Plumbing
There is a rough plumbing plan included in the floor plans that shows the symbols and locations of the kitchen and bath fixtures. However, the location of where the pipes come into the house is site-specific and not included in the plans. Plans for plumbing systems mainly include drawings for water supply systems, drainage systems, irrigation systems, and stormwater systems. A water supply system drawing will show hot water piping, cold water piping, and hot water return piping.
