Unclog A Drip Irrigation System

If you use a drip irrigation system to supply water to your vegetable garden and you have noticed that water isn't coming out of one of the system's drip emitters, dirt may be clogged inside of the tubing or drip emitter or the filter may need to be replaced. Inspect and clean the tubing and emitter and replace the filter if necessary by following the instructions below. As a result, your garden will receive plenty of water and crops growing in it will continue to thrive.


  • bucket of soapy water
  • handheld scrub brush (soft bristles)
  • cotton swab
  • water hose
  • screen mesh for filter

Remove The Malfunctioning Drip Emitter And Flush The Tubing

Turn off the irrigation system. Grasp the malfunctioning drip emitter and pull it firmly out of the tubing. Use a cotton swab that has been dipped into soapy water to dislodge any materials that are stuck inside of the emitter. Remove dirt from the rest of the emitter with a soft-bristled scrub brush and soapy water. Rinse the emitter off with a water hose afterwards.

Turn on the irrigation system for a few minutes to flush the tubing. Any debris that is trapped inside of the opening where the emitter was installed will be loosened during this step. Secure the drip emitter in its hole in the tubing.

Clean The Filter's Screen Mesh And Test The System

Turn off the irrigation system and locate the filter. The filter's cover may resemble a long cylinder and will be located near the shutoff valve. Remove the filter and inspect it for debris. Most irrigation systems use filters that have a piece of screen mesh in them. Remove any debris that is trapped in between holes in the mesh with a scrub brush and soapy water. Rinse the screen off with water once you have finished.

If the mesh has a lot of dirty buildup on it that you cannot remove, replace it with a new piece of mesh. Install the filter. When doing this, pay attention to the filter's cylinder-shaped cover. Make sure that the arrow on the outside of it is pointing towards the part that the filter is being connected to so that it is installed properly.

Turn on the drip irrigation system. If water is coming out of all of the drip emitters at the normal speed, you have successfully corrected the problem. Keep the system maintained by inspecting the emitters and filter occasionally and flushing the tubing with water when needed.
