CIT System Maintenance and Troubleshooting

Question 1

What is a common sign of a clogged sprinkler nozzle?

Accepted Answer

Dry spots in the coverage area

Answer

A clogged sprinkler nozzle restricts or alters the water flow, leading to an uneven spray pattern or reduced water output in a specific area. This directly results in dry spots within the intended coverage zone, indicating that the plants in that area are not receiving adequate water and may suffer from drought stress.

Question 2

Which tool is best used to locate underground wire breaks?

Accepted Answer

Wire locator

Answer

A wire locator, also known as a wire tracker or fault finder, is specifically designed to detect the path and depth of underground wires and pinpoint breaks or faults. It works by sending a signal through the wire and detecting it with a receiver, making it an indispensable tool for troubleshooting electrical issues in irrigation systems.

Question 3

What is the likely cause of water leaking around a valve box?

Accepted Answer

Faulty or loose valve

Answer

Water leaking around a valve box is a strong indicator of an issue with the valve itself or its connections. This could be due to a faulty diaphragm, a loose connection at the valve manifold, a cracked valve body, or a worn seal, all of which allow water to escape and accumulate in the valve box.

Question 4

What should be done before troubleshooting an electrical zone failure?

Accepted Answer

Inspect controller settings and power

Answer

Before troubleshooting an electrical zone failure, it's crucial to first inspect the controller settings and ensure it has power. The issue might be as simple as incorrect programming, a tripped breaker, or a power outage, which are much easier to check than immediately delving into wiring or valve replacements. This systematic approach saves time and effort.

Question 5

What can cause low pressure in one irrigation zone?

Accepted Answer

Lateral line leak

Answer

A lateral line leak in one irrigation zone will cause a significant drop in water pressure specifically within that zone. The escaping water reduces the volume and pressure available to the sprinkler heads, leading to poor coverage and dry spots, while other zones might remain unaffected, indicating a localized issue.
