1

4 main types of pipes

Cast iron
-galvanized steel/iron
-copper
-plastic

2

Cast iron pipes

You will only find in drain systems
-heavy difficult to fit
-can join with pvc

3

PVC (plastic)

OD changes
-dimensions are referred to in schedules, 40, 60, 80 etc.
referencing wall thickness
-42-46 lbs of pressure should be in the line
-always prime with purple primer
-PVC is only for cold water

4

CPVC

-high temps and pressures
-hot and cold supply pipe
-slight yellow tint
3/8, 1/2, 3/4, 1" diameters

5

Copper

Rigid copper- best material ($$$)
- resists corrosion has smooth surfaces that provides best water flow

6

Types of copper

M- red lettering
L- blue lettering- usually req. by code
k- heaviest walls used mostly underground

7

Propane torch

DIY home projects, solders slower

8

Mapp Gas torch

Mixture of methylacetylene-propadine and liquified petroleum gas
- burns at 5300 degrees

9

Flux

the "purple primer" for soldering
cleans away the oxidized coating on metal and allows the liquid solder to flow and bond to the surfaces

10

make sure to have lead free solder wire

apply heat throughout process

11

To connect copper to galvanized pipe ...

you must have a dielectric union

12

Polyethylene (PEX)

-heating or cold water supply
-easy to install
-easy to transport
-good insulation
-quiet
-good for retrofitting
-freeze resistant
-multicolored. color does not indicate hot or cold line.
-need pex tool kit

13

PEX Code

-Max horz. supp. 32" and vert 10'
-w/stand 210 degrees for 48 hrs
-ongoing use is rated for 180 degress water up to 100lbs per sq inch of pressure

14

Push on tubing connectors

-snake, alligator, shark, etc bites will go on pex copper or cpvc but not PVC bc of the different ODs
-remove inner white sleeve when working with copper pipe

15

Drain waste vent system (DWV)

-system of pipes that carries water and waste to a sewer line or septic tank
-3 components --Drain lines- collect water from sink/shower
--waste lines- carry waste from toilets
--vent lines- exhaust sewer gases and provide the air pressure to allow wastes to flow freely

16

Key measurements

min 15" to L&R or toilet
min 12" to rear (recommended 13")

17

Vent piping

-Vent line must be at least 6" above the flood plane
-ea. drain line must be served by a vent line that carries sewer gases out through the roof.
- several vents may be connected together and joined
-any drain line must have 1/4" drop per foot

18

Vent size

-never less than 1.1/4"
-never be = or

19

Wet venting

connecting to another vent line within the critical distance

20

Aux venting

measuring to where the critical distance is and putting in a new vent line

21

direct venting

inside critical distance so you are connecting directly into main vent line

22

stack vent

where vent line exits the roof

23

soil stack vs waste stack

interchangeable terms

24

PVC drain system

-get measurements
-drill or saw hole
-dry fit
-apply hangers at 1/4" per foot drop
-prime/glue entire system together
-vent line out of roof through rubber footing

25

clean outs

-should be easily accessible
-y-shape fitting

26

P trap

goes from sink drain into wall

27

S trap

goes from sink drain into floor

28

Types of faucets

-compression
-disk
-cartridge
-ball

29

Ball faucet

single handle over done cap, 3 holes in ball for water hot and cold

30

Compression faucet

two handles, you can feel the rubber selling itself as you twist
