Every tool a plumber reaches for, in plain English: what it does, how to use it, the tricks experienced hands know, and what goes wrong. Thirty-one animated models show the tool at work, and the cordless ones are styled after Milwaukee red-and-black tools, with the real model numbers and a link to each maker page for photos. Build a starter kit and check off what you own. Local notes are for Montecito, where the County permits and inspects.
