ELEMENT 1: PLAN AND PREPARE FOR INSTALLATION

LEARNING OUTCOMES

As you go through this element you need to ensure that you acquire the knowledge, skills and attitudes required to plan and prepare for installation. Your learning facilitator is there to assist you through the various activities so on completion you should be able to:

In Plumbing, you will install such things as pipes, fixtures and other equipment for brining in water supplies, and sending away waste, in buildings. Plumbing will also be needed for domestic machines which make use of water and other piping. Some plumbing equipment around the home includes:

• Gas water heaters

• Cooking stoves (electric)

• Dishwashers

• Washing machines

TOOLS

As a plumber, you will be helpless without your tools. Depending on the installation work to be done, the tools you will need for putting in pipes fixtures and valves will vary. Tools and equipment you may require include:

• Hack saws

• Pipe wrenches

• Pipe vices

• Stock and dies

• Pipe cutters

• Swaging tools

• Hand drills

• Tube cutter – plastic and copper

• Cold chisels

• Pipe reamers

• Files

• Screw drivers

• Hammers

• Measuring tapes

• Concrete drill bits

• Flaring tools

INTERPRETING WORK INSTRUCTIONS

For your plumbing jobs, you will need your tools and materials, but, equally important, you will also need to learn how to follow blueprint readings and specifications. As said before, finding the perfect fit, and keeping to industry standards, is of paramount importance.

There is no room for mistakes in these plumbing activities. Look closely at the work instructions/ specifications, which will tell you about how to do the installation, what materials of use to complete the joints and how to check for a perfect fit.

Blueprints

On the Blueprint, standard symbols for plumbing, piping and values include the following;

• Piping symbols: These represent the various plumbing fixtures, piping systems, pipe fittings and valve which all go together to make up the system.

• Plan Views: On your mechanical blue prints, look for plan view\s of the plumbing fixtures as well as drawings. A plan view appears as if you are looking down into the various rooms in the building.

• Schematics: A schematic or diagrammatic piping drawing is the outline (drawing) of an entire piping system. This will not necessarily be drawn to scale or the exact location

Refer to: Ripka, L. V., Plumbing; pages 5-8 for more blueprints

Isometric drawings. If you intend to become a professional plumber, on thing that you should also know is how to read and create an isometric drawings. Isometrics is there special language that all building professionals use to communicate their needs and ideas when discussing plumbing systems. The isometric drawing shows a three-dimensional view of the location of pipes in your plumbing system.

Refer to: Massey, Howard C., Basic Plumbing with Illustrations; page 16-21

for more information on how to draw an isometric drawing

Specifications

On the blueprint, symbols represent the various plumbing fixtures.

The architect will provide written instructions for you called specifications. These are used along with the blue print or work drawings. The specifications will vary in number according to the size of the job. Instructions will include information like quality of workmanship, brands and types of plumbing fixtures and equipment. They may also touch on legal responsibilities and insurance matters, as work that is not done right will attract penalties and incur costs which someone will have to pay

TYPES OF PIPES AND FITTINGS

The types of pipes and fittings you will use in your plumbing according to the

kind of installation being made and the instructions given on your blueprint and specifications.

Correct Sizing

The size of pipes, vents and fixtures is determined by the load that each will have to carry.

For example, as waste pipe of two inches which is being used to serve one toilet or laboratory , will use a minimum vent size of 1 ¼ inches. Your plumbing specifications will state the sizing and fixture type you will need. Please pay close attention to these.

Sizing the vent system

Various things will determine the size of the vent pipe, as well as the solid and waste pipe. For the vent pipe, look for things like the maximum load which the pipe will carry, the developed length of the pipe, the type of plumbing fixtures to be vented and the diameter of the pipe or waste stack he vent pipe will serve.

Sizing also varies according to the size of the buildings. Some building types in which plumbing will vary include:

• Single family dwellings

• Duplex residences

• Apartment buildings

Venting regulations

• For each building with one toilet or sewer, there must be at least one minimum size vent stack of not less than three or four inches going out and above the building’s roof.

