The cabin that needs the most maintenance and why

Engineering department, Wonder of the Seas. Cabin 10044 and the six cabins around it on port side Deck 10 have a recurring plumbing issue related to the ship's vacuum waste system. The main vacuum line runs directly behind those cabins and a junction fitting at that point occasionally loses pressure, causing toilets to flush weakly or make unusual sounds. We fix it every turnaround day and it works fine for about four days before the pressure drops again. It has been this way since the ship launched. Guests rarely notice because the effect is subtle — the toilet works, it just sounds different. But if you are in that section and your toilet sounds like it is gargling, now you know why. Engineering is aware. The permanent fix requires a dry dock modification.
