Water Distribution System

A main water distribution line runs from the tank into the space above the cabin ceiling,from there individual supply lines go to the galleys and toilets.

The distribution lines are usually of reinforced plastic tubing enclosed in an aluminium shroud.The outer shroud prevents leaking water dripping on to the cabin ceiling.The shroud conveys any leaking water to the lower fuselage area via drain tubes.The water then drains out of the fuselage via the drains.
