The following was sourced from Mr. Rooter.

ABS : Aristocraft bristone styrine, a rigid black plastic pipe used for drain, waste, and vent lines.

Aerator : A device screwed into the end of a faucet spout that mixes air into flowing water, and controls flow to reduce splashing. It sometimes contains a baffle to reduce flow to 2.5 gpm.

Air Lock : Blockage in the flow of liquid, esp. on the suction side of a pump caused by an air bubble in the line.

Angle Stop : A shutoff valve between the water pipes and a faucet. Its inlet connects to the water supply pipe in a wall, and its outlet angles up 90 degrees toward the faucet. These are usually used to shut off water to a fixture in case of an emergency repair rather than daily usage.

Anode Rod : A sacrificial rod installed in a water heater that protects the tank from corrosion, helping to extend the life of the tank.

Anti-Siphon : Preventive device for the backflow of liquid into a system. Used on sprinkler systems to prevent water from trickling back into the supply that is feeding it.

BTU : British Thermal Unit - A unit of heat energy required to raise the temperature of 1 lb. of water 1 degree Fahrenheit.

Back Flow Preventer : A device to prevent water from traveling from one system back into any part of the main distribution system, usually by siphoning, esp. into a potable water supply. This is generally required for sprinkler systems, handheld showers, pullout faucet spouts, kitchen sprayers, etc.

Back Pressure : Pressure that resists the flow of fluid in a piping system.

Backwater Valve : Sewer line valve that prevents sewage from flowing back into the house.

Ball Check Valve : A valve that uses a ball to seal against a seat to stop flow in one direction.

Ballcock : The fill valve that controls the flow of water from the water supply line into a gravity-operated toilet tank. It is controlled by a float mechanism that floats in the tank water. When the toilet is flushed, the float drops and opens the ballcock, releasing water into the tank and/or bowl. As the water in the tank is restored, the float rises and shuts off the ballcock when the tank is full.

Basin Wrench : A wrench with a long handle with jaws mounted on a swivel that allows the jaws to reach and handle nuts to fasten faucets to a previously installed sink.
Blowbag : A drain-cleaning device consisting of a rubber bladder with a hose fitting on one end and a nozzle on the other. The device attaches to a water hose and is inserted into a clogged drainpipe. As water is introduced, it expands to grip the pipe, and releases pulsating bursts of water through the nozzle, forcing water through the pipe to clear the obstruction.
