Line Flushing Valves are used to provide a cleansing action in the dripperline each time the zone is turned on.

When a zone is turned on, the flush valve begins dumping water into a sump (valve box).

The dumping of water (additional flow) allows the velocity of water inside the dripperline to increase momentarily helping to clean the inside walls of the tubing and drip inlet filters.

This action moves sediment out of the zone and into the sump.

Install the Flush Valve at the lowest point or furthest point from the water source.
