how to turn on irrigation system after winter

Spring has sprung, and it's time to get your lawn and garden looking their best. After a long winter, your irrigation system needs a little TLC before it can work its magic. Turning it on too soon can lead to costly repairs, so follow these steps to ensure a smooth start to your watering season.

Inspecting Your Irrigation System: A Pre-Start Checklist

Before you even think about flipping the switch, a thorough inspection is crucial. This prevents costly repairs down the line and ensures your system runs smoothly all season long.

1. Check for Winter Damage:

Pipes and Backflow Preventer: Look for any cracks, leaks, or damage to your pipes, especially near valves and fittings. Pay close attention to your backflow preventer; winter freeze can cause significant damage here.
Sprinkler Heads: Examine each sprinkler head for damage, cracks, or debris. Ensure they're free to rotate and pop up properly. Winter can leave them buried under debris or slightly damaged.
Controller: Inspect your irrigation controller for any signs of damage or malfunction. Make sure the display is working correctly.
Wiring: Look for any exposed or damaged wiring. Repair or replace any damaged sections. Damaged wiring is an easy fix when caught early, but becomes an expensive problem later.

2. Clear Debris:

Sprinkler Heads: Use a small tool to clear out any debris lodged in the sprinkler heads. A stiff wire brush or even a screwdriver can work wonders. This is essential for even water distribution.
Pipes and Valves: Ensure there are no obstructions in your pipes or valves. A quick flush can help remove any sediment buildup. A clogged valve can lead to uneven watering or sections that don't water at all.

3. Test the System (Slowly):

Start with Low Pressure: Turn your water supply to the irrigation system slowly. Don't rush this. This prevents damage from sudden water pressure changes. A sudden surge can cause leaks or damage to your system's components.
Check Each Zone: Once the water is on, activate each zone individually. This allows you to pinpoint any issues within specific areas of your landscape. Watch for low pressure, leaks, or sprinkler heads that aren't functioning correctly.
Inspect for Leaks: Carefully walk around your yard to look for any leaks or areas where water isn't reaching correctly. Address these problems before moving on. Fixing leaks early saves you water and money.

How to Turn on Your Irrigation System: A Step-by-Step Guide

Once your inspection is complete, it’s time to get your system running.

Turn on the Main Water Supply: Locate your main water valve for the irrigation system. Slowly open the valve to avoid a sudden pressure surge.
Power Up the Controller: Make sure your irrigation controller is plugged in and turned on. You should see the display illuminate.
Check the Timer: Set your irrigation timer for the desired watering schedule. Begin with shorter watering times and gradually increase them as needed.
Run Each Zone: Manually run each zone to check for proper operation. If you notice any problems, address them immediately.
Monitor Performance: Pay attention to your system's performance for the first few days. Watch for issues like low water pressure or damaged sprinkler heads.

Troubleshooting Common Irrigation System Problems

Even with careful preparation, problems can occur. Here are some common issues and how to fix them:

Q: My sprinkler head isn't popping up.

A: Check for debris clogging the head. Try gently clearing the head with a small tool. If the problem persists, replace the sprinkler head.

Q: I have low water pressure in one zone.

A: Inspect the pipes and valves in that zone for blockages. A partially clogged valve can reduce water pressure to that area.

Q: I've noticed a leak.

A: Quickly locate and repair the leak. Depending on the severity and your DIY abilities, you may need to call a professional. Small leaks can escalate into larger problems if not addressed quickly.

Maintaining Your Irrigation System Throughout the Season

Regular maintenance throughout the growing season will prevent many problems and keep your system running efficiently. Consider these tips:

Inspect Regularly: Check your system regularly for leaks, clogs, or damaged components.
Adjust Watering Schedules: As weather conditions change, adjust your watering schedule accordingly.
Clean Sprinkler Heads: Regularly clean sprinkler heads to remove debris and ensure even water distribution.
Winterize Your System (When the time comes): Properly winterize your system to prevent damage from freezing temperatures.

By following these steps, you can ensure your irrigation system is ready for spring and provides efficient, reliable watering for a healthy lawn and thriving garden. Remember, preventative maintenance is key to a long-lasting and trouble-free irrigation system.
