Overview of Free Online Plumbing Courses

Free plumbing courses are most commonly available online in the form of do-it-yourself (DIY) tutorials and can range in difficulty level depending on the extent of the project. Plumbing refers to any system of pipes and appliances that transfers water and other fluids to and from a building, meaning courses can cover bathroom appliances, kitchen appliances, washing machines, and many others. DIY plumbing courses give high-level overviews on the functionality of the appliances being installed or fixed, while training courses for a plumbing diploma give more in-depth explanations on how the plumbing infrastructure in a residence operates.
