Which is a WASH DOWN

Which is a REVERSE TRAP

Which is a SIPHON JET

Which is a SIPHON VORTEX

Areas in which all occupants

are ambulant and are able to move unaided

away from a fire. E.g. outpatient department,

service areas or zones

Areas which, because

of their construction or contents, contain huge

amount of combustible materials, thereby

constituting a fire load in excess of that

normally found. e.g. gas storage, linen closets.

Areas which, due to their

function are more usually susceptible to an

outbreak of fire, or to a rapid spread of fire or

smoke. E.g. kitchen , boiler room.

Areas in which persons

may reside and are not able to move unaided

away from a fire. E.g. – intensive care unit,

operating department.

Systems that have open

sprinklers, i.e. the heat sensing operating element

is removed during installation, so that all sprinklers

connected to the water piping system are open.

Water is not present in the piping until the system

operates. The piping is pressurized with air, at a

"maintenance" pressure which is relatively low

compared with the water supply pressure.

An automatic water supply provides water

under pressure to the system piping. All of

the piping is filled with water. Until sufficient

heat is applied, causing one or more

sprinklers to fuse (open), the automatic

sprinklers prevent the water from being

discharged.

Type of venting system where the vent connects with

a single fixture trap, usually at the back and

extends vertically and connects with a stack vent, a

vent stack or branch vent.

The extension to the open air of a soil or waste stack

above the highest horizontal branch drain or fixture

branch connected to the stack.

A vertical vent pipe installed primarily for the

purpose of providing circulation of air to

or from any part of the building

drainage system.

A branch vent which serves two or more traps

and extends from in front of the last fixture

connection of a horizontal branch to the vent stack.

Which is a GATE VALVE

Which is a ANGLE VALVE

Which is a CHECK VALVE

Which is a GLOBE VALVE

Vent used for underground public restrooms.

Vent used on fixtures which are located

in the room away from partitions that

might be utilized to conceal the waste

and vent

– A ___ vent is a method of

ventilation used rather extensively

for small groups of bathroom

fixtures

– A portion of the vent system

through which liquid wastes flow

- A vent without connection with the plumbing system

– It terminates at the roof and connected to the

fixture at point below the seat

Which are ELBOW fittings

Which is a UNION fitting

Which is a WYE fitting

Which are TEE fittings

A coupling is a pipe fitting used to stop leakages in broken or damaged pipes. The pipes to be connected should be of the same diameter. The two kinds of couplings used in plumbing are regular coupling and slip coupling.

This type of pipe fitting is almost similar to coupling in terms of functions, but just with a difference, i.e. a union can be removed easily any time while the coupling cannot. A variety of dielectric unions are used to join pipes made of different materials to avoid any kind of galvanic corrosion between them. These pipe fittings comprise of a nut, female and male ended threads.

Adapters are connected to pipes to either increase their lengths or if pipes do not have appropriate ends. These pipe fittings make the ends of the pipe either male or female threaded as per the need.

This pipe setting is used to reduce the flow size of the pipe from the bigger to smaller one. There are two kinds of reducers- concentric reducer and eccentric reducer. The former one is in the shape of a cone used for gradual reducing of the size of the pipe. The latter one has its one edge facing the mouth of the connecting pipe reducing the chances of air accumulation.

Which is a REDUCER

Which is a COUPLING

Which is a ADAPTER

Usually located along the entire perimeter of the roof.

Located every 8 to 10 meters & at every corner of the roof.

Drain designed to receive water collecting on

the surface of a roof and to discharge it into a

downspout. Designed to prevent clogging.

Downspouts should terminate in a catch basin (can serve more than one

downspout). Delivers water to the sewers in the street via gravity.

Solid organic matter that are denser than water and

settle at the bottom of the septic tank.

Liquid content of sewage

lighter organic material that rise to the surface of the

water

Bacteria found in the Septic Tank that can survive in places without

oxygen.

Bacteria found in the Septic Tank that relies on oxygen to survive.

Waste water with the exception of human wastes. From laundries, wash basins, sinks, and tubs, etc.

Waste water that contain solid and liquid human wastes.

Waste water that is only Rainwater.

Class _ fires involving solid materials such as wood, paper or textiles.

Class _ fires involving flammable liquids such as petrol, diesel or oils.

Class _ fires involving metals.
