The lowest point in a drainage system.
3. Describe the function of a yoke vent in relation to soil or waste stacks.
A yoke vent is used to drain excess water from fixtures.
A yoke vent prevents backflow of sewage into the fixtures.
A yoke vent connects a soil or waste stack to an adjacent vent
stack to maintain pressure balance.
A yoke vent serves as a support structure for the plumbing system.
4. Describe the components involved in a private sewage disposal system and
their functions.
, A private sewage disposal system is a type of plumbing fixture used
for waste disposal.
A private sewage disposal system consists of a septic tank that
collects waste and a subsurface disposal field or seepage pits that
allow for the effluent to be treated and absorbed into the ground.
A private sewage disposal system is a municipal system that treats
sewage for a community.
A private sewage disposal system includes only a septic tank that
stores waste without any treatment.
5. What is the definition of a private sewage disposal system?
a treatment facility that processes sewage for a city
a system that connects directly to a municipal sewer line
a septic tank with the effluent discharging into a subsurface
disposal field, into one or more seepage pits or into a combination
of subsurface disposal field and seepage pit
a holding tank that stores waste until it can be removed
6. Describe the process of creating a soldered joint in plumbing.
A soldered joint is made by twisting metal pipes together without
heat.
A soldered joint is created by melting a metallic mixture or alloy to
join metal parts together.
A soldered joint involves using adhesive to bond metal components.
A soldered joint is formed by welding metal parts at high
temperatures.
,7. A clevis hanger would be used to _____.
Support an individual pipe suspended from a ceiling
Provide seismic protection for piping runs
Secure a pipe to a wall
Support multiple pipes suspended from a ceiling
8. Describe how a flushometer tank operates within a plumbing system.
A flushometer tank functions independently to store water until
needed.
A flushometer tank operates by integrating with an air accumulator
vessel to release a specific amount of water for flushing fixtures.
A flushometer tank uses gravity to flush fixtures without any
mechanical components.
A flushometer tank is primarily used for heating water in plumbing
systems.
9. Receptacles and receivers attached to the plumbing system that collects or
retain for ultimate discharge into the plumbing treatment facility and point
of discharge?
Plumbing equipment
Plumbing fixture
Plumbing appliance
Plumbing appurtenance
10. Describe the role of a vent stack in maintaining the functionality of a
drainage system.
, The vent stack connects various fixtures directly to the main water
supply.
The vent stack is used to store excess water from the drainage
system.
The vent stack filters out impurities from the water before it enters
the drainage system.
The vent stack allows for the circulation of air, which prevents
vacuum formation and ensures proper drainage.
11. In a building designed for fire safety, how would the use of a dry standpipe
impact the fire department's response?
It would limit the amount of water available for firefighting.
It would require additional equipment to drain water from the pipe.
It would provide immediate access to water for firefighting without
the complications of water stagnation.
It would delay the response due to the need to fill the pipe with
water.
12. Describe the significance of the flood level rim in plumbing systems.
The flood level rim indicates the maximum water level to prevent
overflow and maintain safety.
The flood level rim is the point where drainage begins.
The flood level rim is a type of plumbing fixture.
The flood level rim is used to measure water pressure in pipes.
13. Is integrated within an air accumulator vessel which is design to discharge a
predetermine a quantity of water into fixture for flushing purposes.