• No wet or dry vent serving a water closet can be less than 2 inches in diameter.

• The diameter o the vent stack must not exceed the diameter of the soil or waste stack to which it connects.

Refer to: Basic Plumbing with illustrations, by Howard C. Massey for more on venting regulations. Pages 33-44

Positioning of pipes and fittings and vents

Positioning of pipes, fittings and vents must be done according to the regulations and specifications. Check your blueprint to show where all installations should be made and in what manner.

Check for damage before and after completion of installation. Make sure that all connections you have made are mechanically sound and water tight. You will check for:

• Pressure

• Leaks

• Fix defects

Leaks must be repaired and cracked and defective piping and fittings removed and replaced. When all is in order, the plumbing inspector can then be informed that your newly completed system is ready for a test.

[pic]Refer to. Ripka, L. V. Plumbing; Chapter 1, for procedures relating to the testing and

inspection of plumbing systems.

HEALTH AND SAFETY

Plumbing operations normally includes the installation, preventive maintenance, and repair of water supply systems, sewage and water disposal systems, natural liquefied petroleum gas (LPG) or other gas supply systems (to include gas appliances), and oxygen supply systems. These systems and the maintenance of them contribute to the total well-being of all.

Dangers or hazards encountered during plumbing operations include, but are not limited to, entry into an oxygen deficient atmosphere (confined space), fire or explosion (by introducing an ignition or flame source into a hazardous environment), and falls. Cave-in of an excavated area, burns from heat producing equipment, strains and sprains of the back (or other muscle group), and cuts and/or bruises, are also potential dangers.

[pic]

Working in confined or small spaces, handling heavy and awkward materials, being subjected to numerous obstructions in limited working space, and health related hazards are situations in which accidents can happen. Plumbing maintenance workers need to be knowledgeable of these potential hazards and conditions and take reasonable actions to prevent incidents before they occur. Anytime you work with tools safety must be your primary concern. A few general rules to keep in mind are:

1. Protective glasses or goggles should be worn whenever power tools are in use; and when chiselling, sanding, scraping, or hammering overhead, especially if you wear contact lenses.

2. Wear ear protectors when using power tools, since some operate at noise levels that damage hearing.

3. Be careful of loose hair and clothing, so they don't get caught in tools.

4. The proper respirator or facemask should be worn when sanding or sawing or using substances with toxic fumes.

5. Keep tools in good repair. Otherwise, some may slip and cause accidents.

6. Always use the appropriate tool for the job.

7. Repair or discard tools with cracks in the wooden handles, or chips in the metal parts, that could fail and cause injury.

8. Don't drill, shape, or saw anything that isn't firmly and properly secured.

9. Take care in storing oily rags, which can spontaneously combust.

10. Don't abuse your tools.

11. Keep a first aid kit on hand.

12. Don't work with tools if you are fired. That's when most accidents occur.

13. Read the owner's manual for all tools and know the proper use of each.

14. Keep all tools out of reach of small children.

15. Unplug all power tools when changing settings or parts

Personal Protective Equipment

Personal protective equipment worn during plumbing maintenance operations normally consists of eye and/or face protection, work or chemical resistant gloves, and safety-toe shoes. A bump cap or hard hat may be required under conditions that could result in head injuries (e.g., work in manholes and in close spaces with low overhead pipe or other obstructions).

Eye or face protection is required while working plumbing connections, with chemicals, or where an eye hazard could exist while using tools or machines, and while working on pressure systems.

Handling Power Equipment

Early in your plumbing career, you will be sure to discover the oxyacetylene torch which is useful for all sorts of purposes when constructing buildings. Please note that this piece of equipment, just like other power tools, should be used with the utmost care and stored properly after use.

