Before starting with the actual Learning Project, please familiarise yourself with the information on this page!
How to use this workbookThe DSPP learning support material provides additional teaching aids for the knowledge and practical skills modules based on the NOCC-A21 syllabus that was developed according to the new QCTO curriculum. The workbooks supplement the existing learning material available at the TVET colleges and consist of work assignments, which can be used by the lecturers as part of the assessments. The completed assessments will be filed in the Portfolio of Evidence (PoE) and form one of the admission requirements for the trade test at the end of the apprenticeship.
The workbooks focus on practical, workplace-driven aspects and contribute to personal growth and development of the apprentice. The focus is the apprentice!
The workbooks are arranged under headings (viz. Introduction to the Learning Project, Preparation, Theory, Work Assignments and Assessments, Further Development and Workplace Experience), using colours and icons to help the apprentice navigate easily through the workbook and are designed to suit the level of the apprentice. The mentioned time allocation is applicable to the knowledge and practical modules done at the TVET college only.
Below is a short description of the different sections of the workbook.
Introduction to the Learning ProjectOn page 4 of the workbook, the apprentice is introduced to the Learning Project. The section begins with a motivational quote, picture or story to inspire the apprentice to 'think out of the box' and to apply this mind-set to work with the workbook. With a short paragraph introducing the upcoming Learning Project, the apprentice will have an idea of how the practicals will be applied in class.
PreparationThe next heading "Preparation" is one of the most important parts of the workbook and can be used at the beginning of the Learning Project. The aim is to arouse the interest of the apprentices in the Learning Project by challenging them with problems and questions varying in difficulty and presented in a fun, creative and mostly scenario-based fashion. There is no pressure on the apprentices to have all the answers - this will encourage them to participate.
TheoryThe theoretical section entails the formal process of instruction as set out by the NOCC-A21. The lecturer is aware as to the desired outcomes and range of topics and he/she plans the process in such a way that training is effective and completed within the allocated time frame.
Work Assignments & AssessmentsWork assignments are completed by apprentices in order to assess their knowledge and skills and to determine effectiveness of the training against the stated outcomes. The assessments and evaluations are done objectively and present an opportunity to identify and schedule remedial activities. These must be formally agreed upon between the apprentice and the lecturer. Furthermore, the assessments serve as proof for the completed knowledge and practical skills modules in the Portfolio of Evidence (PoE).
Further Development & Workplace Experience"Further Development" aims to allow apprentices to delve deeper into the featured topics. The format may include references to websites, books, documents, projects or experiments. Lecturers do not formally keep track of apprentices’ activities in this section. The employment of the apprentices at the workplace is aimed to provide “real-life” work experience. The "Workplace Experience" section of the workbook ensures that apprentices complete a variety of tasks at the workplace.

The main advantage of CAST IRON pipe fittings are that they are indeed highly resistant to abrasion, making them the ideal choice for anyone wanting to drain materials such as sand, dishwasher water and garbage disposal. Another benefit is that they are highly durable and practically indestructible. They do not react with most chemicals and won’t melt or burn even in extreme conditions. They have a long lifespan which minimises the need for replacements and repairs.
(https://www.scribd.com/doc/.../Advantages-and-Disadvantages-of-Cast-Iron-Pipe-Fitti...)
GALVANIZED STEEL is steel with a protective zinc coating. This coating has many advantages over other methods used to protect steel, and it makes galvanized steel pipes, fittings and other structures more desirable in many situations. Here are some of the advantages associated with using galvanized steel.
The paragraphs below describe some of the most important types of piping used by plumbers as found in various sources of literature. They also list some advantages and disadvantages related to their use. Some of these products are represented in the pictures above.
1. As you proceed through the notes, try to identify the product you are reading about and write the name in the space below the picture.
2. Throughout the discussion on the next pages you will be asked to explain your understanding of a specific aspect related to a product. Write your answer in the space provided for this task.

Low Initial Cost
The galvanization process usually costs less than other popular methods of protecting steel.
Long Life
The main benefit of galvanized steel is its long life. Galvanized steel pipes, fittings and other structures can last more than 50 years in many rural areas, and more than 25 years in severely exposed urban and coastal environments.
Toughness
The unique metallurgical composition of a galvanized coating makes it very rugged.
Low Maintenance Costs
Because of its ruggedness and long life, less effort is needed to maintain galvanized steel.
Automatic Protection for Damaged Areas
Explain:
360 Degree Protection
The galvanization process protects every part of a structure–every nook or cranny, corner or sharp recess. This 360 degree total protection isn’t available with other coatings.
Easy Inspection
Explain:
Fast Assembly
Once a galvanized steel product is manufactured, it’s ready to be used. There’s no need to prepare, paint or inspect the coating surface. (http://www.hunantube.com)
COPPER PIPING
Copper does not corrode as steel does over time, and has thus been a metal of choice in the plumbing industry for the past century. Plastics such as PVC, CPVC and PEX are competing with copper, but it still remains a popular metal to use.
Copper Pipes: Advantages
Copper is a naturally corrosion-resistant metal, while galvanized steel will eventual leak and break because of corrosion damage. Although it is a durable metal (capable of withstanding 1,000 psi of pressure), copper is also lightweight, which makes it easier to work with (saving on labor costs) and also easier to extend over long stretches without supports. It’s also less expensive than steel and lead-free.
Copper is more friendly than plastic pipes because it consists of naturally occurring metal, whereas synthetic plastic creates a large amount of emissions during its manufacture.

