About this course

Independent GCHS training

Each lesson has a dimensioned diagram, a glossary, 14 practice questions (20 in Lesson 14) and neural narration. Numbers were checked against at least two public sources. Texas cities may adopt a different plumbing code (many use the IPC or UPC) along with local amendments, and plumbing must be done by plumbers licensed by the Texas State Board of Plumbing Examiners, so always confirm the code and amendments in force where the work is permitted. This is training, not a substitute for the adopted code.
