Browse Forums Building Standards; Getting It Right! 1 Apr 27, 2017 12:35 am Hello, I have 2 dowpipes on the same side of the house but one of them enters the ground next to the wall whereas the other one is shifted. Any reason why it would be done this way? This is my side access so I worry that the pipe that is shifted is going to restrict it. Also, how far from the house would be the pipe that is buried in the ground? I can imagine both downpipes are connected to it. Thanks PS.

The first downpipe will be plumbed the same way as the second, if you scrape a few inches of soil away from the first downpipe, you will see the horizontal pipe run 90 degrees to the wall. The horizontal pipes appear to be too high. For a single dwelling, if the stormwater pipe is not subject to vehicular loading and there is no paving, the pipe must be buried a minimum (from the finished surface at the top of the pipe) to a depth of 100 mm. If the area is to be paved with brick or un-reinforced concrete, the pipe must be buried from the top of the pipe a minimum of 50 mm below the underside of the pavement. Those vertical slots you see in your brickwork are your weep holes and your DPC is at the bottom. The height of your DPC above the finished ground level is also important. The BCA refers to AS 3700 which states: "The height of a DPC, or flashing serving as a DPC, (see Figure 3.3.4.1), must be not less than— (i) 150 mm above the adjacent ground level; or (ii) 75 mm above the finished surface level of adjacent paved, concreted or landscaped areas that slope away from the wall (see Figure 3.3.4.1); or Explanatory information: 150 mm clearance between the DPC and adjacent ground level reduces the risk of the effectiveness of the DPC being affected by changes in the surface level. Where changes in surface level are less likely to occur, such as where the adjacent surface is finished with paving, concreting or landscaping, the height of the DPC above that surface may be reduced to 75 mm. When also protected from the weather by a carport, verandah or the like the height of the DPC may be reduced to 50 mm." If you are in a low rainfall intensity area, then further reductions in the height of the damp proof course apply. http://www.weinspecthomes.com.au/wp-con ... -sheet.pdf As a quick indication of levels, a course of standard bricks is 75mm. 3in1 Supadiverta.
