What is a common sign of a clogged emitter in a drip irrigation system?

A common sign of a clogged emitter in a drip irrigation system is the presence of dry spots in the irrigation area. When an emitter is blocked or partially obstructed, it cannot dispense water efficiently. This results in uneven distribution of water, leading to areas within the watering zone that receive insufficient moisture. Consequently, those areas may exhibit dry patches, indicating that the plants in those spots are not getting the necessary water for optimal growth.

Consistent water flow would typically indicate that the emitter is functioning properly rather than being clogged. Excessive water pooling can suggest overwatering or malfunctioning parts but does not directly point to an emitter blockage. Similarly, overly moist soil might indicate that the system is over-irrigating or that there is a leak rather than signaling an emitter issue. Therefore, recognizing dry spots as a symptom of a clogged emitter is essential for effective maintenance and ensures the irrigation system operates efficiently.
