<p>Drip irrigation delivers water close to the root zone, but blocked filters, sediment, algae, mineral deposits, and damaged laterals can make application uneven. Routine <strong>drip-system maintenance</strong> helps protect water, energy, fertilizer, and crop performance.</p>
<h2>Before and during irrigation</h2>
<ul>
<li>Inspect the pump, mainline, sub-mains, and joints for leaks.</li>
<li>Check for unusual pressure changes.</li>
<li>Compare emitter flow near the beginning and end of representative laterals.</li>
<li>Straighten kinked pipes and repair cuts with suitable fittings.</li>
<li>Look for dry or overwatered patches while the system is running.</li>
</ul>
<h2>Maintain the filter</h2>
<p>The correct screen, disc, or media filter depends on the water source and system design. Rising pressure difference across a filter or declining flow can indicate blockage. Clean and service the filter according to the manufacturer's instructions, and never operate the system without the required filtration.</p>
<h2>Flush the lines</h2>
<p>Open the ends of mains, sub-mains, and laterals in the recommended sequence and run water until it becomes clear. The required frequency depends on water quality and operating conditions. Close every end securely after flushing and check the field again for leaks.</p>
<h2>Be careful with chemical treatment</h2>
<p>Acid or other treatments may be used for mineral or biological clogging, but the wrong product or concentration can injure crops, damage equipment, and harm the operator. Test the water and obtain guidance from the system manufacturer or a trained professional. Follow label directions and use appropriate protective equipment.</p>
<p><strong>Takeaway:</strong> Keep a maintenance log with pressure, cleaning, flushing, repair, and water-quality records. Small changes found early are easier to correct than widespread emitter failure.</p>
