Pressure compensated anti-syphon
A pressure compensating anti-siphon dripline not only delivers the right amount of water irrespective of the change in pressure or the terrain type but also prevents the suck-back when there is a negative pressure in the drip line. You can buy products manufactured by Rain Bird and NaanDanJain from here. PC inline XFS type Rain Bird drip hose variants with copper shield technology have flow rates such as 1.6 and 2.3 litres/ hour whereas the Amnon PCAS type flat blue dripper hose by NaanDanJain have flows rates of 1.1 and 1.6 litres/ hour.
