Plumbing is the system of pipes, fixtures, and fittings used to distribute water and remove wastewater in buildings, crucial for public health and sanitation. It involves tasks like installing, repairing, and maintaining pipes, valves, and other plumbing components.

Plumbing involves tools and materials for installing and maintaining water and waste systems, including pipes, fittings, fixtures, and tools like wrenches, pliers, and pipe cutters.

An electric circuit is a closed path that allows electricity to flow, consisting of a power source, conductive wires, and components like resistors or light bulbs. Wiring involves connecting these components to form the circuit, ensuring electricity flows safely and efficiently.

"Fixtures" are permanently attached to a property (like built-in features) and usually included in the sale, while "appliances" are movable items that can be taken with the seller, such as refrigerators or washing machines.

Troubleshooting involves systematically identifying and solving technical problems, while repairs involve fixing the identified issues, often through replacement or modification of components.

Plumbing systems are broadly categorized into potable water supply, drainage/venting, and sewage/septic systems, each with specialized functions to ensure safe and efficient water management.
