MAINTENANCE & REPAIR


Q A


Do you have any tricks to unplug emitters?


Should a system become noticeably plugged (>15% off the design flow), immediate


action needs to be implemented to recover the system. The use of shock treatments has not been satisfactory as it rips large particles loose, and they tumble down the line and plug the ends.


A system of “push and cook” seems to provide more consistent, positive results. In this system, a grower applies the appropriate remedial chemical 100% of the time, then cycles through the zones in one- or two-hour intervals. This allows each emitter to have a gentle injection of product and time to activate before the pulse comes again. This push and cook system has been found to be quite effective at system recovery.


Maintaining all areas of the drip system is essential to produce uniform crops, such as in this drip-irrigated onion field.
