Spring irrigation is already underway for many growers, but even when systems appear to be running smoothly, there are a few maintenance tasks that often get overlooked this time of year. These small checks can make a big difference in system performance, water efficiency, and preventing costly problems later in the season. Here are five commonly overlooked irrigation maintenance tasks to check this spring.

1. Checking for Worn or Damaged Nozzles

Nozzles experience constant wear during irrigation season. Even slight wear can change spray patterns and reduce distribution uniformity across your field.

Look for:

• Uneven watering patterns
• Visible wear or clogging
• Nozzles that aren’t spraying evenly

Replacing worn nozzles early can help maintain proper coverage and avoid wasted water.

2. Inspecting Filters

Filters often get attention early in the season but can quickly become clogged once irrigation begins.

Check for:

• Debris buildup
• Reduced water flow
• Pressure drops in the system

Cleaning filters regularly helps maintain consistent flow and protects the rest of your irrigation
equipment.

3. Checking Pressure Regulators

Pressure regulators help maintain consistent pressure across the system. If they’re not working correctly, parts of your system may receive too much or too little water.

Signs to watch for:

• Pressure fluctuations
• Uneven irrigation across zones
• Equipment operating outside normal pressure ranges

4. Flushing Drip Lines and Laterals

Sediment and debris can build up in drip lines and lateral tubing over time. Flushing the lines periodically helps prevent emitter clogging and maintain consistent water distribution.

5. Walking Your System

One of the most valuable maintenance steps is also the simplest: physically inspecting your system while it’s running.

Walk or drive your fields and look for:

• Leaks
• Dry spots
• Areas receiving too much water
• Equipment that isn’t operating normally

Catching small issues early can prevent larger problems later in the season.

A Few Small Checks Go a Long Way

Spring is a busy time, and once irrigation systems are running it’s easy to move on to other priorities. But taking time to check a few often-overlooked components can make a big difference in system performance and crop health.
