its been more than 4 years that i am using drip irrigation in my farm at times there is no proper in flow of water because some amount of residue or manure must have got struck in the drip line apart from running fresh water in pressure is there a chemical which i can use to clear the drip pipe.
Use Urea phosphate or Phosphoric Acid to clean the drip pipes.
Dip into sulphuric acid and clean it if its non isi mark
First use pressure to clear out the pipes and then use an inline disc filter which is available on amazon to make sure you dont get future blockages.
