As fall arrives and leaves begin to drop, it’s the perfect opportunity to prepare your irrigation system for colder weather. Taking time now to protect your sprinkler heads and valves can prevent costly damage, conserve water, and ensure everything runs smoothly when spring returns. Use this fall irrigation checklist to tune up your sprinkler system, keep it in top shape, and avoid springtime surprises.
Season-End Tune-Up Checklist: Protecting Sprinkler Heads & Valves in Fall
Step 1: Inspect and Adjust Sprinkler Heads in Fall
Fall is an ideal time to closely inspect all sprinkler heads for clogs, cracks, or poor spray performance. Debris, dirt, and even lawnmower damage can block or damage nozzles, leading to dry spots or wasteful overspray. Here’s what to do:
- Clean each sprinkler head: Remove any accumulated debris, mud, or grass.
- Check for cracks or leaks: Look for visible damage or leaking when your system is running.
- Adjust spray patterns: Ensure water reaches all areas of your yard evenly, not sidewalks, driveways, or your home’s foundation.
Fine-tuning your system reduces water waste, saves money, and prevents foundation or pavement erosion.
Step 2: Make Changes to Your Watering Schedule
As days grow shorter and temperatures drop, lawns and gardens need less water. Adjust your sprinkler schedule to avoid overwatering, which can cause fungal diseases and waterlogged soil as grass growth slows down.
- Reduce frequency: Cut back on watering days and duration.
- Use rain sensors: Modern irrigation systems with rain sensors will automatically pause watering during wet weather, further conserving water.
Smart seasonal scheduling provides healthier plants and lower water bills.
Step 3: Properly Drain the Irrigation System to Prevent Freezing
Draining your irrigation system is critical before freezing temperatures set in. Water left in pipes, valves, or sprinkler heads can freeze, expand, and cause cracks or blowouts over the winter.
There are three effective methods for draining an irrigation system:
- Manual Drain: Open drain valves at the system’s lowest points to allow water to exit naturally.
- Automatic Drain: Some systems are designed to self-drain once water flow stops. Ensure these valves are working correctly.
- Blow-Out (Air Compressor) Method: For complete water removal, especially in large or complex systems, connect an air compressor to push out any remaining water. Take care to use correct air pressure and safety gear, or consult a professional.
Tip: Using an air compressor is considered the most thorough method, safeguarding all underground lines and components.
Step 4: Check Valves and Pressure Settings
Faulty valves can lead to leaks and wasted water or may compromise your system’s integrity over winter.
- Inspect all valves: Look for leaks, cracks, or worn seals, especially near pipe joints.
- Monitor system pressure: Too much pressure can damage sprinkler heads or fittings, while too little causes uneven watering. Adjust as needed.
- Test backflow preventer: This vital component ensures that dirty irrigation water doesn’t flow back into your clean water supply. Make sure it’s functioning, especially after cold snaps.
Step 5: Perform Seasonal Controller and Efficiency Adjustments
Fall is a great time to evaluate your overall irrigation needs:
- Adjust controller settings: Shorten watering times and reduce frequency as plants and grass need less.
- Upgrade controls if needed: Consider smart controllers connected to rain or soil moisture sensors for greater efficiency and convenience.
Smart upgrades can deliver long-term water savings and less hassle with seasonal adjustments.

Prevent Costly Problems Before They Start
Proactive fall maintenance protects your investment. Addressing these essential steps now helps you avoid cracked pipes, broken valves, and costly repairs that are all too common in spring if a system is neglected over winter. Don’t wait for cold weather to cause damage. Take action today for peace of mind.
Winterize Your Sprinkler System the Right Way
Not comfortable handling a full winterization yourself? Calling a professional is a smart investment. Experienced irrigation specialists can:
- Thoroughly drain and blow out your system
- Inspect for issues you may miss
