Looking around the American Standard website or at a brochure and see a term you’re not familiar with? You’ll probably find it here.
Actuator Button: Located on the left side of the tank or in center of tank cover. Lever or button is depressed to activate flushing cycle.
Adjustable Hot Limit Stop: Restricts hot water output in single control faucets and showers to protect against scalding by limiting the swing to the hot side.
Apron: An acrylic panel can be used in place of tile or marble. When an acrylic tub is mounted in a 3-wall installation.
Back-to-Back Cartridge: For use when you have two bathrooms showers back to back. This cartridge keeps you from having to replumb your hot & cold supply lines in one of the showers (it internally has hot & cold reversed).
Ballpass: A method of measuring trapway or outlet size.
Bidet: A personal hygiene fixture with hot and cold water supply intended for genital and personal cleanliness.
Centerset: Area measuring 4" from the center of left faucet handle to center of the right handle.
Conical Sponge Washer: Sealing washer on a urinal between outlet connection at the wall and the china to make a watertight seal.
CWT: Copper Water Tube.
Faucet Trim: All of the decorative parts to your faucet, such as handles, wall plate, spout, etc.
Female Threads: The threads of the pipe are on the inside.
Fixture: China piece only, without trim and/or fittings.
Flapper: Disc-like composite rubber seal that retains water in a toilet tank. During the flushing cycle, it is lifted to release water from the tank into the toilet bowl for a complete flushing cycle.
Floor Flange: Cast iron, PVC, ABS or metal ring located flush to the floor and is connected to the drain pipe which the toilet is fastened to. (Offset floor flange allows waste pipe to remain at existing rough but will move flange out approximately 2".)
Flush Tower: Patented American Standard tower that releases water into the bowl. This patented innovation provides the most powerful flush possible while using precisely 1.6 gallons of water. There’s no chain and flapper, so there’s no more jiggling the handle.
Flush valve: A special form of valve located at the bottom of a toilet tank, used to discharge the water from the tank into a water closet or urinal.
Flushometer valve: System used in our pressure assisted toilets Air trapped inside an enclosed tank is compressed as water refills the tank after it is flushed.. When the toilet is flushed, the air releases like a tightly wound spring, surging the water into the bowl at high velocity. The crest of this torrent empties bowl contents in less than 4 seconds, and pushes them through the drainline.
Gravity Fed Toilet: Water in the tank is quickly released into the bowl and its weight and gravity create a siphonic action to withdraw waste and water from the bowl.
Inlet Spud: Located on top of the china. It is the connection from the flush valve to feed the water to the urinal or commercial toilet. A water supply tube fits inside the inlet spud, and a compression nut is secured on top to make a watertight connection. An escutcheon covers the compression nut and inlet spud.
Integral: A cast or formed part of a fixture, such as seat or tank.
IPS: Iron Pipe Supply
Male Threads: The threads of the pipe are on the outside.
Neoprene gasket: Used instead of wax ring on rear outlet installations as a seal to prevent leakage and fumes. (A wax ring will soften and may cause drip-down leakage and escape of fumes).
Nominal Dimension: Within established range of manufacturing tolerances.
NPT: National pipe threads
One Hundred Seventy C Kit: Kit which bolts the toilet tank to the toilet bowl (gasket, two bolts, washers and nuts).
One Piece Toilet: Tank and bowl are molded together into one piece, not separate tank and bowl.
Outlet Connection: Waste connection to the drain system.
Plunger Repair Kit: Depending upon model-may contain plunger, clip, seat, o-ring to seal top of water control to body of water control. If the float rod is lifted up and the water keeps running, using a Plunger Repair Kit may stop water from running in the tank via the refill tube. Newer models do not have a plunger repair kit option, as it is relatively inexpensive to replace the entire water control.
Pressure Assisted Toilet: Utilizes the power of the flushometer valve to create a powerful siphonic flushing action. Water fills a sealed tank inside the chinaware tank creating pressure by displacing air within this sealed tank. When the push button or trip lever is activated, the water, under pressure, rapidly thrusts or pushes waste and water through the bowl. The entire flushing process occurs very quickly (about 4 seconds).
