Most people are familiar with plumbers who come to their home to unclog a drain or install an appliance. In addition to these activities, however, plumbers install, maintain, and repair many different types of pipe systems. NCCER and Prentice Hall are pleased to present the third edition of Plumbing. To see what kinds of work you might be doing in the plumbing trade, check out the opening pages of each of the modules. Repairing big chillers, installing domestic and chilled water piping, placing fixtures and faucets, fitting and joining carbon-steel piping and even corrugated stainless steel, reading blueprints, and working with a variety of hand tools -- there's much more to plumbing than unclogging a drain! - Preface.
