Engutil 2 Module 1 Flashcards
The word “PLUMB” is originated from the Latin word which means “Lead” as Lead
pipes are the first effective pipes used during Roman Era.
“PLUMBUM”
the system of pipes, fixtures and other apparatuses installed for the distribution of
potable water for drinking that can be use for drinking, heating and washing, and waterborne
waste removal.
Plumbing
is the art and technique of installing pipes, fixtures and other apparatuses in buildings
for bringing in the supply, liquids, substances and/or ingredients, and removing the; and such
water, liquid and other carried wastes hazardous to health, sanitation, life, property; also the
pipes and fixtures after installation i.e., the plumbing system. (Section 217.6 The Revised National
Plumbing Code of the Philippines 1999)
Plumbing
includes all potable water supply and distribution pipes, all plumbing fixtures
and traps; all sanitary and storm drainage systems; vent pipes, roof drains, leaders and

downspouts; and all building drains and sewers, including their respective joints and connections;
devices, receptacles, and appurtenances within the property; water lines in the premises: potable,
tap, hot and chilled water piping; potable water treating or using equipment; fuel gas piping;
water heaters and vents for same. (Section 217.12 The Revised National Plumbing Code of the

Plumbing Systems
In summary, Plumbing systems is:
- Water Supply and Water Distribution
- Plumbing Fixtures
- Drainage Systems
A plumber-in-training and a helper to a journeyman. Usually
practices the plumbing trade for 3-5 years.
Apprentice Plumber
A plumber that is able to finish his apprenticeship and is able to
install/repair/alter the plumbing system.
Journeyman Plumber
A plumber that is technically and legally qualified, and licensed ti
practice the profession of Master Plumbing without limitations.
Master Plumber
A physical separation, it can be a low inlet into indirect waste receptor from the
fixture, appliance, or device indirectly connected.
AIR BREAK
Unobstructed Vertical Distance through free atmosphere between the lowest opening
from any pipe, plumbing fixture, appliance or appurtenance conveying potable water or waste to
the flood level rim of the receptor.
AIRGAP
The flow of water or other liquids into the distributing pipes of a potable supply of
water from any source other than its intended source.
BACKFLOW
occurs due to increased reverse pressure above the supply
pressure. Often cause by pumps, broilers, gravity or other sources of pressures.
BACK PRESSURE
the flowing back of used, contaminated, or polluted water from a plumbing
fixture into water supply pipe due to negative pressure in such pipe. (Negative Pressure-Back
flow)
BACK SIPHONAGE
Any two or more similar adjacent fixtures when discharge into a common
horizontal soil or waste branch.
BATTERY OF FIXTURE
any part of the piping system other than a main, riser or stack
BRANCH
a vertical shaft for installation of different pipe stacks.
CHASE
unless specifically stated, the term “diameter’’ is the nominal diameter as designated
commercially. I. D. denotes inside diameter of pipe and O.D. denotes outside diameter of tube.
DIAMETER
a receptacle other than a trap attached to a plumbing system in which water or wastes may be
collected or retained for ultimate discharge into the plumbing system.
FIXTURE
- is an arbitrary quantity in terms of which the load producing effects or water requirements
on the plumbing system of different kinds of plumbing fixtures are expressed in some arbitrarily chosen
scale. One fixture unit is equivalent to a rate of flow at 28.3 liters per minute ( 1 cu. ft./minute).
FIXTURE UNIT
-is the top edge of a receptacle from where water overflows.
FLOOD LEVEL RIM
is any pipe or fitting installed in a horizontal position or which forms an angle of not
more than forty-five (45) degrees with the horizontal plane.
HORIZONTAL PIPE

any one of a special class of device or equipment intended to perform a special
plumbing function. Its operation and/or control may be dependent upon one or more energized
components, such as motors, controls, heating elements and pressure-temperature-sensing elements.
PLUMBING APPLIANCE
a manufactured device or a prefabricated assembly or an on-the-job
assembly of component parts, and serves as adjunct to the basic piping system and plumbing fixtures. An
appurtenance demands no additional water supply nor does it add any discharge load to a fixture or the
drainage system. It performs some useful functions in the operation, maintenance, servicing, economy or
safety of the plumbing system.
PLUMBING APPURTENANCE
are approved-type installed receptacles. devices or appliances supplied with water
or receive liquid or liquid-borne wastes and discharge such wastes into the drainage system to which they
may be directly or indirectly connected.
PLUMBING FIXTURES
- a water supply pipe, which extends vertically to one full story or more to convey water into pipe
branches or plumbing fixtures.
RISER
the installation of all piping and fitting parts of the plumbing system, which can be
completed prior to the installation of fixtures and accessories. These include sanitary and storm drainage,
tap, hot and chilled water supplies, gas piping, vent piping and the necessary fixture supports.
ROUGHING-INS
- of a building or premises consists of the water service pipe,
water supply line, water distributing pipe and the necessary branch pipes, fittings, valves and all
appurtenances required for the supply of potable water.
WATER SUPPLY/DISTRIBUTION SYSTEM
- a pipe which conveys potable water from the building supply pipe to the
plumbing fixtures and other water outlets.
WATER- DISTRIBUTING PIPE
or street main is the water-supply pipe for public or community use.
WATER MAIN
the system of reservoirs, channels, mains, and pumping and purifying equipment by which
a water supply is obtained and distributed (as to a city).
WATERWORKS
- includes all the piping within public or private premises which convey sewage or
other liquid wastes to a legal point of disposal but does not include the mains of a public sewer system or a
public sewage treatment or disposal plant.
DRAINAGE SYSTEM
that part of the lowest horizontal piping of a drainage system which receives the
discharge from soil, waste and other drainage pipes inside the walls of the building and conveys it to the
building sewer beginning 0.6 meter outside the building wall.
BUILDING DRAIN
that pat1 of the horizontal piping of a drainage system which starts from the end of the
building drain and which receives the discharge of the building drain and conveys it to a public sewer,
private sewer, individual sewage disposal system or other point of disposal.
BUILDING SEWER
