In the A319 lavatories, where are the water shut off valves located?

• A. Under the sink behind the access door below the water heater.
• B. Behind the access panel located on either the right or left hand side of the toilet.
• C. Behind the access panel located directly at the front of the toilet shroud.
• D. All of the above.

Answer: (D)

In this scenario, you’re being tested on where the potable water shut-off valve can be found in an A319 lavatory. The design of aircraft lavatories often includes several access points to reach the valve, so maintenance and isolation can be done without disassembly. In the A319, the valve can be located behind the sink access door below the water heater, behind an access panel on the right or left side of the toilet, or behind the access panel at the front of the toilet shroud. Because any of these panels may house the shut-off valve depending on the specific aircraft configuration or maintenance access, the correct choice is that all of the above locations are possible. When you need to isolate the water, check these panels in sequence and operate the valve there, typically a simple turn, to stop the flow.
