When you schedule a fall irrigation system tune-up, you’re protecting your system from winter damage by shutting down the controller, draining water from exposed sections, inspecting each zone for issues, and setting yourself up for a smooth start next season.
Why a Fall Tune-Up Matters Before Winter
In San Antonio, the occasional freeze or sudden temperature drop can still potentially damage irrigation system components if water is left sitting in pipes or above-ground valves. Turning off the controller, cutting the water supply, and draining exposed parts helps prevent bursting pipes, cracked valves, and water leaks.
By tuning up now you can avoid:
- Broken or misaligned sprinkler heads
- Leaks or sticking valves
- Backflow preventer damage
- Reduced efficiency and wasted water
1. Shut Down the Controller and Water Supply
Start by turning off the irrigation controller and shutting off the water supply to your system.
- Access your controller and switch the mode to “Off” or “Rain” so no automatic cycles run while you prep.
- Find the shut-off valve near the meter or backflow assembly and close it.
- Double-check that the system is inactive before moving to drainage.
2. Drain Exposed Components and Above-Ground Pipes
Even though San Antonio rarely sees deep ground freezes, exposed components like above-ground pipes or backflow preventers are still vulnerable. Here’s what to do:
- Locate all visible pipes, valve boxes, and backflow assemblies and drain any remaining water.
- If your system has manual or auto-drain valves, open them to let trapped water escape.
- For complex systems, compressed air can be used (with caution) to blow out lines zone by zone, only if your equipment supports it.
- Add insulation or foam covers to exposed pipes or backflow preventers left above ground.
3. Inspect and Repair Key System Components
With the system shut down and drained, you can walk through and check all essential components to save time next season. What to look for:
- Sprinkler heads: Check for damage, clogs, or misalignment. Clean or adjust as needed.
- Valves: Inspect for leaks or sticky operations that may cause zones to stay on when they shouldn’t.
- Coverage and pressure: You can test briefly before full shut-down or wait until early spring. Make sure spray patterns are accurate and water isn’t hitting sidewalks or driveways.
- Backflow preventer: Look for any signs of damage or leaks. Confirm that test-cocks are clear and the device is still functioning properly.
4. Adjust Controller Settings and Seasonal Programming
Even if you don’t fully drain the system, updating the controller now can prevent problems later.
- Set the controller mode to “Off” or “Rain/Standby.”
- If using a smart or seasonal-adjust controller, reduce run times or skip cycles during dormancy.
- Make a note of current settings so it’s easier to restore them in the spring.
5. Review Local San Antonio Considerations and Water Authority Guidance
Since you’re in San Antonio, it’s worth checking in with your local water authority.
- Visit the San Antonio Water System (SAWS) website for efficient irrigation tips, rebates, and local watering schedules.
- Keep in mind: while deep freezes are rare in central Texas, exposed valves and assemblies still need protection.
