The primary function of bibliographic citations is to assist the reader in finding the sources used in the writing of a work. To these basic citations, the annotated bibliography adds descriptive and evaluative comments (i.e., an annotation), assessing the nature and value of the cited works. The addition of commentary provides the future reader or researcher essential critical information and a foundation for further research.
French drain. A French drain or weeping tile (also blind drain, rubble drain, rock drain, drain tile, perimeter drain, land drain, French ditch, sub-surface drain, sub-soil drain or agricultural drain) is a trench filled with gravel or rock or containing a perforated pipe that redirects surface water and groundwater away from an area.
Clean out the French drain using the pressure cleaner. If you suspect a clog, be very careful to stand to the side when you fire the water down the drain. Try to angle the stream of water to hit first the bottom of the length of the drain, then the sides.tep 3. Use the garden hose to send a steady stream of water down the French drain. Do not start out with the pressure cleaner because if the drain has a major clog, you will just end up with lots of water firing back in your face.
