To minimize the risk of drip irrigation or micro sprinkler clogging due to low water quality, it is important to flush your irrigation system from time to time. If your irrigation system needs to be flushed more frequently, use one of the best-kept secrets of drip irrigation system, the automatic flush valve. Automatic flush valves can play a significant role in conserving time and labor and can protect your drip irrigation system.
If the flush valve does not close (continues to flush), disassemble the flush valve. Inspect the spring and washer, cleaning or replacing as necessary, and reassemble.
If the line flushing valve does not seal (continues to flush), disassemble the flush valve. Inspect all components, cleaning or replacing as necessary, and reassemble. You should be able to blow and draw air through the drip emitter that is attached to the diaphragm, and the diaphragm should be free of any rips or tears.
Damage may occur if the flush valve has been subjected to higher than recommended pressure (greater than 50 PSI).
If manual flush valves or flush ports have been installed in lieu of line flushing valves, they should be opened and the system flushed at least three times in each irrigation season until the flowing water is visibly clean. The zone may need to be flushed more frequently depending on the quality of the water source.
Flushing of a drip system is highly recommended anytime that the system has been repaired.
