What is a potential indicator of low voltage in an irrigation system?

A potential indicator of low voltage in an irrigation system can be that valves don't operate properly. When there is insufficient voltage supplied to the irrigation system, it can directly affect the performance of the valves. These valves typically require a specific voltage to open and close correctly. If the voltage is low, the electro-mechanical components inside the valves may not function as intended, leading to erratic performance such as valves failing to open, closing intermittently, or not responding at all.

This situation can stem from issues such as a faulty transformer, long wire runs that cause voltage drop, or poor connections. Recognizing that valve operation is compromised due to voltage problems is crucial for diagnosing and repairing an irrigation system effectively.
