The flush valves are used conventionally for flushing the lines of a drip system automatically at the beginning of each irrigation cycle. They have been installed at the very end of each drip lateral or drip line and they release approximate one gallons of water, every time the zone is powered on. The maintenance of your irrigation systems can be reduced with increased dripline performance. For periodic flushing of the irrigation system at the start and end of every irrigation cycle, they are used. A very small amount of water is passed through at the start and end of every cycle. During the installation of an automatic flush, the valve is needed to be ensured that it is covered with an 8” irrigation box. It is advised to observe the flushing operation after the completion of the installation for making sure that each valve is flushing properly and then for repeating this observation at the start of each irrigation season. The pressure needs to checked and compared to the lateral maintenance inspection.
