Architecture and Construction, Grade 9 - 12, Plumbing and Pipefitting II, 2009

1.) Calculate 11 , 22 , 45, 60, and 72 degree offsets, parallel offsets, and rolling piping offsets, including using a framing square to find the travel in a piping offset and using a folding rule to find given angles.

2.) Interpret information from a site plan to locate plumbing entry points, wall chases, material takeoff, and drain water, vent pipe, and water supply systems.

•  Developing estimates for installation of piping systems
•  Establishing piping fixture locations
3.) Explain the use of shoring materials and premanufactured support systems used in pipeline installation.

4.) Determine the grade and elevation of a trench for a sewer line.

5.) Identify types of underground piping materials and fittings by size and classification.

Examples: Chlorinated Polyvinyl Chloride (CPVC), Polyvinyl Chloride (PVC), ductile iron, carbon steel

6.) Demonstrate the installation of various drain systems.

Examples: floor, roof, other specified areas

7.) Demonstrate how to service various types of valves used in plumbing and pipefitting applications.

8.) Install a water distribution system using various hangers and fittings.

9.) Install a properly-sized water service line, including backflow prevention.

10.) Demonstrate the installation of bathtubs, shower stalls, valves, faucets, water closets, urinals, lavatories, sinks, and pop-up drains.

11.) Demonstrate safety precautions that must be followed when working on or near electrical equipment.

12.) Calculate wattage consumed by an energized circuit.

13.) Determine voltage, current, and resistance measurements using electrical test equipment.

•  Determining the position of leads for reading voltage, current, and resistance
14.) Identify hangers and supports used to install drainage, waste, and vent (DWV) and water supply systems.

15.) Install pipe hangers and supports according to local codes and manufacturer's specifications.

16.) Demonstrate the installation of common types of fire-stopping materials used in penetrations through fire-rated structural members.

Examples: walls, floors, ceilings

17.) Develop a material takeoff from a given set of piping plans.

18.) Determine the location of fixtures and field routing of plumbing from plans and fixture rough-in sheets.

19.) Describe a building sewer system, a building drain, and a DWV system using appropriate hangers on correct grade.

20.) Determine correct function by testing a DWV system.
