What is a common method of checking for leaks in an irrigation system?

Performing a pressure test is a widely recognized method for checking for leaks in an irrigation system. This procedure involves using a pressure gauge to measure the water pressure within the system. If there are any leaks, the pressure will drop over time, indicating where the leaks may be occurring.

Conducting a pressure test is advantageous because it provides a clear and direct assessment of the system's integrity. It allows for not only identifying the presence of leaks but also pinpointing their locations, which is crucial for efficient repairs. A well-maintained pressure level is essential for proper irrigation performance and to avoid water wastage.

In contrast, while monitoring water usage can give some insights into system performance, it does not specifically indicate leaks. Likewise, inspecting plants for overwatering can suggest that there might be issues with the system, but it does not directly identify a leak. Testing soil moisture content is valuable for understanding the water distribution in the soil but does not provide a straightforward method for detecting leaks in the irrigation infrastructure. Therefore, performing a pressure test remains the most effective and common method for leak detection in an irrigation system.
