Certified Landscape Irrigation Auditor

What could be a consequence of using mismatched catch devices in an audit?

1. Increased water pressure

2. Reduced distribution uniformity

3. Improved efficiency

4. Faster water absorption

The correct answer is: Reduced distribution uniformity

Using mismatched catch devices during an audit can lead to reduced distribution uniformity. This is because different catch devices might have varying sizes, shapes, and flow characteristics, which can create inconsistency in how water is captured and measured across the irrigation system. If some devices collect significantly more or less water than others, it skews the data and gives an inaccurate picture of how efficiently the irrigation system distributes water. A lack of uniformity means that certain areas may be over-watered while others are under-watered, leading to inefficient water use, plant stress, and potentially increased water waste. Thus, correct matching of catch devices is essential for reliable audit results and optimal irrigation performance.
