4. Plumbing Unit Plumbing Unit

5. Plumbing…What is it? Plumbing is the installation and repair of water pipes and fixtures including pipes for handling wastewater and sewage Plumbing is the installation and repair of water pipes and fixtures including pipes for handling wastewater and sewage Latin word plumbum meaning lead Latin word plumbum meaning lead Pipes are rigid tube-like materials Pipes are rigid tube-like materials Fittings connect pipe to pipe or other objects to pipes Fittings connect pipe to pipe or other objects to pipes Flexible pipes are called tubing Flexible pipes are called tubing

6. What is a plumbing system? Plumbing includes all the piping and fixtures that provide water for drinking, cooking, bathing, and laundry; as well as a means of disposing of wastewater.

7. Putting in a plumbing system takes a lot of thought…………………. When a house is being built, plumbers and carpenters must work together so the frame of the house is prepared for plumbing to be put in.

8. Plumbing can be dangerous, so there are codes that must be followed in order to keep everyone safe. A code is a set of rules that can be enforced by law!!!

9. Codes Why is it important to follow codes? If it is not up to code it will not pass inspection and will have to be torn out and redone becoming very costly. If it is not up to code it will not pass inspection and will have to be torn out and redone becoming very costly. If it is poorly designed then it will not work well and owner will be unsatisfied. If it is poorly designed then it will not work well and owner will be unsatisfied. Could cause wastewater to mix with potable water if not installed properly. Could cause wastewater to mix with potable water if not installed properly.

10. There are 2 Types of Plumbing Systems 1) Water Supply System 2) Drainage, Waste, and Venting (DWV)

11. Water Supply System Distributes water under pressure throughout the structure for drinking, bathing, cooking, and laundry. Distributes water under pressure throughout the structure for drinking, bathing, cooking, and laundry. This is a 2 pipe system. This is a 2 pipe system. One pipe carries cold water, and the other hot water. One pipe carries cold water, and the other hot water.

12. DWV Carries away wastewater and solid waste from bathrooms, kitchens, and laundries. Carries away wastewater and solid waste from bathrooms, kitchens, and laundries. This subsystem is not under pressure, and must be properly vented to prevent wastewater form entering the drinking water supply. This subsystem is not under pressure, and must be properly vented to prevent wastewater form entering the drinking water supply.

13. Pipe Sizing Pipe is usually identified by the Nominal size (I.D. and O.D.) Pipe is usually identified by the Nominal size (I.D. and O.D.) Common sizes include ¼”, ½”, ¾”, 1”, 1and1/2”, 2” Common sizes include ¼”, ½”, ¾”, 1”, 1and1/2”, 2”

14. Different Types of Pipes and Tubing Chlorinated Polyvinyl Chloride (CPVC) Chlorinated Polyvinyl Chloride (CPVC) Polybutylene (PB) Polybutylene (PB) Acrylonitrile Butadiene Styrene (ABS) Acrylonitrile Butadiene Styrene (ABS) Polyvinyl Chloride (PVC) Polyvinyl Chloride (PVC) Black Steel or Galvanized Black Steel or Galvanized Copper Tubing Copper Tubing Ceramic Ceramic

15. Chlorinated Polyvinyl Chloride (CPVC) Plastic Supply Piping Plastic Supply Piping Buff colored thermoplastic Buff colored thermoplastic Light, easy to handle, resists cracks Light, easy to handle, resists cracks Good for freezing conditions Good for freezing conditions Suitable for piping hot water Suitable for piping hot water Rating of 180 degrees Fahrenheit and 100 psi Rating of 180 degrees Fahrenheit and 100 psi

16. Polybutylene (PB) Plastic Supply Piping Plastic Supply Piping Flexible, allowing for easy installation Flexible, allowing for easy installation Connections made with compression fittings Connections made with compression fittings Also called “Pex” Also called “Pex”

17. Acrylonitrile Butadiene Styrene (ABS) Plastic Piping Plastic Piping Resists chemical attack Resists chemical attack Inexpensive Inexpensive Joined with a one-step solvent Joined with a one-step solvent Used commonly for sewage and underground applications Used commonly for sewage and underground applications

18. Corrugated and Perforated Pipe Used in drainage systems

19. Polyvinyl Chloride (PVC) Plastic Piping Plastic Piping Has lower thermal expansion that makes long runs easier to control Has lower thermal expansion that makes long runs easier to control Joined with a two-step primer/solvent and suitable fittings Joined with a two-step primer/solvent and suitable fittings Usually used for cold water applications Usually used for cold water applications

20. Black Steel and Galvanized Very strong Very strong Not used much anymore Not used much anymore Wall thicknesses include standard, extra heavy, and double extra heavy Wall thicknesses include standard, extra heavy, and double extra heavy

21. Copper Tubing Available in soft, annealed, or rigid form Available in soft, annealed, or rigid form Resists corrosion very well Resists corrosion very well Very expensive Very expensive Creates a bad taste if water is acidic Creates a bad taste if water is acidic May leave stains on valves, faucets, fixtures, and appliances May leave stains on valves, faucets, fixtures, and appliances Wall thicknesses include K (thickest), L, M Wall thicknesses include K (thickest), L, M

22. Ceramic Pipe Historically used for drainage and sewer systems Historically used for drainage and sewer systems Gravity fed Gravity fed New technology has allowed them to be used in industrial systems New technology has allowed them to be used in industrial systems Reinforced with silicon carbide Reinforced with silicon carbide Hard, wear-resistant Hard, wear-resistant Excellent thermal conductivity Excellent thermal conductivity

23. What are the differences between valves, fixtures, faucets, and fittings?

24. Valves Devices that control the flow of water in the water supply system. They are installed at certain places on the lines so that water can be shut off easily.

25. Faucets Valves that permit controlled amounts of water as needed for use in a building. They deliver water to sinks, showers, and bathtubs, but can also deliver water to a hose or bucket.

26. Fixtures Water-using devices such as sinks, bathtubs, urinals, stools, showers, and water heaters. They are attached to the plumbing system and receive water from the supply system.

27. Fittings Used to connect pipes of similar or different types Used to connect pipes of similar or different types Adaptors = connect different types of pipes Adaptors = connect different types of pipes Reducers = connect different sizes of pipes Reducers = connect different sizes of pipes Elbow = used for single direction change Elbow = used for single direction change Tee = used for splitting a line into 2 directions Tee = used for splitting a line into 2 directions

28. Fittings Coupling = connects 2 similar types of pipes Coupling = connects 2 similar types of pipes Union = connects 2 similar types of pipes and can be opened later Union = connects 2 similar types of pipes and can be opened later Plug = used to close a fitting Plug = used to close a fitting Cap = used to close a pipe end Cap = used to close a pipe end Nipple = a short piece of pipe Nipple = a short piece of pipe
