1. Q: What is a water distribution system? ANSWER A network of pipes,
pumps, valves, and storage facilities that delivers potable water from treatment
plants to consumers.
2. Q: What is the primary purpose of a water distribution system?
ANSWER To deliver safe, adequate quantities of water at sufficient pressure to
meet customer demands.
3. Q: What are distribution mains? ANSWER Large pipes that carry water
throughout the distribution system to smaller service lines.
4. Q: What is a service line? ANSWER A pipe that connects the distribution
main to an individual customer's property.
5. Q: What is a gate valve? ANSWER A valve used to isolate sections of pipe
for maintenance or repair by completely stopping water flow.
6. Q: What is a fire hydrant? ANSWER A connection point on a water main
that provides water for firefighting purposes.
7. Q: What is an elevated storage tank? ANSWER A water storage facility
built above ground level to maintain system pressure and provide emergency
storage.
8. Q: What is a pressure reducing valve (PRV)? ANSWER A valve that
automatically reduces higher upstream pressure to a lower downstream
pressure.
9. Q: What is a check valve? ANSWER A valve that allows water to flow in
only one direction, preventing backflow.
10. Q: What is a meter? ANSWER A device that measures the volume of
water passing through it, typically used for billing purposes.
,11. Q: What is a fire hydrant auxiliary valve? ANSWER A valve located
between the main and fire hydrant used to isolate the hydrant for repairs.

main used to control water flow to a service line.
13. Q: What is a curb stop? ANSWER A valve located in the service line
near the property line used to shut off water to individual properties.
14. Q: What are distribution system appurtenances? ANSWER
Components such as valves, hydrants, meters, and fittings attached to
distribution pipes.
15. Q: What is a blowoff valve? ANSWER A valve used to drain water from
low points in the distribution system.

change the direction of flow.
20. Q: What is a reducer fitting? ANSWER A fitting used to connect pipes of
different diameters.
21. Q: What is a thrust block? ANSWER Concrete supports placed at bends
and tees to prevent pipe movement from water pressure.
22. Q: What is a valve box? ANSWER An enclosure that provides access to
underground valves from ground surface.
23. Q: What is a dead-end main? ANSWER A section of pipe that has flow
from only one direction with no outlet at the other end.
24. Q: What is a grid system? ANSWER A distribution system where mains
are interconnected in loops, allowing water to flow from multiple directions.
25. Q: What is a transmission main? ANSWER Large pipes that carry water
from the source or treatment plant to the distribution system.
26. Q: What is a storage reservoir? ANSWER A facility used to store treated
water for system demands and emergencies.
, 27. Q: What is a booster pump? ANSWER A pump used to increase water
pressure in the distribution system.
28. Q: What is a pressure zone? ANSWER An area of the distribution system
maintained at a specific pressure range.
29. Q: What is a butterfly valve? ANSWER A valve with a rotating disc used
for flow control and isolation.
30. Q: What is a ball valve? ANSWER A valve that uses a rotating sphere
with a hole through it to control flow.
31. Q: What is a plug valve? ANSWER A valve that uses a cylindrical or
tapered plug to control flow.
32. Q: What is a hydrant barrel? ANSWER The vertical pipe section of a
fire hydrant that connects the valve to the outlets.
33. Q: What is a hydrant nozzle? ANSWER The outlet on a fire hydrant
where hoses are connected.
34. Q: What is a Storz connection? ANSWER A quick-connect coupling
used on some fire hydrants and hoses.
35. Q: What is a water hammer arrestor? ANSWER A device used to
absorb pressure surges in piping systems.
36. Q: What is an altitude valve? ANSWER A valve that automatically
controls water level in elevated storage tanks.
37. Q: What is a float valve? ANSWER A valve controlled by a float
mechanism to maintain water levels in tanks.
38. Q: What is a pressure gauge? ANSWER An instrument that measures
water pressure in the system.
39. Q: What is a flow meter? ANSWER A device that measures the rate of
water flow through pipes.
