1. Plumbing Unit

4. Purpose:
Transporting liquids safely from one point to another for storage, processing, and direct use
Carries fresh water from a source like a well to a fixture.
A drain waste vent carries waste water away to septic tank.

5. Terminology Pipe: round/hollow RIGID material
Tubing: round/hollow FLEXIBLE material
Fitting: connecting device
Joins two piece of pipe
Connects a piece of pipe to a fixture, pump

6. Pipe Size Pipe size is represented by the inside diameter
Pipe wall thickness (grade) is represented by a ‘schedule #’
- greater number represent greater strength
- Ex:

7. Plastic Pipe
PVC – (polyvinyl chloride) used mainly for cold water supply, drain waste vents, or irrigation lines
What you’ll use in this class!

8. Pipe Fittings Elbow fitting: changes angle/direction of pipe
Tee fitting: allow for branched lines

9. Pipe Fittings
Male/Female Adapters: used to change the end of a non-threaded pipe

10. Pipe Fittings Reducer: used to change diameter of pipe
Plug: close an opening that is re-opened regularly
Cap: closes end of dead end pipe

11. PVC Pipe Tools Hacksaw: used to cut pipe to length.
Teeth should be pointing forward
Cut forward, slight downward angle

12. PVC Pipe Tools Pipe Cutter: used to cut pipe to length.
Ratchet cutting
Only use on PVC to keep blade true

13. Primer Purposes: clean surface of the pipe
purple color - easily seen by inspector
Prepares pipe surface for bonding with glue = water tight seal

14. Glue Provides sturdy/water tight seal when combined with dried primer
Dries and sets fast!

15. Step 1: Primer pipe and fittings

16. Step 2: After primer dries, apply glue to pipe and fittings

17. Step 3: Quickly connect pipe to fittings. Seat all the way into fitting!

18. Things to avoid: Forgetting primer
Dripping primer down pipe (excess primer)
Excess glue
NOT seating pipe all the way into socket before glue dries

19. Copper Pipe Used in water supply and waste drainage vent systems
Thin walled – used for home plumbing
Color Coded Red
What you’ll use in this class!

20. Copper Pipe Easy to work with, but more expensive than PVC
Solder joints together instead of gluing

21. Copper Pipe Tools Tubing Cutter: Used to cut pipe to length
Even/straight cuts & reaming tool
Tighten a bit at a time, rotating around pipe

22. Copper Pipe Tools Copper Fitting Brush:
Used to clean inside diameter of fittings
