The work of a plumber is more complex than many people imagine, primarily including: 
    Installation and Assembly: Installing pipes, sanitary fixtures (toilets, sinks), water heaters, dishwashers, etc. Involves cutting, bending, and connecting pipes made of different materials such as copper, steel, and PVC. 
    Detection and Repair: Use professional tools (such as endoscopes and pressure gauges) to locate and fix issues like leaks and blockages. Clean drainage pipes, repair or replace damaged pipelines and components. 
    Maintenance and Planning: Inspect the existing pipeline system to ensure its proper operation. Review architectural drawings and specifications, and coordinate with owners and architects

Plumber needs professional hole cutters, drill bits, saw blades for percussion drilling and efficient works.
