Clogged drip irrigation system? here’s how to clean it

5. Add household bleach to the water-filled drip lines.

The bleach’s chlorine can reduce calcium carbonate buildup from hard water running through the lines.
>Introduce the bleach during the final 30 minutes of an irrigation cycle or however long it takes to fill all the drip lines with water.
>Enough bleach should be added so that by the time the irrigation cycle ends, the residual chlorine at the end of the system would be the same amount as found in any water treatment plant. (78 ml) of bleach mixed in (4000 l) of water.
>Use a metering pump to add a food-grade phosphoric acid (or vinegar) to the drip lines to keep their water’s pH at 7. Injecting acid for a short period of time, then rinsing it through the lines, should not harm the drip system. Do you want a drip system installed in your farm? fill in the form below:
