A watertight receptacle which the discharge of sanitary plumbing system or part thereof, designed and constructed to retain solids, digest organic matter through a period of detention and to allow the liquids to discharge into the soil outside the tank through a system of open jointed subsurface pipings or a seepage pit
Correct Answer
A. Septic tank
Explanation
A septic tank is a watertight receptacle that is designed to retain solids and digest organic matter from a sanitary plumbing system. It allows the liquids to discharge into the soil outside the tank through a system of open jointed subsurface pipings or a seepage pit. This system helps to treat and dispose of wastewater in a safe and environmentally friendly manner.
2.
Any waster water containing animal or vegetable matter in suspension or solution and may include liquids containing chemicals in solution
Correct Answer
B. Sewage
Explanation
Sewage refers to any wastewater that contains animal or vegetable matter in suspension or solution, which may also include liquids containing chemicals in solution. It is the term used to describe the water and waste materials that are carried away from homes, buildings, and industries through a sewer system. Sewage is typically treated in a septic tank or through a centralized sewage treatment plant to remove contaminants before being discharged into the environment.
3.
A pipe or conduit for carrying sewage and wastewater
Correct Answer
C. Sewer
Explanation
A sewer is a pipe or conduit that is used to carry sewage and wastewater away from buildings and homes. It is an essential part of a city's infrastructure, as it helps to prevent the accumulation of waste and keeps the environment clean and healthy. Sewers are typically connected to septic tanks, which collect and treat the sewage before it is discharged into the sewer system. Sewage refers to the waste material that is carried in the sewer, while siphonage refers to the process of using a siphon to move liquid from one place to another.
4.
A suction created by the flow of liquids in pipes; a pressure less than the atmospheric pressure
Correct Answer
D. SipHonage
Explanation
Siphonage refers to a suction created by the flow of liquids in pipes, specifically a pressure less than atmospheric pressure. In the context of the given options, septic tank, sewage, and sewer do not directly relate to the concept of siphonage. Therefore, siphonage is the correct answer.
5.
A pipe which carries the discharge toilets or similar fixtures, with or without the discharge of other fixtures, to a sewer or approved drain
Correct Answer
A. Soil pipe
Explanation
A soil pipe is a type of pipe that is specifically designed to carry the discharge from toilets or similar fixtures, either on its own or along with the discharge from other fixtures, to a sewer or approved drain. It is different from other types of pipes as it is specifically used for this purpose and is not meant for carrying any other type of waste or water.
6.
Any pipe which conveys the discharge of water closet, urinal or fixtures having similar function, with or without the discharges from other fixtures to the building drain or building sewer
Correct Answer
B. Soil stack
Explanation
A soil stack is a type of pipe that is used to convey the discharge of a water closet, urinal, or other fixtures with similar functions, along with any other discharges from fixtures, to the building drain or sewer. It is typically a vertical pipe that extends through multiple floors of a building. The term "soil" refers to the waste material that is being conveyed through the pipe.
7.
The end of a pipe which fits into a bell; also a word synonymously with faucet
Correct Answer
C. Spigot
Explanation
A spigot is a device that fits into a bell-shaped opening, similar to the end of a pipe. It is also commonly used as a synonym for a faucet. Therefore, spigot is the correct answer as it accurately describes the end of a pipe that fits into a bell and can also be referred to as a faucet.
8.
A general term used for any vertical line of soil, waste or vent piping
Correct Answer
D. Stack
Explanation
A stack is a general term used for any vertical line of soil, waste, or vent piping. It can refer to a soil stack, which specifically carries soil or waste materials, or a vent stack, which carries air and gases out of the plumbing system. The term "stack" is used to describe the vertical nature of the piping, regardless of its specific purpose.
9.
A tank or pit below the normal grade of gravity receiving liquid wastes or sewage from which the wastes or sewage must be mechanically pumped to a higher receiving point
Correct Answer
A. Sump
Explanation
A sump is a tank or pit that is located below the normal grade of gravity and is used to receive liquid waste or sewage. In order to move the waste or sewage to a higher point, mechanical pumping is required.
10.
A fitting or device designed and constructed to provide, when properly vented, a liquid seal which prevents backflow and passage of foul air and gases without materially affecting the flow of sewage or wastewater through it
Correct Answer
B. Trap
Explanation
A trap is a fitting or device that is designed to create a liquid seal, preventing the backflow and passage of foul air and gases. It is important for maintaining proper plumbing and sewage systems as it allows for the flow of sewage or wastewater while preventing the escape of unpleasant odors and harmful gases.
11.
A pipe or opening used for ensuring the circulation of air in a plumbing system and for relieving the negative pressure exerted on trap seals
Correct Answer
C. Vent pipe
Explanation
A vent pipe is a pipe or opening in a plumbing system that is used to ensure the circulation of air and relieve negative pressure on trap seals. It allows air to enter the system, preventing suction or siphoning of water from traps, which could lead to unpleasant odors or loss of water seal. The vent pipe helps maintain proper drainage and prevents the buildup of harmful gases in the plumbing system.
12.
The vertical pipe installed primarily for providing circulation of air to and from any part of the soil, waste of the drainage system
Correct Answer
D. Vent stack/main vent
Explanation
A vent stack/main vent is a vertical pipe that is installed in a drainage system to provide circulation of air to and from any part of the soil, waste, or drainage system. This helps to prevent the buildup of pressure and allows for proper drainage by allowing air to escape. It also helps to prevent the escape of foul odors and gases from the system.
13.
A pipe which conveys only wastewater or liquid waste free of fecal matter
Correct Answer
A. Waste pipe
Explanation
A waste pipe is a type of pipe that is specifically designed to carry only wastewater or liquid waste that does not contain any fecal matter. It is used to transport and dispose of waste materials from sinks, showers, and other plumbing fixtures. Unlike water distributing pipes, water mains, or water service pipes, which are used to distribute and supply clean water, a waste pipe is dedicated solely to the removal of waste.
14.
The water supply which conveys potable water from the building supply pipe to the plumbing fixtures and other outlets
Correct Answer
B. Water distributing pipe
Explanation
The term "water distributing pipe" refers to a pipe that carries potable water from the main water supply to various plumbing fixtures and outlets within a building. This pipe is responsible for distributing the water to different areas and ensuring a steady flow of water to the desired locations. It is an essential component of the plumbing system as it allows for the efficient and effective distribution of clean water throughout the building.
15.
The water supply pipe provided by the water utility company where local individual fixtures and other outlets
Correct Answer
C. Water main
Explanation
The term "water main" refers to the main pipe that carries water from the water utility company to individual fixtures and outlets. It is the primary pipe in the water supply system that distributes water to different areas. The other options, such as waste pipe, water distributing pipe, and water service pipe, do not accurately describe the main pipe that supplies water to the entire system.
16.
The first after the water main before the water meter
Correct Answer
D. Water service pipe
Explanation
The correct answer is "water service pipe." In a water distribution system, the water service pipe is the pipe that connects the water main to the water meter. It is responsible for delivering water from the main line to individual properties. The waste pipe carries wastewater away from the property, while the water distributing pipe is used to distribute water within the property.
