Flush Caps
■ Automatic flush caps operate by automatically flushing a small
amount of water each time the system is activated. Observe the
flush operation annually to ensure that flushing is occurring
properly.
■ The system must be flushed thoroughly after repairs or alterations
are made to the irrigation components. Automatic flush caps do
not allow enough water to pass through excessive debris and,
therefore, must be removed in order to effect a manual flush.
■ Manual flush caps should be flushed three times each irrigation
season for a period of 30 to 60 seconds or until the flush water is
visibly clean. More frequent flushing may be required under
extremely dirty water conditions. Flushing is also necessary any
time the system is repaired.
