigi
In the maze, you’ll face mini ghosts (Slammers). Use Gooigi to distract them while Luigi sneaks past.
Find the second valve—it’s behind a water-damaged wall. Blast it with Strobulb flash (press R) to reveal it.
Turn the valve, then return upstairs.
Step 4: Final Pipe – Teamwork Challenge
The last pipe is blocked by a ghost-infested wrench.
Use Luigi to stun the ghost with flashlight, then immediately switch to Gooigi to grab the wrench through a narrow gap.
Place the wrench on the pipe nut and rotate it counter-clockwise.
Once all three pipes are clear, a golden treasure chest appears containing 1,000G and a rare gem.
⏱️ Time-Saver: Most players complete this mission in 6–8 minutes once they know the steps. First-timers often take 15+ minutes due to confusion over Gooigi mechanics.
