These 10 free CIT questions are organized by exam domain, so you can see how each part of the Certified Irrigation Technician (CIT) blueprint is tested. Reveal the answer and explanation under each question.
An irrigation system is protected by a pressure vacuum breaker (PVB). A booster pump is later installed downstream of the PVB to serve an elevated zone. What action is required?
Correct answer: D - Replace the PVB with a reduced pressure zone assembly (RP)
A turf zone on a clay slope is programmed for 15 minutes. Water begins running off the slope after about 5 minutes, and the root zone remains dry. What is the BEST correction?
Correct answer: A - Split the run time into three 5-minute cycles with soak periods
A saturated area is present in the lawn at all times, including overnight when no zone is scheduled or running. What does this MOST likely indicate?
Correct answer: C - A leak on the mainline, which stays pressurized between cycles
A technician calls 811 and the utility locate is completed and marked. While trenching for a new lateral, the crew strikes an unmarked line carrying power to landscape lighting. Why was this line NOT marked?
Correct answer: D - The 811 service marks utility-owned lines, not privately owned lines
A homeowner reports that their system waters all night. The controller has one program with eight stations, each set to 15 minutes, and three start times are programmed. What is the MOST likely explanation?
Correct answer: A - Each start time runs the entire program, so all eight stations run three times
With the station commanded on, a technician measures 24 VAC at the solenoid leads. The solenoid is disconnected and measures 34 ohms, within the manufacturer's published range. The valve still does not open. What is the MOST likely cause?
Correct answer: C - Debris obstructing the valve's bleed port or a failed diaphragm
No station on a conventionally wired controller will activate. The display is normal, the program is correct, and the controller outputs 24 VAC at each station terminal when commanded. What should the technician suspect FIRST?
Correct answer: C - A break in the common wire shared by all the valves
A technician measures 24 volts across a solenoid drawing 0.4 amps. What is the resistance of the solenoid?
Correct answer: C - 60 ohms
What holds a standard electric diaphragm control valve in the CLOSED position?
Correct answer: B - Line pressure in the chamber above the diaphragm, plus the spring
Static pressure at the point of connection reads 75 psi. With the zone running, pressure at the farthest sprinkler reads 32 psi. What does this MOST likely indicate?
Correct answer: B - Excessive friction loss from undersized pipe or excess zone flow
