What should be ensured during an irrigation system audit tune-up?

• A. Install New Controllers
• B. Ensure Drip Valve Filter
• C. Remove All Components
• D. Change the Water Source

Answer: (B)

During an irrigation system audit tune-up, it is essential to ensure that the drip valve filter is functioning properly. The drip valve filter plays a critical role in preventing sediment, debris, and other contaminants from clogging the drip emitters and affecting the overall efficiency of the irrigation system. If the filter is dirty or damaged, it can lead to reduced water flow, uneven watering, and ultimately result in stressed plants or wasted water.

By focusing on the condition and functionality of the drip valve filter during an audit, landscapers can ensure that the irrigation system operates at its best efficiency, promoting healthy plant growth while conserving water. This makes it a vital step in maintaining a water-efficient landscape, aligning well with the principles of QWEL practices.

In contrast, installing new controllers, removing all components, or changing the water source may not directly address the immediate performance of the existing irrigation system. These actions could be unnecessary or overly complicated at the stage of a basic audit tune-up that aims to optimize current system functionality rather than overhaul it entirely.
