This document is a curriculum guide for instructors teaching vocational preparation for plumbing to special needs students. The purpose of the curriculum guide is to provide minimum skills for disadvantaged and handicapped students entering the mainstream; to supplement vocational skills of those students already in a regular training program (mainstream); and to provide vocational instructional materials for the modified classroom. Ten units of self-paced and self-contained instructional materials are contained within the plumbing curriculum. Units are illustrated and simplified to more easily aid a student in class activities or on an individual basis. The separate sections of each unit are color coded and consist of the following: objective and student assessment (presents the unit objectives and provides self-assessment statements for students); introduction (contains a brief motivational statement describing the theme of the units); tools, materials, and equipment needed to complete the exercise; steps of the procedure, with illustrations; and student evaluation to be used by the instructor. Topics covered in the 10 units include job opportunities in welding, safety rules in plumbing, measuring and cutting pipes, reaming and threading pipes, soldering, making a flare joint, making a plastic pipe joint, repairing faucets, replacing a toilet bowl, and clearing a main drain.
