    15. 15. Where do we find a trap?Traps are located under basins, sinks, showers, baths etcThe plumbing code states “The drainage discharge pipe from all sanitary fixtures will be constructed with a trap, or a self sealing mechanical device”Jun 18, 2012 15
    16. 16. TRAPPING THE FIXTURE One type of trap is installed after the fixture is installed. One type of trap is formed in the fixture as part of the manufacturing, for example. (Urinals, Pans etc) This type is called an integral trapJun 18, 2012 16

    20. 20. How do they work?A “U” shaped bend forms a water seal to prevent odours, bacterias and sewer gasses from pipe system coming back into buildings.Read A.S. 3500 CL. 6.4.2 Retained Water SealJun 18, 2012 20
    21. 21. How does it work?A “U” bend in the pipe helps to maintain a water seal that prevents the gas from the sewer getting back through the fixture.Jun 18, 2012 21
    22. 22. What is the water seal? The water will discharge once it gets to the spill level. The “U” shaped pipe under that will hold a water sealJun 18, 2012 22
    23. 23. THE WATER SEAL The designed depth of the water seal in a W.C. and other 100 mm traps is 50mm, +/- 5mm and 75mm (-5 +35mm) for all other fixture traps. After a fixture has been used and the discharge of water completed, the trap must maintain a water seal with a 25mm min. depth.Jun 18, 2012 23

    30. 30. INSTALL DISCHARGE PIPES QUESTIONSJun 18, 2012 30
    31. 31. INSTALL DISCHARGE PIPES1/ Should the discharge pipe, be connected to a fixture, before or after the fixture is fixed in place ? Depending on the circumstances it may be necessary to install the discharge pipe before the fixture has even been installed. In some instances it may be considered a better option if the pipe is installed after the fixture has been installedJun 18, 2012 31
    32. 32. INSTALL DISCHARGE PIPES2/ List 6 factors, that may determine the materials suitable for a given job. Type of usage Class of discharge Properties of liquids conveyed Soil type and conditions Environment factors TemperatureJun 18, 2012 32
    33. 33. INSTALL DISCHARGE PIPES3/ Copper pipe is available in different ‘types’. Which ‘type’ has the thickest wall thickness ? Type ‘A’Jun 18, 2012 33
    34. 34. INSTALL DISCHARGE PIPES4/ In reference to the discharge pipe, what information could you gain from a site inspection ? Environmental factors such as:- exposed to excessive heat from the sun or other heat source, such as a furnace in a factory damaged by a vehicle at a factory where a forklift could crash into the unprotected pipe having exposure to corrosive chemicals such as acidsJun 18, 2012 34
    35. 35. INSTALL DISCHARGE PIPES5/ When installing a pipe that is to pass through a timber beam, why is it regarded better practice to position the pipe through the centre, rather than cutting out the side of the timber ? As cutting through the side has the potential of weakening the overall structure.Jun 18, 2012 35
    36. 36. INSTALL DISCHARGE PIPES6/ Calculate the fall of a 50mm discharge pipe which is to be run 2.8 metres, at the minimum grade allowable by the AS 3500.2. 70mmJun 18, 2012 36
    37. 37. INSTALL DISCHARGE PIPES7/ When creating a material list to be used in the ordering of materials, what should you specify in the structure of your list ? Quantity Size Material Any detail (e.g. DN 100 copper or DN 80 PVC) Jun 18, 2012 37
    38. 38. INSTALL DISCHARGE PIPES8/ Why is it important to check materials off, which have been delivered to you at the work site ? To ensure what you had ordered is in fact what you receivedJun 18, 2012 38
    39. 39. INSTALL DISCHARGE PIPES9/ When you are about to fit the end of a pipe into a fitting such as a bend, why is it important to make sure the end of the pipe has been cut off squarely ? To make sure the pipe is pushed all the way into the socketJun 18, 2012 39
    40. 40. INSTALL DISCHARGE PIPES10/ According to the AS 3500.2, what are the 2 methods for testing discharge pipes ? The hydrostatic water test The air testJun 18, 2012 40
    41. 41. INSTALL DISCHARGE PIPES11/ With regards to an air pressure test, what is the pressure the pipeline must be subjected to and what is the minimum hold time required ? Pressure of 15 kpa Hold time of 3 minutes minimum Can drop a max of 2Kpa from 15kpa toJun 18, 2012 13Kpa within the 3 minutes test time. 41
