In this presentation we will learn various piping materials used in the plumbing, methods of connection and various fixtures used.

2.  PVC Pipes
 CPVC Pipe
 Copper Pipe
 PEX Pipe
 Galvanized Piping
 Glazed Stoneware Pipes

3.  By far the most commonly used pipe in residential
homes, polyvinyl chloride (PVC) pipe is the white
piping commonly used in plumbing applications.
Affordable and versatile with a number of different
fittings and sizes available, PVC is great for most
warm and cold water applications.
 PVC comes in two sizes, called “schedules.”
Schedule 40 is the typically used PVC type.
Schedule 80 has a slightly thicker wall.

4. Typically, you will use PVC for:
 Sink drain lines
 Toilet drain lines
 Bathtub drain lines
 Vent stacks
 Main water supply line running to the home
 High-pressure applications

5.  Chlorinated polyvinyl chloride pipes (CPVC)
are made from PVC that has extra chlorine
added to the material. It carries all of the
benefits of PVC with added durability. CPVC
will not degrade with hot water exposure and is
safe for drinking water. It is slightly more
expensive than PVC, however, and will split if
allowed to freeze.

6. CPVC is typically used for those applications
where PVC properties are wanted, but PVC is
not usable, including:
 Hot water delivery
 Drinking water delivery
 Hot water drains
 Waste and water disposal pipes

7.  Since the 1960s, copper piping has been the
standard for most home plumbing applications.
The long lifespan and durability of this piping
makes it an excellent choice for many applications.
It tolerates heat well and is extremely resistant to
corrosion. Copper does not degrade with water and
therefore is safe for use with drinking water.
 However, copper has one major drawback, and that
is the price.

8. In today’s homes, you will most often see copper
piping used for:
 Hot and cold drinking water supply
 Refrigerant lines for HVAC systems
 Other applications that require a tight seal
 Underground service lines

9.  PEX is an extremely flexible piping option that
can literally be snaked through a home and
bent around corners when needed. It requires
no glue and holds up better in freezing
conditions than CPVC because the materials
can expand and contract.

10. PEX pipe is great for:
 Retrofitting an older home
 Snaking through walls in a remodel
 Working in areas with low ventilation where
glue is dangerous

11.  Galvanized piping is steel or iron piping that
has been coated with zinc to help prevent rust
and corrosion.

12. Galvanized pipes are typically used in the
following applications:
 Water supply lines
 Outdoor applications
 Underground applications

13.  Stoneware is a vitreous or semi-vitreous ceramic
made primarily from stoneware clay or non-
refractory fire clay. Stoneware is fired at high
temperatures. The interior and exterior surfaces
of the pipes and fittings which remain exposed
after jointing, shall be glazed.

14.  Welding
 Threading
 Flanging
 Mechanical couplings
 PVC Adhesives

16.  Selecting pipe and piping materials involves
many factors. Designers should approach these
decisions and identify strengths and
weaknesses of various pipe materials and
connection methods.
