BACKFLOW EXAM 2026 FULL PRACTICE
QUESTIONS AND ANSWERS
◉ RP assembly minimum side clearance. Answer: 12 inches
◉ RP assembly minimum site clearance were test. Cops are located..
Answer: 24 inches
◉ RP assemblies, protect against which types of health hazards.
Answer: Both non-health hazard and health hazard
◉ RP assemblies are good for. Answer: Back pressure and back
siphonage
◉ RP assemblies, protect backflow of toxic materials, true or false.
Answer: True
◉ The relief valve on an RP assembly shall be located. Answer:
Below the first check valve
◉ True or false the design standard for the number one check valve
loading for an RP shall be at least five psi. Answer: True
,◉ The differential pressure relief valve of an approved, reduce
pressure principle backflow prevention assembly must discharge
water from the zone whenever the zone pressure is. Answer: Two
psi or less below the supply pressure
◉ As per the manufacturer, the buffer between the actual first check
valve pressure drop, and the differential pressure relief valve
opening point should be at least. Answer: 3.0 psi
◉ During the field test of a reduced pressure principle backflow
prevention assembly, the differential gauge reading cannot be
lowered enough to get the relief valve to open, even after opening
the gauge needle valve 1/4 turn this implies that. Answer: Water is
leaking past the number two shut off valve with demand
◉ There is continuous discharge from the relief valve of a reduced
pressure type backflow prevention assembly during a non-flow
condition. The static pressure drop across the number one check
valve is 2.3 psi. The malfunction is most likely.. Answer: Number one
check valve fouled
◉ The relief valve of a reduced pressure principle backflow
prevention assembly is observed, discharging small spits of water
intermittently. This condition is most likely caused by.. Answer: The
upstream pressure is fluctuating
, ◉ In testing, a reduced pressure principle backflow prevention
assembly the first test to be performed and recorded shall be the.
Answer: Differential pressure relief valve
◉ There is a continuous discharge from the relief valve of a reduced
pressure principle backflow prevention assembly. The pressure drop
across the number one check valve is 9.0 the malfunction is most
likely.. Answer: Debris fouling the relief valve seat
◉ A new reduced pressure principle backflow prevention assembly
has been installed and the initial test shows a relief valve opening
pressure of 2.6 psi and the first check valve drop of 4.6 psi what is
the most likely the cause of this condition. Answer: A slightly fouled
first check valve
◉ Which of the following is used to properly field test and reduced
pressure principle backflow prevention assembly. Answer:
Differential pressure gauge
◉ If water is continuously flowing from the relief valve port of a
reduced pressure principle backflow prevention assembly, it could
be reported that. Answer: The first check may be fouled
◉ What date did the cross connection control policy handbook get
adopted?. Answer: December 19, 2023
