Terminology

  1. Plumbing Fixtures, Fittings and Equipment
    Plumbing fixture
    : Is a device which is part of a system to deliver and drain away water, and is also configured to enable a particular use. It is an item that has been annexed to a property to such an extent that it becomes part of it, ie the article cannot be removed without significant damage to the land or building Examples of fixtures include water closets (also known as toilets), urinals, bidets, showers, bathtubs, utility and kitchen sinks and drinking fountains.
    Plumbing fittings
    : . A fitting is more commonly regarded as an item that is easily removable from the land or building. It is used to connect tubes made of mechanically worked and toughened. Components of a highly specific size, type, or class which can be used to interconnect custom designed or purchased components within a run. In addition to the straight pipe or tubing, many fittings are required in plumbing systems, such as valves, elbows, tees, and unions..
    Plumbing equipment:
    includes water meters,pumps, expansion tanks, backflow preventers, filters, water softeners, water heaters, wrenches, heat exchangers, gauges, and control systems.
  2. Plumber-: is a person who installs or repairs>piping systems, plumbing fixtures and equipment such as water heaters.
  3. Materials -: At present times the materials used are high-pressure pumps, pipes made of copper, brass, plastic, or other nontoxic material. Drain and vent lines are made of plastic, steel, cast-iron, and lead. Lead is not used in modern water-supply piping due to its toxicity.
  4. Pipes And Tubes -: A pipe is typically formed via casting or welding. Pipe normally has thicker walls and may be threaded or welded. A tube is made through extrusion is thinner-walled and requires special joining techniques such as 'brazing', 'compression fitting', 'crimping', or for plastics, 'solvent welding'.
  5. Traps and vents: All plumbing fixtures have traps in their drains; these traps are either internal or external to the fixtures.
    Traps:
    These are pipes which curve down then back up; they 'trap' a small amount of water to create a water seal between the ambient air space and the inside of the drain system. This prevents sewer gas from entering buildings.
    Vents-:
    Each fixture drain is vented so that negative air pressure in the drain cannot siphon the trap dry and to prevent positive air pressure in the sewer from forcing gases past the water seal also to prevent explosive sewer gas buildup.
  6. Tap ware-: is an industry term consisting of water taps or faucets and their accessories such as water spouts and shower heads.
