DOMAIN I — WATER METERS, COMPONENTS & PRINCIPLES
Question 1
What is the primary purpose of a water meter?
A. Increase water pressure
B. Filter drinking water
C. Measure the volume of water passing through a service
D. Regulate wastewater flow
Correct Answer: C
The primary function of a water meter is to measure and record the quantity of
water passing through the customer's service connection. The recorded
consumption is commonly used for billing, conservation, and system management.
Question 2
Which component of a traditional mechanical water meter converts water
movement into a measurable indication of flow?
A. Service saddle
B. Measuring element
C. Curb stop
D. Meter box
Correct Answer: B
,The measuring element responds to water flow and transfers that movement to
the meter's register. Depending on the meter design, the measuring element may
be a disc, turbine, piston, or another mechanism.
Question 3
What is the primary function of a water meter register?
A. Shut off the service
B. Increase flow velocity
C. Display or record measured water consumption
D. Remove sediment from the water
Correct Answer: C
The register displays or stores the meter's accumulated measurement. Depending
on the meter type, the register may be mechanical, electronic, or remotely
readable.
Question 4
A meter has a totalizer reading of 125,400 gallons at the beginning of a period and
127,850 gallons at the end. How much water was recorded during the period?
A. 1,450 gallons
B. 2,450 gallons
C. 2,850 gallons
D. 3,450 gallons
Correct Answer: B
Consumption is calculated by subtracting the beginning reading from the ending
reading: 127,850 − 125,400 = 2,450 gallons.
Question 5
What is the purpose of a meter coupling?
,A. Measure water temperature
B. Control water pressure
C. Connect the meter to the service piping
D. Detect electrical faults
Correct Answer: C
Meter couplings provide the mechanical connection between the meter and the
service piping and allow the meter to be installed or removed for maintenance.
Question 6
What is the purpose of a meter gasket?
A. Increase pipe diameter
B. Provide a watertight seal at a meter connection
C. Measure water consumption
D. Control the customer's water pressure
Correct Answer: B
A gasket seals the connection between mating surfaces and helps prevent leakage
at the meter connection.
Question 7
What is the primary purpose of a curb stop?
A. Measure consumption
B. Control water flow to a service connection
C. Filter water
D. Increase meter accuracy
Correct Answer: B
A curb stop is a valve used to shut off or restore water service to a property. It
provides a means of isolating the service from the water main.
, Question 8
Where is a typical water meter installed in relation to the customer's plumbing
system?
A. Downstream of every fixture
B. Inside the sewer main
C. At or near the point where water service enters the property or building
D. Inside the water treatment plant only
Correct Answer: C
The meter is normally located on the service connection so that water entering the
customer's system can be measured before it is distributed to individual fixtures.
Question 9
What is the purpose of a meter box?
A. Increase water pressure
B. Protect and provide access to the meter and associated components
C. Store treated water
D. Remove chlorine
Correct Answer: B
Meter boxes protect meters and valves from traffic, soil, and other environmental
conditions while allowing authorized personnel to access the equipment.
Question 10
Why should the meter register generally remain accessible?
A. To increase flow rate
B. To permit reading, inspection, testing, and maintenance
C. To reduce water temperature
D. To prevent all leaks
Correct Answer: B
