Use a wrench for the pipe leak
For S.O.N.A.R. pipe leaks, the useful tool identified in player commentary is the wrench. Find the leaking area, bring a wrench, and carry out the repair there before turning your attention to the water already inside the submarine. Fixing the damage and clearing the flooding are separate parts of getting the boat back under control.
In the community recording We Should Never Be Trusted With a Submarine!, the crew calls for help in the engine room, identifies the repair as a wrench job, finds a wrench, and then checks for additional leaks. This is player experience from the recording's commentary, rather than a personally tested procedure or a complete list of repair inputs. Use the interaction instructions in your current game for the exact action required with the tool.
Check the compartment and the remaining water
Do not assume that reaching the first leak accounts for every problem. The same crew discusses another leak upstairs while working below, then separately deals with water in the submarine. A practical response is to tell your teammates which area you are repairing so another person can check the other reported location.
After the leak work, attend to the pumps in flooded rooms. The commentary reports the water level returning to zero after pumping. That supports checking both the damage and the accumulated water; it does not establish that every persistent flood has one cause or that pumping replaces the repair itself.
Return the wrench to a place your crew can find afterward. In the recording, misplaced tools become an obstacle during a later emergency, which is a useful reason to agree on where repair equipment belongs.
Know about the lower-deck patch
The official 1.0.1.0 changelog, published on October 29, 2026, records a correction for lower-deck pipe leaks. If the trouble is specifically with a lower-deck leak, check whether your installed game includes that update before treating it as a mistake with the wrench.
The official S.O.N.A.R. announcement feed is the place to compare the patch with your problem. Its brief note does not explain the original bug's exact trigger, identify every affected pipe, or promise to fix all flooding. The developer's broader repair description also treats leaks and other critical systems as jobs requiring tools, so keep a pipe repair separate from an unrelated electrical or fire emergency.
FAQ
What tool do I need for a pipe leak?
The supplied player commentary identifies a wrench for the leak repair. Follow your current game's interaction instructions when using it.
Why is water still inside after the leak is fixed?
The crew commentary treats pumping as a separate task after repairs. Check the pumps and remaining damaged areas rather than assuming the repair automatically removes existing water.
Was there an official lower-deck pipe-leak fix?
Yes. The October 29, 2026 changelog for version 1.0.1.0 records a lower-deck pipe-leak correction, without detailing its precise trigger or covering every flooding problem.
