What does a Plumber do?
A plumber installs, inspects, and repairs piping systems that move water, waste, and gas through residential and commercial buildings. This trade requires precise assembly of pipes, fittings, and fixtures to meet strict building codes and safety standards. You fix leaks, clear blockages, and replace defective components to keep essential utilities functioning correctly. The work demands physical skill with hand and power tools alongside technical knowledge of pressure systems and drainage mechanics.
- Install and connect pipework, valves, and plumbing fixtures according to blueprints and local code specifications. You assemble water supply lines and drainage systems using copper, PVC, or PEX materials, ensuring every joint is sealed to prevent leaks. This process involves measuring, cutting, and threading pipes to fit specific spatial constraints within walls, floors, and ceilings.
- Inspect and test installed plumbing systems to confirm they operate safely and efficiently under pressure. You use pressure gauges and hydrostatic testing methods to identify weak points, hidden leaks, or improper connections before finalizing a project. This verification step prevents future water damage and ensures the system meets regulatory requirements for public health and safety.
- Repair and maintain existing plumbing infrastructure by replacing broken pipes, fixing faulty fixtures, and clearing clogged drains. You diagnose issues such as low water pressure, slow drainage, or visible leaks, then execute targeted repairs to restore full functionality. This work often requires accessing confined spaces and working around existing structural elements to replace defective parts without causing unnecessary disruption.
