What does a plumber do?
A plumber installs, repairs and maintains potable-water and wastewater systems.
Duties and work settings
They study plans and symptoms to diagnose leaks, blockages, pressure and joints. Pipe, valve and insulation choices depend on use. A visible drip may signal a wider moisture or building problem.
Skills, safety and entry routes
Keeping drinking and waste water separate is fundamental. Opening walls or changing shared lines requires coordination; check local permits and qualifications.
