ABS:

Generally, in the plumbing industry (it is used a lot in the auto industry because it is so durable) this is

black colored plastic pipe and fittings used in drainage, sewer, waste and vents. ABS (Acrylonitrile

Butadiene Styrene) pipe/fittings and alsoPVC (see below) plastics have replaced much of the cast iron,

lead and steel pipes formerly used for DWV. Important note is that no solvent cement (and primer) can

totally "glue" (solvent weld) ABS to PVC plastic. Under normal conditions, quality ABS (when virgin

resins are used) will not crack, chip or peel.

ACRYLIC:

A thermoplastic used on the surface of bathtubs and whirlpools. Generally comes in sheets and is formed

to the shape of the mold (tubs/showers) in the factory. Generally fiberglass is added to the back for

strength.

ADA:

Governmental guidelines. ADA stands for Americans with Disability Act. These guidelines do tend to

change over time. When related to public plumbing, kitchen and bath the intent of the act/rules is to

make restrooms, and other public sanitary facilities more easily accessible to those who have some

disability such as being blind. Braille signs and grab barsare just two examples of products that we sell

largely due to ADA rules.

ADAPTOR:

A fitting that joins two different types of pipes together. Or/Also a fitting that joins threaded with none

threaded pipe (as in: female adaptor or male adaptor).

AGA:

Imprinted on many gas valves and appliances. It is the American Gas Association rating.

2/24

A mechanical one way valve used in place of traditional non mechanical (very reliable) vents. It is to

allow air to enter waste piping and equalizing pressures. Vents are used to preserve the seal of trap in

plumbing fixtures. Also known as auto trap vents.

AIR GAP:

Air-filled space allowing contaminated water to discharge freely, preventing the contaminated waterfrom ever siphoning back into the potable water supply.

ANGLE STOP:

An "emergency" stop (valve) that is usually installed before the water supply line (below) to toilets and

faucets. Angle stops are to be shut off in case of an emergency or repair and are generally not designed

for daily on and off usage. The difference between a "straight stop" and an "angle stops" is that the

"angle" stop changes direction by 90 degrees while a straight stop is like most valves and does not

change direction.

ANODE ROD:

Sacrificial rod used mainly in water heaters. It helps protect the lining of and generally lengthens the lifeof a water heater.

BALLCOCK:

Also known as a float valve, the ballcock controls the flow of water into a gravity-operated toilet tank.

When the toilet is flushed the float ball drops with the water level causing the ballcock to open, this

allows water to reenter the tank. As the water level rises it lifts the float ball causing the ballcock to close

once the tank is completely filled.

BALL PASSAGE:

The ball passage indicates the size of a ball that can pass through a toilet's trapway. It also refers to the

size of the trapway of a toilet; the trap size is to be 1/8" larger than the ball that can pass through it.

BASIN:

Generally circular, vessel with slopping or curving sides for holding water for washing.

BASKET STRAINERS:

Generally a basket shaped strainer drain receptacle with holes, for sinks. Used to catch large food

particles to prevent them from entering the drainage system.

BIBB:

aka bibcock or hose bibb - typically a faucet with nozzle bent downward. Also called: outside/outdoor

faucet/spigot or garden faucet.

BIDET:

Pronounced B'Day, is a plumbing fixture similar to a toilet bowl (but no solids are to be deposited in a

bidet) used for washing genitals and posterior areas of the body. It is floor mounted, usually next to a

toilet, and incorporates a washing basin, faucet and sprayer. Bidets are very popular in some countries

such as France and have finally been "discovered" in the U.S.. A bidet is commonly equipped with a hot

and cold mixing valve to provide warm water for washing.

brand, you could be ordering replacement hoses frequently.

PVC:

Polyvinyl Chloride is used today for cold water piping (outside/underground) as well as for sewers,

drains, wastes and venting pipes and fittings. Flexible PVC pipe is also available and quite practical for

REFILL TUBE:

Carries water from the ballcock to the overflow tube after the siphon break in order to refill the toilet

bowl.

RIM HOLES:

Small holes along the underside of the toilet bowl rim in which water flows out of, resulting in a rinsingof the toilet bowl's inner surface.

RISER:

A vertical assembly of pipe and fittings that generally distributes water upward.

bowl.

SCHEDULE (SCH):

The "Schedule" designation tells you how thick the wall is for any size of pipe with the higher schedule

numbers meaning a thicker wall. The most common schedules are Sch 40 and Sch 80, but the actual wall

thickness varies depending on the size of the pipe.

SIPHONING:

Suction that takes place when water pressure drops which causes water or waste to be pulled through a

descending outlet channel.

SIPHON BREAK:

Recognized by the gurgling sound that takes place at the end of a toilet flush, the siphon break is when

air is re-introduced into the trapway, causing the siphoning action to cease.

SDR:

Standard Dimension Ratio (SDR) used for determining the minimum wall thickness for pipe. SDR is

found by dividing the outside diameter (OD) of the pipe by the wall thickness measurement. To find the

Toilet. Many in our industry will write w.c. on drawings or quotes which means water closet (aka:

"toilet").

WATER HAMMER:

Shock waves in plumbing generally due to high velocity water being shut off quickly. This is mainly

caused by undersizing of pipes and faucets or valves that are shut off fast. Sometimes installingwater

hammer arrestors can help alleviate or lessen water hammer. Best is to increase water pipe sizes (thereby

slowing velocity).

WHITE - EURO:

Not all whites are alike. Euro-white generally is a somewhat yellowish white. Similar to Corian and

Avonite's = Cameo white; Surell/Formica and Wilsonart's = Frosty white.

WHITE - POLAR:

Polar-white generally is a bluish white. Similar to Kohler, Elkay, Moenstone, and Swanstone's = White;

Corian's = Glacier white; Avonite's = Porcelain white; Surrell/Formica's = Arctic white.

WIDESPREAD:

A style of bathroom lavatory faucet having separate spout and handles. Usually 8" from center of

handle-to-handle. Some widespread faucets can be set with handles up to 12" apart.

WORKING PRESSURE:

Normal, maximum operating pressure design of a faucet, valve or plumbing product.

CONSOLE LAV: A table-like fixture with an integral lavatory. The back is fixed to awall and the front is supported by consoles (brackets) or legs.

COUPLING: A fitting that joins two pieces of pipe (or other fittings) together.

CPVC : Chlorinated PolyVinyl Chloride is a plastic product designed for

drinking water at temperatures up to 180 degrees (where code

permits). Comes in straight or rolls, generally off white colored

(orange for fire sprinklers). .

CWP: Abbreviation for cold working pressure.

CWT: Abbreviation for Copper Water Tube (refers to nominal pipe size).

DIVERTER: Valves which direct water to various outlets. They are used in

showers, tub & shower combinations, bidets, Roman tub fillers and

kitchen faucet sprayers.

DRAIN: Drainage inside the building, note that "sewer" is outside the

building.

DWV: Abbreviation for Drainage, Waste & Vent systems. Not for drinking
