Water Tank Plumbing Designs Drawing with Pipe Slope Details.

This water tank plumbing design drawing presents a clear AutoCAD representation of plumbing layout and drainage connection details. The drawing shows pipe alignment from the water tank outlet to the drainage system, including pipe diameter markings such as 150 mm and slope indications for proper water flow. Details such as minimum pipe gradient of 1 percent and roof slope of 2 percent are clearly illustrated to ensure effective water discharge. The section view highlights pipe elbows with 45-degree bends, horizontal and vertical pipe connections, and fixing positions within masonry work. Material layers such as sand bedding and structural support below the pipe are also indicated for construction clarity.
