Accept who you are. Nowadays, we are encouraged to accept everyone for who they are whether we like them or not; and that pretty much goes for everyone. Just as there are differences among people, there are many differences among the piping and components used to build plumbing systems. While plumbing engineers design systems that allow people to live and work in the spaces architects plan, the plumbing contractors are the ones that ultimately need to put it all together and make sure it works.
Contract documents typically consist of drawings and specifications, at a minimum. The drawings are where we put all of those lines and circles. The specifications, also known sometimes as the project manual, are the “wordy” documents that tell the contractor what types of materials to use. Piping comes in a wide variety of materials: Copper, steel, cast iron and plastics. Most of us are familiar with copper piping used to convey gases and water. Cast Iron is another stalwart material that was the standard drainage piping for decades. Then, there is steel piping used for fire protection and natural gas.
