drip irrigation clogging
I have two drip irrigation systems, using 2 AGRIFIM ISO-FLOW drip emitters (4/5 L/hr) per tree. I have a 20 psi pressure reducer and filter at the system source. Both irrigation lines worked fine until I expanded each line. Both have similar issues.
When I expanded from 800' to 1600' of 1/2' line and added about ISO-FLOW 20 drip emitters, the new spliced section does not work. The new drip emitters are slightly different than previous emitters. Instead of the black color Arifilm 5L/hr emitters, the irrigation supply store now carries Brown/black color Arifilm 4L/hr emitters. If I take the emitters off of the 1/4" tubbing, water flows freely from the tube. Any suggestions? Perhaps taking the pressure reducer off might help?
