4 Credit(s)

Designed for Oregon state-registered apprentices employed in the plumbing trade. This course reviews methods for finding angles using the Pythagorean Theorem. Students will interpret and use civil, architectural, structural, mechanical plumbing and electrical drawings when installing plumbing systems. Techniques to create isometric drawings, material takeoffs and approved submittal data using will be included. Methods are introduced for attaching and running DWV and water supply piping in relation to structural elements and code requirements.

Learning Outcomes
Upon successful completion of this course, the student should be able to:

1. Calculate 22-1/2-, 45-, 60-degree offsets, parallel offsets and determine square of a corner.

2. Draw simple and rolling offsets, as well as offsets on parallel runs of pipe.

3. Read and interpret building plans and drawings.

4. Create an isometric drawing and prepare elementary single-line sketches of drainage and vent systems.

5. Layout a building site including fixtures through building sewers including building the stack location.

6. Prepare a materials list for a drainage waste and vent system using approved submittal data.

7. Explain applications for installation of hangers, supports, and fire stopping for plumbing systems.
