Water Service Materials
ABS meaning
Acrylonitrile Butadiene Styrene
for
pressure-rated potable water use
Acrylonitrile Butadiene Styrene
water mains
ASBESTOS CEMENT PIPE
metallic, threaded pipe (Water
Service and Water Distribution)
BRASS PIPE
not used for individual
water supplies; “ductile pipe” for water mains
CAST IRON PIPE
copper pipe with or without
threads. Gray color code for water service use
COPPER PIPE
soft copper/rolls (water
service); rigid (water distribution)
COPPER TUBING
3 TYPES OF COPPER TUBING
Type M (thinnest)
Type L (middle (water service))
Type K (thickest)
white/cream colored plastic pipe for water
distribution
cPVC (Chlorinated Polyvinyl Chloride)
Meaning of cPVC
Chlorinated Polyvinyl Chloride
with threaded
fittings for water distribution; problem: rust
GALVANIZED STEEL PIPE
Meaning of PB
Polybutylene
rolled coils/straight lengths
PB (Polybutylene)
type of PB: water distribution pipe
Water service
type of PB: water service use
Blue color
type of PB: water service/water distribution
Gray color
Meaning of PE
Polyethylene
black/bluish for water
services
Polyethylene
drain/vent pipe
– white : CWL (Cold Water Line) only
PVC (Polyvinyl Chloride)
Meaning of PVC
Polyvinyl Chloride
Minimum working pressure of 100 psi/temp. 180 ºF
Pressure-reducing valve at the water service to
reduce the pressure to no more than 80 psi
WATER DISTRIBUTION PIPE
WATER DISTRIBUTION PIPES
- BRASS PIPE
- COPPER PIPE/TUBING
- GALVANIZED STEEL PIPE
- POLYBUTYLENE
once popular water distribution pipe
BRASS PIPE
more common choice water distribution pipe
COPPER PIPE/TUBING
rust-related
problems
GALVANIZED STEEL PIPE
ease of installation /
resistance due to splitting due to freezing
conditions / low cost
POLYBUTYLENE (PB)
Range from 1½” – 4” dia.
DRAIN, WASTE & VENT PIPE
DRAIN, WASTE & VENT PIPES
- ABS

- BOROSILICATE GLASS
- BRASS PIPE
- CAST IRON PIPE
- COPPER PIPE
- GALVANIZED STEEL PIPE
- LEAD PIPE
- POLYVINYL CHLORIDE
black/gray color/ Schedule 40 (used
above or below ground/joined by solvent-weld
cement)
ABS
above-ground use only /
joined by mechanical joints/coated to prevent
corrosive action
ALUMINUM TUBING
used above or below
ground/underground/heavy pipe schedule
BOROSILICATE GLASS
rarely used drain, waster, and vent pipe
BRASS PIPE
hub and spigot style
(joined by oakum/molten lead); hubless
(mechanical joints – rubber coupling)
referred as SOIL PIPE service weight pipe extra
heavy pipe
CAST IRON PIPE (CIP)
thin-walled/with yellow marking
/ time-consuming to install/used above/below
ground
COPPER PIPE
not to be installed
closer than 6” in to the earth
GALVANIZED STEEL PIPE
limited to above-grade installations
LEAD PIPE
white rating of Sch.40
solvent weld joint become brittle in cold weather for
BUILDING SEWER (ABS, CI, Vitrified Clay, PVC,
Concrete, Asbestos Cement)
POLYVINYL CHLORIDE
Interior / underground (for storm sewer)
STORM-DRAINAGE MATERIALS
STORM-DRAINAGE MATERIALS
- INSIDE STORM DRAINAGE
- SUBSOIL DRAINS
INSIDE STORM DRAINAGE
ABS, DWV
Copper, Type L Copper, Asbestos Cement, Cast
Iron, Vitrified Clay Brass, Galvanized, PVC, Type M
Copper, Type K Copper, Bituminized Fiber,
Concrete, Aluminum, Lead, Black Steel

the soil (Asbestos Cement, Vitrified Clay, Cast Iron
Bituminized Fiber, PVC, PE)
SUBSOIL DRAINS
PLASTIC PIPES TYPES
uPVC
PVC
cPVC
LDPE
HDPE
PP-R
PE-X
PB
electrical and telephone cables, sewer pipes and potable water supply .
uPVC
uPVC
Unplasticized Polyvinyl chloride
third most widely produced after PE and PPR. PVC is widely used
in construction because it is cheap, durable, and easy to assemble.
PVC
PVC
Polyvinyl chloride
thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin; hot and cold
water pipe, and industrial liquid handling
cPVC
cPVC
Chlorinated Polyvinyl chloride
used in sprinkler and drip irrigation systems, drainage systems, laboratories, industrial process lines,
agricultural piping, irrigation and many other public utilities.
LDPE
LDPE
Low Density Polyethylene
used water main schemes, potable water house connections, sprinkler and drip irrigation systems,
drainage systems, laboratories, industrial process lines, agricultural piping, irrigation
HDPE
HDPE
High Density Polyethylene
used in the manufacturing piping systems; both ones concerned with high-purity and ones designed
for strength and rigidity (use in potable plumbing, hydronic heating and cooling, and reclaimed
water); joined by heat fusion rather than gluing
PP-R
PP-R
polypropylene random copolymer
is a form of polyethylene with cross-links; hydronic radiant
heating systems, domestic water piping and insulation for high tension (high voltage) electrical
cables; used for natural gas and offshore oil applications, chemical transportation, and transportation
of sewage and slurries.
PE-X
PE-X
Cross-linked polyethylene
used in pressure piping, flexible packaging, water heaters, compounding and hot melt adhesives
