After this course

What you'll be able to do yourself.

Weak showers, smelly bathrooms, basins that gurgle. Nearly all of these trace back to height difference, water seals or the path air takes. You learn to track them down on site, then draw them correctly on the sheet.

  1. 1Work out tap pressure from the height of the roof tank
  2. 2Size a roof tank and the load its base has to carry
  3. 3Trace a bathroom smell to the water seal, the vent or the drain
  4. 4Draw soil and grey water lines with the right fall
  5. 5Place vent terminals and roof drains correctly on working drawings
  6. 6Read and draw a pipe penetration detail in a wet floor

Good for

  • Junior drafters who draw plumbing plans and toilets
  • Architecture and civil students who want to understand water in a house
  • Site supervisors who field complaints about smells, leaks and weak flow

  • Nadia Kusuma

    Interior architect

    I finally understand why the MEP engineer always asks for a bigger shaft.

  • Dimas Prakoso

    Architecture student, final year

  • Intan Permatasari

    Civil engineering student

    Pipe falls, shaft space, service points. Everything I used to discover on site.
