Certified Landscape Irrigation Auditor

Why might an auditor refer to the manufacturer catalog?

1. To learn about installation techniques

2. To verify correct operating pressure

3. To find local distributors

4. To check competing brands

The correct answer is: To verify correct operating pressure

Referring to the manufacturer catalog is crucial for verifying correct operating pressure of irrigation equipment. The manufacturer usually specifies operating pressure ranges for their products to ensure optimal performance and efficiency. This information helps auditors determine if the irrigation system is operating within the recommended parameters, which is essential for water conservation and proper system functioning. When determining the appropriate operating pressure, understanding the specifications listed in the catalog allows the auditor to assess if pumps, valves, and emitters are functioning as intended. Operating outside the recommended pressure can lead to either inefficient water delivery or potential damage to the system components. While the catalog may provide guidance on installation techniques, local distributors, or competitor products, these aspects do not directly relate to the primary purpose of ensuring that the irrigation system operates effectively at the correct pressures. Therefore, the manufacturer's catalog serves as a vital resource for understanding the operational benchmarks and technical specifications required for efficient irrigation auditing.
