Plumbers install and maintain plumbing fixtures, fittings, and equipment, ranging from work on household pipes and drains, heating appliances, bathroom and toilet fixtures, and venting systems. Emergency repair work like unclogging drains, or repairing water main ruptures, represents a significant part of their knowledge and experience. They may have to alter structures to accommodate the pipes by roughing in after the frame and roof of a new building are in place. They study the building plans to determine the layout for plumbing and related materials, locate and mark positions for connections and fixtures, cut holes through walls and floors, select the type and size of pipe required and measure, cut, thread, bend, clamp, solvent cement or solder pipe assembly and install valves and fittings securely in position. Once this is completed they test the pipe systems for leaks.
