How to Clean and Maintain Drippers & Filters: Best Practices for Longevity

Drip irrigation is one of the most efficient ways to grow more with less. However, like every system, it performs best when properly maintained. There are two key components in your drip system, namely drippers and filters, which require periodic cleaning and maintenance. If they’re clogged or non-functioning, your crop may suffer from uneven watering and resulting reduced yields and poor quality yields.

This guide is a hands-on resource for Indian farmers on how to keep drippers and drip irrigation filters clean, functional, and long-lasting with the help of Netafim India.

Why Cleaning Drippers and Filters is Essential

• Clogged drippers lead to under-irrigated zones, directly affecting crop health.
• Dirty filters allow debris, sand, and organic matter into the system, clogging drippers and reducing flow.
• Regular maintenance saves time, prevents system breakdown, and extends lifespan.

How to Maintain Drip System - Filters & Drippers (Routine & Deep Cleaning)

• Regular cleaning of primary filters like Hydrocyclone, Gravel/ Sand filters is essential- clean sediment tanks and perform backflushing every 7–10 days, depending on water quality.
• Maintain secondary filters (screen or disc filters) by opening and cleaning them weekly basis; prefer disc filters as they are more efficient and chemical-friendly.
• Take out the filter element, i.e Screen/ Discs and wash it in regular water. Perform the filter element cleaning once in 8 days as per the standard schedule. If water quality is poor, then clean it more frequently. Do not use a brush for cleaning.
• Make sure that the O-ring in the screen/ disc filter is in good condition.
• Avoid using Acid & other harmful materials for cleaning of filter elements.
• Flush mainlines, sub-mains, and laterals regularly- open the end caps or flush valves and let water run until clear; do this every 10–15 days or more frequently for open water sources or poor-quality water.
• Clean fertigation equipment like venturi and fertiliser tanks to avoid chemical or residue buildup- flush the system thoroughly after each fertigation cycle.
• Inspect filters, valves, and end caps periodically during irrigation to catch issues early.

Seasonal Maintenance Checklist (Before & After Cropping Cycle) 

• Flush the entire system before a new crop cycle
• Clean filters thoroughly and inspect for damage
• Check dripper flow and replace non-functional emitters
• Ensure all pipes, connectors, and valves are leak-free
• Perform Acid treatment after each season or according to water quality.
• Always use a proper dripline winder to roll and unroll the laterals—it prevents twisting, kinks, and physical damage.
• Store the unused parts and rolled dripline in a shaded, dry, rodent-free and insect-free area.