Copper pipes: disadvantages
Although copper pipes are superior in almost all ways to galvanized steel pipes, there are places were PEX and CPVC pipes surpasses copper. Although copper costs less than steel, it costs more than plastic. Copper pipes also encounter problems from water acidity, so they are not good to install for plumbing systems that draw water from a well.
Copper is flexible as far as metals go, but pipes can bend to fit into almost any space necessary. The color-coding of plastic pipes makes them much easier to use for plumbers, who can designate certain colors for hot and cold piping.
When it comes to providing plumbing for your home, you don’t need to make a decision of all copper pipes or all plastic pipes. A skilled plumber will mix the two, using copper for main lines and then PEX and CPVC for branching lines, identifying the best material for each job.
Copper pipes and tubes comes in a variety of TYPES, with different wall thicknesses, ductility and intended usage. The difference between copper pipes and copper tubes is the the way the diameter of the pipe is measured. Copper tube is measured by outside diameter (OD), whereas copper pipes are measured by their diameter (ID). Depending on the plumbing job you are doing, local and national plumbing codes will dictate which type of copper pipe is acceptable.
Type L copper pipe
Type L copper pipe and tube has a thicker wall than type M pipes, making them the preferred choice for longevity. There are two kinds of type L: hard, and soft temper. Type L will be marked with blue along the pipe or tubing.
Hard temper type L plumbing applications include:
• Above ground water distribution
• Above and below ground drainage and venting systems
• Building sewer
temper type L plumbing applications include:
• Water service pipes
• Water distribution above and below ground
Type M copper pipe
Type M copper pipe and tubing is commonly used in residential plumbing because it has thin walls and can be produced and sold at a much lower cost. For water distribution longevity type M is not recommended. Type M copper is also better for heating applications because of the thin wall thickness. Why?
Type M is identified with RED markings along the pipe.
Hard temper type M plumbing applications include:
• Above ground water distribution
• Above ground drainage systems
Soft temper type M shall not be used in plumbing systems.

Type K copper pipe
Type K copper pipes and tubes are the most robust of the four types because they have the largest wall thickness. Type K comes in hard and soft temper and will be identified by markings. Type K copper can be used for many other applications such as: fuel, gasses, HVAC, fire protection systems and vacuum systems to name a few.
Hard temper type K plumbing applications include:
• Above ground water distribution
• Above and below ground drainage and venting systems
• Building sewer
Soft temper type K plumbing applications include:
• Water service pipes
• Water distribution above and below ground. (www.coppertubing.co.za)
The advantages and disadvantages of installing VITRIFIED CLAY PIPES (VCP)
Classic pipe materials are rarely applied in today’s sewer pipes. There are far more advanced and practical materials used for sewer lines. One of the few materials that are still used is clay. These new clay materials are different than those used in the past. Modern clay pipes are superior to classic clay pipes in every way. The clay materials installed in modern sewer line are called vitrified clay pipes or VCP.
VCP is a mixture of clay and other ceramic materials that undergo heating. The materials are immediately cooled down after exposing them to high temperatures. This causes the clay to become tough and sturdy. There are many advantages in installing vitrified clay pipes, but they also have their share of disadvantages.
The advantages
• Reliable because of long-lasting durability
Only a few pipe materials are as reliable as vitrified clay pipes. The vitrification process allows the clay to become more durable. VCP is one of the most durable pipe materials ever created - this is not an understatement. These clay pipes are able to survive hydraulic pressure just like cast iron pipes. They can also withstand chemicals and toxic sewage wastes. VCP has an estimate of 100 usage years. That’s longer than most pipe materials sold today.
• Easy to clean with high pressured water
Hydrojets are plumbing tools that can clean a pipeline effectively. The powerful torrent is able to cleanse clogs and other forms of debris in the pipes. Hydrojets can even remove small to medium roots in the sewer system. The problem with using hydrojets is that it can cause abrasion and damage to the structure of the pipes. Vitrified clay pipes are special in that they can be cleaned with high-pressured with no trouble at all.
• An environmentally friendly pipe
Explain:
Page 8

