Which device prevents emitters from clogging?

• A. Pressure Regulator
• B. Check Valve
• C. Screen Mesh
• D. Filter

Answer: (D)

Solids in irrigation water are the main cause of emitter clogs, so the Remedy is to remove those particles before they reach the emitters. A filter is the device that does this by trapping debris with a filtering element (which can be a screen), keeping the emitters clear and maintaining consistent flow. A pressure regulator reduces pressure but doesn’t remove particles, so it won’t prevent clogging. A check valve stops backflow but doesn’t filter the water. A screen mesh by itself is an element used for filtration, but the complete filter assembly is what actually prevents clogs and should be maintained and cleaned regularly.
