16. How Clean is the Water?
As a rule thumb, you should NEVER drink water from the lavatory tap on airplanes. But the potable water used in coffee and tea is safe to stomach, right? Well…according to the account of many flight attendants, it sounds like it’s best to stick to the bottled beverages and get your caffeine fix on the ground.
Although the tanks for those drinks are cleaned, there still remains the question of how often those custodial tasks are performed. Apparently, the answer is not as often as you would think, and the valve for cleaning lavatory waste is pretty close to the one for filling clean water. That’s a bummer for those long, international trips.