Scaffolding Safety

If you need to install some plumbing in the ceiling, you may need to set up some scaffolding. Make sure that he scaffolding is constructed properly, otherwise you and your workmates will be in danger of falling, being injured by falling tools or spilling your materials. Try using tubular steel scaffolds, but do not allow them to rusts. Do not overburden them with materials in addition to your weight.

and safety codes of practice ( ) ( )

ELEMENT 3: TEST EQUIPMENT

LEARNING OUTCOMES

As you go through this element it will provide you with the knowledge, skills and attitude required to test equipment. Your learning facilitator is there to assist you through the various activities so on completion you should be able to:

1. Ensure that correct testing procedures are used.

Your work is only half complete when pipes and fittings have been positioned in location. Your next important job will be to test the pipe for leaks and also to ensure that your installation is done according to the regulations. Leaks shall be located by testing short sections of pipe. Leaks shall be repaired and the reach of sewer retested. Check also for that all pipes and fittings are free from defects, are shaped correctly and have no surface imperfections.

[pic]

[pic]Refer to: For more on testing completed installation works,



There are two basic requirements of all plumbing codes when it comes to testing and inspection. The first thing is that you need to supply all equipment, materials, power and labour which you will need for each test and inspection.

The next thing is that no work may be covered (with dirt, or enclosed wall, or ceiling) until this testing and inspection has been completed.

[pic]

All plumbing tests should follow these guidelines:

1. Assemble the testing apparatus or equipment.

2. Seal all openings.

3. Apply the test

4. Check for the leaks

5. Fix the defects or problems

6. Call for an inspection and test

7. Assist the inspector at the time of the test

8. Remove testing apparatus when the test and inspection is completed

[pic]

[pic]Refer to: Ripka, L.V. Plumping, page 255

Your will need to seal all openings since plumbing tests are pressure tests. Close them with pipe caps, plugs or a test plug. In a air tests, all traps must be filled with the proper amount of water in order to seal it. No one wants to know that they have installed plumbing which is defective. This is why testing when the job is completed is so important.

Areas to be tested include

1. Building sewers

2. Water service

3. Sanitary drainage and vent systems

4. Drinking water supply and distribution systems

5. Storm drainage systems

6. Plumbing fixture installation

Types of tests include Air tests, water tests, hydrostatic tests and odorant leak detection.

[pic]

[pic]Refer to: Ripka, L.V. Plumbing, Chapter 11.

If you find a lot of damaged material and piping when the tests are complete you can take these back to the manufacturer to have them replaced. If the entire system is defective, and the manufacturer refuses to take the blame, you may need to see your lawyer, as you may not be paid for your work. With legal assistance, you may be able to get replacement materials so you can redo the Plumbing job.

ARE YOU READY TO TEST YOUR COMPETENCY?

Now that you have completed this element, see if you have fully grasped all the components by doing the following self-assessment:

Checklist 1 Yes No

1. I know how to use correct testing procedures ( ) ( )

Checklist 2 Yes No

1. Correct testing procedures are used

ELEMENT 4: CLEAN UP AREA

LEARNING OUTCOMES

As you go through this element it will provide you with the knowledge, skills and attitude required to clean up area. Your learning facilitator is there to assist you through the various activities so on completion you should be able to:

1. Remove all waste material and dispose of them.

2. Clean up the area related to your work activities.

3. Tools and equipment must be cleaned, maintained and stored.

It is time to clean up. Some left over materials, excavated building material or dirt, spilled liquids and other materials must be removed, leaving the area quite clean. Your tools will also have to be cleaned, to preserve them, and also in preparation for the next job!

WASTE REMOVAL

Make sure to properly dispose of broken fixtures and other sharp, pointed waste material. improperly disposed of, these may end up inside trash bags or the community sewage treatment plant where they may puncture a trash collector's or sewage worker's skin – even through their clothing. Alternatively, these may up on the ground where they can injure anyone who comes in contact with them, even if they are wearing shoes.

The safest and recommended method to package such material is in a container specifically designed for them. Chemicals should be treated as hazardous and handled with care. Seal all containers and take away with you.

