Which of the following statements correctly identifies the AFT Galley water shut-off valve location?

• A. Under the Sink in the Lavatory
• B. Behind the Galley Counter
• C. Above the Ceiling Panel in the Galley
• D. Below Waste Bin, Above Waste Bin

Answer: (D)

In aircraft galley systems, isolation valves are placed where they can be quickly accessed and won’t be disturbed during normal use. The aft galley water shut-off valve is positioned in the space under the waste bin, above the deck, so maintenance personnel can reach it by opening a small access area without pulling the bin or climbing to a high location. This setup provides a reliable, controllable point to shut off potable water quickly if there’s a leak or when performing work on the galley lines, while keeping the valve out of passenger areas and protected from everyday activity. Locations such as under a lavatory sink, behind the galley counter, or up in the ceiling are less practical for regular access and serviceability, which is why the description of being below the waste bin and above the deck is the correct one.
