Passive income: NO

Earning passive income from a plumbing side hustle is unlikely for most people. Plumbing requires hands-on work, and while some may automate or outsource tasks, this typically involves significant investment and management. Most plumbers earn actively, and only a few outliers with established businesses and teams might achieve passive income. Common myths include the belief that plumbing can be easily automated or outsourced without ongoing involvement. Realistically, it becomes passive for those who build a large, well-managed business, but not for individual plumbers or small operations.
