Dry vent

Is a pipe connecting several fixtures

Fixture branch

Is the drain from the trap of a fixture to the junction of that drain with any other drain pipe.

Fixture drain

Is a device located inside the tank for the purpose of maintaining water level for effective flushing of the water closet.

Flood Level

A metallic sleeve called or otherwise joined to an opening in pipe into which a plug is screwed that can be removed for the purpose of cleaning or examining the interior of the pipe.

Ferrule

Is a device located at the bottom of the tank for flushing water closets and similar fixtures.

Flush valve

Is a device which discharge a predetermined quantity of water to the fixture for flushing purposes activated by direct water pressure.

Flushometer valve

A branch vent that performs its function for two or more traps.

Group vent

Means any pipe or fitting which makes an angle of more than 45 degrees with the vertical.

Horizontal pipe

Is the lowest portion of the inside of any pipe or conduit that is not vertical.

Invert

Is the discharge from any fixtures, appliance or appurtenance in connection with a plumbing system which does not receive fecal matter.

Liquid waste

Is the same as circuit vent except that it loops back and connects with a stack vent instead of a vent stack.

Looped vent

In plumbing, it is a secondary pipe. In sewage, a common sewer to which no other common sewer is tributary. It receives sewage only from building sewer.

Lateral

Is a sewer line or system directly controlled by public authority.

Main sewer

Is the principal artery of the venting system to which vent branches may be controlled.

Main vent

Are installed receptacles, devices or appliances which are supplied with water, or which receives or discharges liquid borne waste, with or without discharge into drainage system which maybe directly or indirectly connected.

Plumbing fixtures

Is to provide circulation of air between drainage and vent systems.

Relief vent

Is a water supply pipe which extend vertically one full storey or more to convey water to branches or fixtures.

Riser

Is the installation of all parts of the plumbing system which can be completed prior to the installation of fixtures. This include drainage, water supply, vent piping and the necessary fixture supports.

Rough-in

The sewage containing human excrement and liquid household waste. It is also called domestic sewage.

Sanitary sewage

A sewer intended to receive sanitary sewage with or without industrial wastes and without the admixture of surface water, storm water or drainage.

Sanitary sewer

Is a Y connection used on fire lines so that two lines of hose maybe connected to a hydrant or to the same nozzle.

Siamese connection

A vertical pipe usually used for the storage of water, frequently under pressure.

Standpipe

Is a vent connecting to the drain pipe through a fitting at an angle not greater than 45 degrees or to the vertical.

Side vent

Is the vertical main of a system of soil, waste or vent pipe.

Stack

Is the extension of a soil or waste stack above the highest horizontal drain connected to the stack. It is sometimes called waste vent or soil vent.

Stack vent

Are underground drain pipes that receive sub-surface or seepage water only and convey it to a place of disposal.

Subsoil drain

A pit or receptable at a low point to which the liquid waste are drained

Sump

Is a fitting or device to designed as to provide when properly vented a liquid seal that will prevent the back passage of air without materially affecting the flow of sewage through it.

Trap

Is the maximum vertical depth of liquid that trap will retain, measured between the crown weir and top of the dip of the trap.

Trap seal

Is a vertical pipe installed primarily for the purpose of providing circulation of air to different part of the drainage system.

Vent stack

Is a pipe that conveys water from the water service pipe to the plumbing fixtures and other water outlets.

Water Distributing Pipe

Is the pipe from the water main or other source of water supply to the building served.

Water Service Pipe

Is a vent that receives the discharge from wastes other than water closet

Wet Vent

This type of pipe is most popular and generally specified material for drainage system in buildings. Buildings taller than 25 storey do not specify the use of this pipe because of constant vibrations which cause water leak of the pipe joints

Cast Iron Pipe

A type of cast iron pipe that is generally used for building installations

SV type

A type of cast iron pipe that is classified as extra duty piped used for underground installations

XV type

This type of pipe is made from alloy of cast iron and silicon. Widely used in chemical laboratories, industries and other installations where acid wastes are being discharge.

Acid Resistant Cast Iron Pipe

This type of pipe is made of asbestos fibers and Portland cement. Could be used as soil, waste, ventilation and downspout

Asbestos Pipe

This type of pipe is the cheapest among the sewer pipes. Sometimes recommended for house sewer and for septic tank installation. This type of pipe is light in weight, slightly flexible which could take slight soil movement without danger of cracking or pulling out from its joints but excessive hot water or chemical flow may soften or damage the pipe.

Bituminous Fiber Sewer Pipe

This type of pipe is one of the oldest materials used for sewer lines. Is highly resistant to most acid wastes. It is durable material for underground installations like public sewer, house sewer or storm drain.

Vitrified Clay Pipe

This type of pipe is one of the oldest plumbing materials used by the Egyptians, the Greeks and the Roman builders as soil and waste pipe. This type of pipe never used to convey water for human consumption because it is poisonous to human health

Lead Pipe

This type of pipe is made out from mild steel and easily corroded by alkaline and acid water

Galvanized Steel Pipe

This type of pipe is better in quality than the steel pipe for plumbing installation.

Galvanized Wrought Iron Pipe

This type of pipe is one of the most expensive types of pipe. Made of an alloy or zinc and copper mixed at 15% and 85% proportion respectively.

Brass Pipe

This type of pipe is a durable and extremely corrosive resistant material

Copper Pipe

This type of copper pipe is the heaviest and suitable for underground installation

This type of copper pipe is lighter than the K type and available in both the rigid and flexible form.

This type of copper pipe is the thinnest and available only in a rigid form.

This type of pipe was introduced in the Philippines at the early part of 70’s and developed in Germany in the mid-year of 1935.

Plastic or Synthetic Pipe

What type of plastic or synthetic pipe is Polyvinyl Chloride (PVC)?

Rigid type

What type of plastic or synthetic pipe is Polyethylene (PE)?

Flexible type

This type of cast iron pipe is used to a well-fitted hub and spigot connections

Standard Pipe

This type of cast iron pipe is recommended when the length of a pipe needed is more than 150 cm long wherein cutting is not necessary.

Single Hub

This type of cast iron pipe is preferred when a piece of pipe needed is shorter than 150 cm long. When the pipe is cut, both ends has hub to serve as joint connector.

Double Hub

This type of cast iron pipe is used in lieu of the single hub to do away with caulking of joints. It is cheaper and easily connected using a neoprene rubber sleeves.

Hubless Pipe