2. PREPARATION
WORK IN PROGRESS
NOT FINAL
Disadvantages
• Can be difficult to install or repair
Vitrification may cause the clay pipes to become durable but it also makes them heavier. Installing and transporting VCP is a challenge for repair contractors.
• Very vulnerable to root attacks
Clay pipes emit porous substances which attract plant roots. This can put VCP at an disadvantage if there are a lot of plants near the sewer line. You can either lower the plant population or create an underground barrier to protect the clay pipes.
PVC PIPES - Advantages
• Corrosion Resistance
Explain:
• Chemical resistance
PVC pipes exhibit excellent resistance to a wide range of chemical reagents and disinfectant chemicals.
• Reduced failures and blockages in wastewater pipelines
A major concern within any pipeline system is pipe blockages, a costly and complicated problem that can cause untold damage and hours of repairs. Slow flowing water through a pipeline creates more opportunity for potential blockages and failures in a system with many connections. The extremely smooth lining of PVC pipe - when compared to a copper, clay or concrete pipe - reduces water flow resistance and ensures that water reaches its intended destination with proper pressure.
• Quick Installation time
PVC pipe installation has been tested to be over 30% faster (3 hours and 19 minutes vs 5 hours and 12 minutes) than the same size concrete pipe
• Leak free joints
PVC pipes' ultra-smooth surface reduce pumping costs and their leak-free joints eliminate water loss – which can be up to 40% in some old-technology and corrosion-prone piping networks.
• Long service life
Studies show the life expectancy of PVC pipes to be over years.
• Lower cost
PVC pipes offer significant cost savings for projects, even more so when installation, low breakage rates and life-cycle costs are taken into consideration. The longevity of PVC pipes also means the pipes function more efficiently, reducing necessary maintenance and ongoing work to the pipe, thus making it more affordable over time.

• Tree root intrusion resistance
Some pipe materials are more resistant to root intrusion than others. PVC pipes are more resistant to root intrusion because they have fewer joints. Because of their flexibility, the tightly fitting PVC joints are less likely to leak as a result of settlement of backfill around the pipe. (www.plumberrandwick.com.au)
What is „backfill?“
Can you identify any of the tools below?
As part of installing the pipe system throughout a site, the plumber has to complete a number of practical tasks with tools. These include amongst others, cutting, threading, gripping, bending, expanding, soldering and brazing.

Work Assignment 1
Scenario 1A loyal client of the company you are doing your apprenticeship with recently bought a new flat in an older apartment block in Johannesburg.
As per legislative requirements he received a Certificate of Compliance (CoC) for the electrical installation in the apartment but none for the plumbing installation. Unlike in other regions of South Africa where respective by-laws stipulate certificates for the plumbing installation as well, in Johannesburg such is not required. Initially he is ok with this and proceeds with the purchase of the property.
Task 1
Discuss the problem in the group and answer the following questions:
1.1
Do you think a compulsory Certificate of Compliance (CoC) for the plumbing installation when selling a property would be a good idea? Discuss the pros and cons of such a legislative requirement in your group and present your opinion to the rest of the class.
Figure 1: Bathroom basin problem
One evening after his first few nights in the new flat, the client notices a bubbling noise coming from the bathroom.
Immediately he investigates the situation and finds water smelling of washing powder coming up the bathroom basin - as seen in the adjacent picture.
As his flat is on the ground floor level above the basement garage, he suspects the water coming from one of his neighbours living on the first or second floor.
The next morning he phones his property agent telling him to not proceed with the sale until the reason for the problem has been found and professionally fixed. He suggests using a registered plumber to attend to the problem immediately. The property agent agrees and asks the client to phone his plumber of choice.
After receiving the call and the order, your boss assigns the job to one of your colleagues and asks you to join so you can gain valuable experience during your time spent at the company.
At the apartment, the client explains the problem again and shows you pictures he took while the water rose up the waste pipe of the bathroom basin.

1.2
What do you think the introduction of a plumbing CoC could have to do with the topic of this learning project ‘Assemble metal and plastic pipes and fittings using appropriate methods and tools’?
1.3
During the investigation your colleague and you find the problem of the back flow in the basement. One of the waste pipes is partially blocked and creates back pressure, which in turn presses the water upwards into the client's bathroom basin.
Even though the inside of the pipe is freely accessible through the inspection eye, you are not able to unblock the pipe properly.
Your colleague measures the length of the pipe and asks you to come back the next day to replace the blocked piece of the waste pipe on your own as he is booked for another job already.

Work Assignment 2
During the planning phase for the repair/ exchange of the waste water pipe in the basement, you contacted the owner of the parking bay to gain access to the area where the pipe is. Upon hearing that you are a plumber he asked you to visit his apartment during the day in order to discuss work he needs to have done.
After completing and testing the pipework in the basement you go to his apartment.
He gives you a short overview on the plumbing system in the apartment block which includes, among other things, the central hot water system on the roof top which the home owner association wants to replace with individual geyser systems in each apartment.
The client shows you pictures of his neighbour’s geyser installation and asks you to quote him on the exact same system.

Work Assignment 3
You have finished the installation of the geyser to the clients's satisfaction and are currently busy loading your car in front of the apartment complex when the gardener approaches you. He asks you to look at a problem he has encountered in the garden.
He is very concerned about one of the shut-off valves leaking, as he is aware of the water scarcity in South Africa and all over the world.
He asks you whether you can take the top shut-off valve out and replace it with a galvanized pipe only. His reasoning is that there are dedicated shut-off valves to shut off each leg individually anyway.
3.1
Prepare the pipe to the gardeners specification above.
He gives you the following information in order to prepare the pipe:
• Galvanized pipe 3/4”
• Face-to-face measurement 320mm
