About this Unit

An important part of building construction is the ability to read and understand the information shown on a construction drawing or a set of construction drawings. The drawings show what plumbing facilities are required by using symbols and abbreviations to identify the real material items. The symbols and abbreviations on the construction drawing tell the plumber the location of water and waste pipelines, the type and size of pipe, the type of fittings for pipeline connections, and the location of all the fixtures required.

Once you can read and understand the information on a construction drawing, you can determine the lengths of pipe required by type and size, the number of different types of fittings by size, and the number of different types of fixtures. You will be able to make a list of plumbing materials needed to install any part of or all of the plumbing system.
