FIRECLAY: A variation of vitreous china having greater amounts of quartz and feldspar in the clay material beneath the vitreous surface. Fireclay is heavier (30%), denser, and thicker than regular clay. These properties insure smooth, flat surfaces on large fixtures which is not achievable with standard vitreous china.
GPM: (Gallons Per Minute) The rate of water flow by which faucets and showerheads are measured and regulated.
I.D.:
(Inside Diameter) All pipes are sized according to their inside diameter. IPS: (Iron Pipe Size) Standard pipe threads. Female IPS is internal pipe threads, male IPS are external pipe threads. Also known as “NPT” or “NPS”MALE IPS (MIP): (Male Iron Pipe) Standard external threads on pipe and fittings.
MIXING VALVE: Mixes hot and cold water to achieve a specified delivery temperature.
MOUNTING FRAME: External mounting means used to install sinks which have no integral provision.
NIPPLE: A short length of pipe installed between couplings or other fittings
NOMINAL SIZE: Size used for identification only; not literal dimensions.
O.D.: (Outside Diameter) The diameter of a pipe measured from the outside edge
POWDER COAT: A technique for applying paint to metal surfaces. The metal is covered with a powder of dry paint particles and is baked in an oven. This causes the powder to melt and harden into a tough, colorful finish.
PSI: (Pounds Per Square Inch) A means of measurement used to determine pressure within contained area.
PULL-OUT SPRAY: Single-control kitchen faucet which offers a retractable hose and sprayhead to be used for food preparation and cleaning.
PVD: (Physical Vapor Deposition) A modern plating process used mostly with polished brass or gold finishes on faucets. Vaporized zirconium reacts with nitrogen and another special gas to form a durable plated surface which will not tarnish or discolor.
RISER: A vertical metal or plastic tube or assembly that connects a faucet to the water supply stop valve. Usually made of copper.
ROUGH-IN:
Installation of the drain, waste, vent, and supply lines in a structure to the proposed location of each fixture.SELF-RIMMING: A style of bathroom lavatory or kitchen sink with a rolled and finished edge, or rim. The fixture installs on top of a counter without the need for a metal sink rim.
STOP: The shutoff valve under sinks and toilets. Allows water supply to be cut off to one fixture without affecting the water supply to the entire house or building.
TEE: T-shaped fitting with three openings that allow another pipe to be joined at a 90 degree angle, used to create branch lines.
TRAP: Curved section of drain line that prevents sewer odors from escaping into the atmosphere. All fixtures that have drains must have a "P” trap installed. A toilet is the only plumbing fixture with an “S” trap.TRIM KIT:
Refers to the outside decorative covering of a faucet rough-in valve. Includes items such as the showerhead, tub spout, handles, etc. The trim is the parts you can see when looking at a faucet.UNDERMOUNT: A style of sink which is positioned under the cutout of the countertop.