[pic]

Cleaning up

Imagine that you have just completed the installation of pipe work for a customers new washing machine. The pipes are in, the hot water is flowing, there are no leaks. Everything is in order. Do you then just take up your tools and leave? Of course not. The plumber who cares about leaving good impressions and about his tools will

• You can never use too much water to clean up

• Do not allow cement mixtures to sit in the mixing bucket. Immediately after mixing, and use pour the remainder away and wash container in which mixture was made.

• Clean up of concrete surfaces and pipes can begin 30 minutes after job is complete.

• Remove excess materials from concrete surface with a wooden float, or pour or spray large volumes of clean water onto the surface.

• Lightly scrub the surface with a white nylon pad to loosen any chemical leftovers.

• Remove any white sudsy water layer by using a heavy nap towel, frequently changing the rinse water. Use of dirty water will redeposit resins onto concrete/ pipe surfaces.

CLEANING AND CARING FOR YOUR TOOLS

Caring for your tools is also extremely important if they are to do the jobs for which they are intended.

1. Keep your tools property cleaned and lubricated.

2. Keep your tools out of the weather and store them out of the way when not in use.

3. If the storage area is damp (in the basement, for example), install a dehumidifier and keep tools covered with a film of rust-inhibiting (preventing) oil.

4. Never throw tools into the toolbox. Handle them carefully to avoid dulling edges and nicking surfaces.

5. Whenever possible, hang tools with cutting edges separately to keep them from getting nicked or dulled.

6. Purchase carrying cases for your power tools to protect them and to store their accessories.

EQUIPMENT STORAGE

After they are properly cleaned, your tools, equipment and materials must be stored in a safe area where they will not cause harm to others and where they will not be damaged. Place power tools in their special cases and put away other equipment in your tool box.

Hang others in a safe place. Store materials and chemicals where they will not be affected by the weather, by animals, interfered with by children and where they will not be mistaken for other substances.

ELEMENT 5: INSPECT AND NOTIFY COMPLETION OF WORK

LEARNING OUTCOMES

As you go through this element it will provide you with the knowledge, skills and attitude required to inspect and notify completion of work. Your learning facilitator is there to assist you through the various activities so on completion you should be able to:

1. Undertake final inspections to ensure that installed equipment conform to requirements.

2. Notify Work Completion in accordance with established procedures.

Inspection is the final stage in your pipe installation project. Through the issuance of permits and the requirements of public inspection, a community can assure itself of proper plumbing code enforcement. The permit allows the plumbing inspector to protect the consumer by assuring plumbing installations are done properly. The inspection of such plumbing work insures that the installation is being completed in accordance with At the start of this module, we discussed with you the importance of obeying all regulations and codes while installing pipes.

[pic]Refer to: remind

yourself of some of these codes.

TYPES OF INSPECTION

The following is a brief description for each type of inspection. These descriptions provide examples of the basic construction features that are inspected.

Water Service: Inspects water line from meter to the building for proper depth of burial, approved piping materials and fittings. The ditch must remain open until inspection approval.

Sewer Service: Inspects connection of the building drain to the sewer for proper depth of burial, approved piping materials and fittings. The ditch must remain open until inspection approval.

Groundwork: Inspects all underground plumbing other than water and sewer service lines. All underground piping must be pressure tested for leaks at the time of the inspection. No portion of the underground piping may be covered until inspection approval.

Gas Piping Rough-In: Inspects the location, sizing, installation and pressure test for all gas pipes prior to concealment by insulations, walls, floors or ceilings.

Rough-In: Inspects water, drain and vent piping for proper sizing, fittings, piping materials and location prior to concealment by insulation, walls, floors or ceilings. All piping shall be pressure tested for leaks. All vents are to be installed and ran through the roof. Roof collars are to be installed at this time.

Gas Piping Final: All gas appliances and equipment must be installed, connected and operational. All vent and flue connectors must be installed. The gas meter must be installed and protected, if necessary. All gas piping on the outside of the building that are not galvanized or copper must be corrosion protected (painted). All copper gas pipes must be marked.

Final Plumbing: All plumbing fixtures must be installed and properly working, all hot and cold water faucets must be operational. All drains must be installed and connected
