The Smart Valve has detected higher-than-expected pressure in the drip zone, which may indicate a clog or blockage. Drip irrigation operates within a specific pressure range. When water cannot exit the drip tubing properly, pressure builds up in the line.
The controller monitors system pressure during operation. If the pressure remains significantly above the expected drip operating range (around 40 PSI), the Smart Valve may determine that water is not flowing normally through the drip emitters. This usually indicates a clog or obstruction upstream of the drip tubing.
Recommended Remedies
Flush the end of the drip line using the flush valve to clear possible debris such as sand or small rocks.
Check the filter for debris and clean it if necessary (guide below).
Inspect the drip line for sections where emitters are not releasing water.
After clearing any blockages, run the zone again to ensure pressure returns to the normal drip operating range.
Turn off the irrigation system or main water supply feeding the filter. While each Irrigreen head has a built in valve to prevent this, it avoids any scenario of spraying water when you open the housing.
Most Netafim inline filters have a threaded cap or bowl.
Unscrew the housing by hand (or with a strap wrench if it’s tight).
Be careful not to cross thread the assembly, as it may require replacement.
Pull out the internal filter element. Depending on the model, it will be either:
A screen filter
A disc filter stack
Use a hose or running water to wash debris off the screen or discs.
For heavier buildup: Use a soft brush
Separate and rinse disc stacks if applicable.
Avoid using sharp tools that could damage the mesh.
Place the filter element back in the housing and screw the cap back on hand tight.
Open the Smart Valve in the app and check for leaks. The system should return to normal flow.
