Theparts C and E are unions that permit the pipe or bowl to beremoved without disturbing the remainder of the the form of the trap it will be seen that the U-shaped partbelow the dotted line F will always remain full of water and soprevents the escape of air from the sewer.

To clean the trap the screw-plug D istaken out with a pair of pliers and the obstruction removed with Fig. 94.—Corner wash basin.
