extra duty; for underground installations (type of cast iron pipe)
XV TYPE
gained widespread acceptance after it has in many ways proven itself as superior material for cold water supply line and sewer
PLASTIC OR SYNTHETIC PIPE
`
two types of plastic pipes
- RIGID TYPE
- FLEXIBLE TYPE
the manufacturer of these commenced in australia in the 1950 and is now one of the most popular plastic pipe (flexible type)
POLYTHENE (PE)
this is form of plastic resin that was used extensively in the manufacture of water supply piping (flexible type)
POLYBUTELENE (PB)
is resistant to many acids (rigid type)
CHLORINATED POLYVINYL CHLORIDE ( CPVC)
has excellent chemical resistance (rigid type)
UNPLASTICIZED POLYVINYL CHLORIDE (UPVC)
is used for the conveyance of potable water
ACRYLONITRILE BUTADIENE STYRENE (ABS)
rubber pipes coated with styrene (rigid type)
STYRENE RUBBER PLASTIC (SR)
hard, lightweight, durable and extremely popular building material is the third most widely produced plastic pipes (rigid type)
POLYVINYL CHLORIDE (PVC)
polypropylene random copolymer with a pipe by extrusion ( rigid type)
polypropylene random
much lighter than concrete or metal
PVC pipes and fittings
straight and rigid cylindrical pipe
PPR pipes and fittings
refers to a metal planting process that coated iron or steel water
Galvanized iron pipes and fittings
most expensive
Brass pipes
durable and extremely corrosive resistant
Copper pipes
3 classification of copper pipes
- K type
- L type
- M type
heaviest; for underground (copper pipes)
K type
lighter; in both rigid and flexible form (copper pipes)
L type
thinnest; in rigid form (copper pipes)
M type
type of plumbing fixtures
- water closet
- lavatory
- bathtub
- bidet
- urinals
- kitchen sink
receptables intended to receive water, liquid or water-carried waste and discharge them into the drainage system
plumbing fixtures

3 sources of water
- rainwater
- natural surface water from streams and rivers
- underground water
combination of two chemical elements called hydrogen and oxygen
water
elements of water supply and distribution system
- water service
- riser
- distribution main
- fixture branches
- water meter
- valves and controls
- storage tanks
refers to the public water connection which are laid underground
water main
necessary to avert serious damages of the installation in case of service breakdown
valves
a valve in which the flow of water is cut off by means of sircular disc
gate valve
a valve in which the flow of water is cut off by means of sircular disc that fits against teh horizontal valve seat
globe valve
prevents the reversal flow of gas or liquid
check valve
operates in the same manner as the globe valve
angle valve
located at the lower end of a pump to prevent loss of priming the pump
foot valve
used on cold water systems, heating systems and other pipe lines with excessive pressure
safety valve
