A licensed plumber handles anything that touches the pressurized water supply, the DWV (drain-waste-vent) system, the gas line, or fixed gas-fired appliances like water heaters and pool heaters. A typical service call begins with a 15–30 minute diagnosis: the plumber will run faucets, check water pressure at a hose bib (40–80 PSI is normal), inspect supply lines and shut-off valves, and — if the call involves a drain — usually run a snake or scope a camera before quoting the repair. Bigger jobs (re-pipes, sewer-line work, water-heater swaps) require a written scope, a permit pulled in the homeowner's name, and at least one rough/final inspection by the local building department.

A plumber who quotes a major job sight-unseen, refuses to put the price in writing, or asks for more than 30% up front. Door-to-door "I noticed something wrong with your house" pitches after a storm are almost always scams.
