CHAP 2 E-I Flashcards
–is the minimum cross-sectional area at the point
of water supply discharge measured or expressed in terms of: ( 1) diameter of
a circle; (2) if the opening is not circular, the diameter of a circle of
equivalent cross-sectional area. (This is applicable also to air gap
installation.)
EFFECTIVE OPENING
the on-going installation of the plumbing system or
any part thereof which has been installed prior to the effectivity of this Code.
EXISTING WORK
one person living alone or a group Jiving together, whether related to each other by birth or not.
FAMILY
a valve located at the end of a water pipe through of which water
can be drawn from or held within the pipe .
FAUCET
a metallic sleeve, caulked or joined to an opening in a pipe,
into which a plug is screwed that can be removed for cleaning or examining
the interior of the pipe.
FERRULE
- 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
the water supply pipe between the fixture supply pipe and the water-distributing pipe .
FIXTURE BRANCH
the drainpipe from the trap of a fixture to the junction
of that drain with any other drainpipe.
FlXTURE DRAIN
a water supply pipe connecting the fixture with the
fh.ture branch.
FIXTURE SUPPLY
is an arbitrary quantity in terms of which the loadproducing efTects or water requirements on the plumbing system of different
kinds of plumbing fixtures are cxpres~cd in some arbitrarily chosen scale.
One fixture unit is equivalent to a rate of flow at 28.3 liters per minute ( l cu.
ft./minute).
FIXTURE UNIT
the level in a fixture at which water begins to overflow
ovc:r the top or rim of the fixture.
FLOOD LEVEL
Is the top edge of a receptacle from where water
overflows.
FLOOD LEVEL RIM
- a fixture is flooded when the liquid therein rises to the flood
level rim.
FLOODED
the area included within surrounding walls of a building
(or portion thc1eof), exclusive of vent shafts and courts.
FLOOR AREA
- a tank located above or integral with water closet, urinal or
similar fixtures for flushing or removing excrements in the fixture.
FLUSH TANK
is a device located at the bottom of the tank for the
purpose of flushing waster closet and similar fixtures.
FLUSH VALVE
- is integrated within an air accumulator vessel which is designed to discharge a predetermined quantity of water into
fixtures for flushing purposes.
FLUSHOMETER TANK
is a device, which discharges a predetennined
quantity of water into fixtures for flushing purposes and is actuated by direct .
water pressure.
FLUSHOMETER VALVE
- a valve in which the flow ofwater is cut off by means
of a circular disc fitted against machine-smoothed faces, at righl angles to
the direction of flow. The disk is raised or lowered by means of a
threaded stern connected to the handle of the valve. The opening in the
valve is usually as large as the full bore of the pipe.
GATE VALVE
a valve in which the flow of fluid is cut off by means of
a circular disc that fits over and against the horizontal valve seat. The
movement of the plane of disc is parallel to the nonnal direction of flow of
water through the orifice resulting to a tortuous passage which offers a high.
pressure loss.
GWBE VALVE
a return bend of small-sized pipe, one end of which is
about 30 em. long and the other end is about 7. 5 em. long. It is commonly
used as a faucet for a pantry sink. Also, the term means the flexible tubing
connection between a service pipe and a water main.
GOOSENECK
is the slope or fall of a line of pipe with reference to a horizontal
plane. In drainage, it is usually expressed as the fall in centiEleters per
meter or percentage slope of pipe.
GRADE
an interceptor of at least 3 c.ubic meters
capacity to serve one or more fixtures and which is remotely located.
GREASE INTERCEPTOR
a device designed to retain grease from one to a maximum of tour fixtures .
GREASE TRAP
the water that stands in or passes through the ground .
GROUND WATER
a branch vent that performs its functions for two (2) or
more traps.
GROUP VENT
see Supports.
HANGERS
- the vertical distance from the “Grade Line” to the highest point of the coping of a tlat roof or to the top line of n :”J1?.<itt
roof or to the average height of the highest gable of a pitch or hip-roof
HEIGHT OF BUILDING
see Contamination.
HIGH HAZARD -
- is a drain pipe extending laterally from a soil or waste stack or building drain with or without vertical sections or
branches, which receives the discharge from one or more fixture drains and
conducts it to the soil or waste stack or to the building drain.
HORIZONTAL BRANCH
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
is that part of the lowest horizontal piping of a plumbing
system which receives the dischaiges from soil, waste and other drainage
pipes inside of a building and conveys it to the house sewer outside of the
building.
HOUSE DRAIN
is that part of a plumbing system extending from the
house drain at a point 0.60 meters from the outside face of the foundation
walt of a building to the junction with the street sewer or to any point of
discharge, and conveying the drainage of one building site.
HOUSE SEWER
is the pipeline from the building to the public or street storm drainage system
HOUSE STORM SEWER
are cast iron soil pipes with plain ends connected
together with bolted stainless steel bands and neoprene gaskets.
HURLESS PIPES
is a pipe that does not connect directly with the drainage system but conveys liquid wastes by discharging into a
plumbing fixture, interceptor or receptacle directly connected to the
drainage system .
INDIRECT WASTE PIPE
is a pipe installed to vent a fixture trap and which collects with the vent system above the fixture se1ved or terminates in the open air.
INDIVIDUAL VENT
any and aJI liquid or water-borne waste from
industrial or commercial processes, except domestic sewage.
INDUSTRIAL WASTE
I.P.S.
means Iron Pipe Size
a condition contrary to sanitary principles or injurious to
health .
INSANITARY
is a device designed and installed to
separate and retain deleterious, hazardous or undesirable matters from
normal wastes and permits normal sewage or liquid wastes to discharge into
the disposal terminal by gravity.
INTERCEPTOR (CLARIFIER)
I
The lowest portion of the interior part of any pipe or conduit that is not vertical.
