<p>This architectural drawing is a Drain riser design in detail AutoCAD 2D drawing, CAD file, dwg file. The most unfavourable water network in the building's structure's "Source" node is where the Riser calculates the lowest required pressure to satisfy that pressure. This process is similar to that used in internal water supply network design. For more details and information download the drawing file. Thank you for visiting our website cadbull.com.</p>