Pressure balance: Pressure balanced shower valves protect you from drastic temperature changes should someone flush a toilet while you are in the shower.
Pressurized flushing device: A product that uses the force contained within the water supply to create a pressurized discharge to flush fixtures and which is exclusive of gravity type flushing systems. Flushometer valves and flushometer tanks (pressure assist) are examples of pressurized flushing devices.
PSI: Pounds per square inch. Measures the pressure of the water supply as it enters a building.
Refill tube: Outlet of water control. It is what the water goes through to fill the tank.
Screwdriver Stops: Shut off valves built into the brass body of the bath/shower unit (if you need to work on the unit you turn the water off at the body instead of shutting off your whole house.)
Seam Cover: Used with several Stallbrook urinals installed side by side to create a seamless appearance. It is installed between each fixture, so that it creates the "look" of one large fixture.
Spud: A threaded waterway assembly inserted into the fixture for assembly of valves or trim. (Back spud - pipes are concealed behind wall. Top spud - pipes are exposed.)
Static Pressure: The pressure at the valve inlet that is exerted under a "no flow" condition.
Strainer: Device used to trap foreign materials, preventing blockage of the water passageway in urinals, or sinks.
Tank Cover: China lid which covers the toilet tank.
Tank Trim: Parts other than china regularly supplied with a toilet, for example, closet spuds wall hangers, and tank flush valves. Trim also includes flush valve, water control and trip lever.
Toilet Roughing-in measurement: Dimension from finished wall or floor to center of waste or supply opening or mounting holes. (99% of one and two piece toilets are 12" rough. Most flush valve toilets are 10" rough.)
Top mount: The whole faucet fits through the holes on the top of the sink with a plate covering the body of the faucet.
Trap: A fitting, device, or integral fixture portion so designed and constructed as to provide a liquid seal which will prevent the backpassage of sewer gas without materially affecting the flow of sewage or wastewater through it.
Trap Seal: Height of the water needed in a toilet bowl (measured from the opening of the toilet trap) to block sewer gasses from entering a bathroom.
Trip Lever: Located on either the left or right hand side of the toilet tank; used to actuate flush valve, or flush tower, to initiate the flushing cycle.
Two Piece Toilet: The toilet tank and bowl are molded separately with the need for attachment through the use of bolts.
Undermount Faucet: The body of the faucet mounts from under the sink and the trim goes on from the top.
Undermount Lavatory: The body of the sink attaches to the underside of the countertop. Depending on the design of the sink, faucets can be mounted on the countertop or the sink itself.
Urinal: A plumbing fixture, that receives only liquid body waste and, on demand, conveys the waste through a trap seal into a gravity drainage system.
Vacuum Breaker: A device to prevent water standing in a basin or container from being drawn back into your water supply if there is a complete loss of water supply pressure. A siphon can occur if the end of a hose, hand spray or spout is below the liquid’s surface, pulling contaminated water into the building’s water supply pipes.
Vitreous china: As applied to plumbing fixtures (<0.5% absorption), compound of ceramic materials fired at high temperature to form a nonporous body with exposed surfaces coated with ceramic glaze fused to the body.
Water closet: A plumbing fixture that stores a certain quantity of water inside a vitreous china or plastic tank until it is quickly released into another fixture. A toilet tank stores water until it is released and flushes into the toilet bowl.
Water control: Means of supplying and controlling water level in a tank.
Water surface: The surface of the still water in the toilet bowl when filled between flushes.
Wax ring: Located between the floor flange and toilet as a seal to prevent leakage and fumes. (Note: can also be provided with horn, which fits into the center of the waste pipe.)
Weir: Dam in the trapway that is specifically designed to give you recommended water seal and water spot.
Widespread: Measuring 8" from center of the left faucet handle to center of the right handle with everything in a separate hole (H-Spout-C).
