About this Course

Plumbing is one of the core building trades, combining practical skills with a solid understanding of water movement, pressure, fixtures, materials, and system design. This course introduces the essential concepts behind residential and light-commercial plumbing systems, including water supply, distribution, drainage, heating systems, fixtures, repairs, piping methods, safety, and basic maintenance. Though originally written for apprentice and professional plumbers, the lessons also provide clear guidance for anyone seeking a deeper, more structured understanding of how modern plumbing systems work and how the major components fit together.

If you'd prefer a more modern, trade-focused version of this subject, you can also explore our updated Skilled Trades Plumbing Course , which covers core concepts, tools, materials, and job-site applications in a streamlined format.
