Plumbing course


Introduction to Plumbing Pipes and Fixtures is a vocational course designed for anyone wanting to learn more aboutplumbing. … The installation of long-lasting plumbing pipes ensures that these basic requirements are met


1. The application of basic plumbing hydraulic theory, the design and sizing of piping, and the selection of components are according to the following qualitative specifications:

  • SABS 0254: 2000 The Installation, maintenance and repair of fixed electric storage water heating systems
  • SABS 0252: 1994 Water supply and drainage for Buildings:
  • Part 1: Water Supply installations for Buildings, and
  • Part 2: Drainage Installations for Buildings
  • SABS 0400: 1990 Code of Practice for the Application of the national Building Regulations, Part P: Drainage2. Pressure includes: absolute, gauge, atmospheric, and negative (vacuum) pressures, and their relationship to height.3. Water principles include: Hydrogen bonds; Surface tension; Capillary action; and Meniscus;4. Quality of water principles include: hardness/softness; solubility; suspended solids; salinity; turbidity; bacterial levels; scaling.

    5. Erosion principles include: damage to components, and the misapplication of components.

    6. Pollution includes for: Effluent, and backflow prevention.

    7. Pipe design and sizing includes: selecting one or two pipe designs; determining site and structural constraints; select practical routing; determining available supply pressure; determining required terminal pressure; determining friction loss factors; determine maximum design velocity; and determine probability of simultaneous use.

    8. Permissible friction losses are calculated per meter run and for the whole system.

    9. Pipe sizing includes for: selection from pipe manufacturers friction loss tables; checking against max velocity; checking against total permissible loss.

    10. Valves include: globe; ball; plug; float; butterfly; gate; RSV; diaphragm; control, air relief; vacuum relief; pressure reducing; pressure relief; temperature and pressure safety. Also: strainers/filters; fire/hydrant; actuators; and solenoids.

    11. Meters include: volumetric/rate of flow, Types: rotary piston; fan wheel – inferential; helix; woltmann; and turbine. Understand: vortex shredding; orifice plate; magflow; turbine; combination; and the legal requirements and restrictions.

    12. Pumps include: positive displacement, piston; diaphragm; mono; impeller, (centrifugal and primed); self-priming; turbine multistage; hot water circulating; submersible; borehole; basic pump installations, and hand pumps.

    13. Pipe and fitting materials include: Copper, High density Polyethylene (HDPE); Polypropylene, uPVC; Wrought steel; Seamless steel; Cast iron/Ductile iron; Fibre cement, etc.

    14. Hot water systems include: Pressurised storage; Roof tank fed; Combination; Push-through (open outlet); Instantaneous; Heat pumps; Storage calorifiers; Trace heating; Solar (direct and indirect) two part; Industrial; Insulation; and Circulating flow and return.

    15. Terminal fittings include: Screw down taps & mixers; Ceramic disc taps & mixers; Medical; Electronic; Thermostatic; Demand; Metering; Flush valves; Shower mixers; Disabled; and an understanding of Water and Energy conservation.
