What a figure-8 end closure is
A figure-8 end closure is shaped like the number 8. The end of the lateral is folded back and passed through one loop; the fold stops the water. It is the simplest way to close the end of a drip line and needs no tools or glue.
Its main advantage is that it opens in one movement. At the end of the season, or every so often, opening the line ends lets the water carry out the sediment and particles that have collected; this flushing helps stop drippers from clogging.
Size and ordering
The end closure in our rows is for 16 and 20 mm pipe and fits lateral tubing and dripline of the same size. If you need a fixed plug, you can also choose the end plug from the 16 and 20 mm fittings.
In your enquiry give the diameter and quantity. The number of end closures equals the number of lateral rows.
Flushing lines by opening the lateral ends
To flush, at normal working pressure, open the end closures of a few rows at a time and let the water run until it comes out clear. Then close them again and move on to the next rows. Opening all rows at once drops the pressure so far that flushing does little good.
How often to flush depends on water quality; muddy water or water with algae needs more regular flushing. A short flush after each fertiliser feed also helps stop fertiliser settling in the drippers. Because the figure-8 closure opens and closes without tools, it makes this quick and simple.
