Water Drainage System Diagram

To prevent erosion make a rock bed around the end of the tube.

Water drainage system diagram. Where the tube passes by the downspout from the gutter we installed a y fitting and drained the roof water from the gutter system directly into the main drainage line. This diagram of a typical dwv system is called a plumbing tree. When checking the slope of the ground in this area we find that it is too flat and therefore needs to be built up to get the water to drain away from the house. Water comes in from the city pressurizes everything including your water heater goes down a common drain and away from you to a city sewer disposal plant or your own septic system.

Immediately beneath a sink bathtub or other plumbing fixture the fixture drain opening leads to a curved segment of pipe known as the p trap which is normally a 1 1 4 to 2 inch diameter segment of pipe with a sharp curved bend in it shaped like the letter p. Water runs down the sink drain into a p trap so called because it s shaped like the letter which fills up with water to prevent sewer gases and odors from getting into the house through the pipe. The most critical problem in the above drainage diagrams is the water that builds up right next to the foundation in the front yard. If water is to flow out freely and waste is to exit properly all components of the dwv must be present and in good working order.

Screw a drain cover over the end of the tubing as it approaches daylight to keep critters out.
