Plumbing Repairs
Fixture-level plumbing done right and done legally.
Plumbing Repairs covers the fixture-and-supply work most states allow a handyman to perform. It proves you can swap faucets, toilets, valves, and traps without leaks — and that you know exactly where the licensed-plumber line sits. Everything below is free — no login, no paywall. Work through the skill areas, drill them in Study Mode, and when you're ready, prove it with the certification exam.
