Considering whether or not you should turn off your sprinkler system during the winter months?
Winter creates a variety of challenges for homeowners looking to maintain a healthy lawn, especially in unpredictable weather regions like the greater Houston area. While winters are typically milder in Texas compared to northern climates, the question of whether to turn off your sprinkler system during the colder months is still an important consideration.
In this guide, we’ll explore the potential risks of leaving your sprinkler system active during the winter months and tips for proper winter sprinkler system maintenance. By the end, you’ll have a clear understanding of the best practices for winterizing your irrigation system and keeping your lawn in great shape.
Why Turn Your Sprinkler System Off During Winter?
While the greater Houston area most often experiences mild winters, there are certainly still days of the year when the weather gets cold enough to freeze and damage vulnerable equipment and materials.
This has especially been the case in recent years, where Houston has experienced record freezes (also known as cold snaps) with low enough temperatures to cause power loss from cold blasts passing through the region. Here are a few reasons why turning your sprinkler systems off during the winter, particularly in freezing conditions, is a good idea –
1. Reduced Watering Needs
Plants and warm-season grasses, which are the most common in Texas lawns, enter a dormant phase during winter (when temperatures drop and remain below 65 degrees), requiring significantly less water. Overwatering during this time can lead to soggy soil, which promotes fungal diseases and root rot. Turning off or reducing your irrigation schedule prevents these issues, saving water and the health of your lawn.
2. Potential Freeze Damage
Although freezing temperatures in Houston are sporadic, they do happen. Freezing temperatures can cause water in sprinkler pipes to expand, potentially leading to cracks, leaks, or even burst pipes. These damages can result in costly sprinkler replacement bills and severely disrupt your landscaping.
3. Water Conservation
During winter, natural rainfall is often sufficient for maintaining soil moisture levels. Running your sprinkler system unnecessarily wastes water, increases utility bills, and contributes to water scarcity concerns in the community.
When Should You Turn Off Your Sprinkler System in Texas?
Knowing when to adjust or shut down your sprinkler system is critical to avoiding damage and keeping your Texas lawn healthy. Here’s what you need to know:
Monitor the Weather:
In Houston, freezing temperatures most often occur between December and February. Keep an eye on weather forecasts to anticipate cold snaps. If freezing temperatures are predicted, it’s wise to turn off and drain your system temporarily to protect it from damage.
Consider Seasonal Rainfall:
When caring for your lawn during winter, you’ll want to consider how much rain it will receive over the course of the season. If consistent rainfall keeps your soil adequately moist, you can turn off your sprinkler system entirely. On the other hand, if it’s a dry winter, you might only need to run your sprinklers once every two to three weeks to maintain some levels of moisture.
How to Winterize Your Sprinkler System
Winterizing a sprinkler system doesn’t necessarily mean shutting it down completely. With the right steps, you can protect your irrigation system and ensure it’s ready to function when spring arrives:
1. Turn Off the Controller
If you decide to stop watering entirely, set your sprinkler system’s controller to the “off” or “rain mode” setting. This prevents the system from running automatically while preserving your programmed settings for future use.
2. Insulate Pipes and Backflow Preventers
Outdoor pipes and backflow preventers are especially vulnerable to freezing temperatures. Use insulation tape or covers designed for irrigation systems to shield them from the cold. This step is crucial even if you don’t completely turn off your system.
3. Drain Your Sprinkler System
If a deep freeze is expected, draining the water from your sprinkler lines can prevent damage. This involves shutting off the main water supply to the sprinkler system and using manual or automatic drain valves to empty the pipes.
4. Check Sprinkler Heads and Valves
Inspect your sprinkler heads and valves for any signs of wear or damage. Addressing these issues before winter ensures your system will perform optimally when it’s back in use.
5. Schedule Professional Sprinkler Maintenance
For peace of mind, consider hiring a professional lawn care and irrigation company to handle the winterization process to ensure it’s done correctly and your system is protected.

What Happens If You Don’t Winterize Your Sprinkler System?
Failing to prepare your sprinkler system for winter can result in a variety of issues, including:
- Burst Pipes: Frozen water expands, potentially causing pipes to crack or burst.
- System Malfunctions: Damaged valves or sprinkler heads may fail to work correctly when you resume watering in the spring.
- Increased Sprinkler Repair Costs: Fixing freeze-damaged sprinklers can be significantly more expensive than preventative maintenance.
- Water Waste: Unnoticed leaks from damaged pipes or valves can lead to excessive water usage and high utility bills.
Alternatives to Turning Off Your Sprinkler System
If you prefer to keep your sprinkler system active during the winter, there are ways to do so safely:
- Use a Rain Sensor: Install a rain sensor to automatically stop irrigation during rainy weather.
- Adjust Watering Schedule: Reduce the frequency and duration of your watering sessions to reflect your lawn’s lower water needs.
- Monitor Temperatures: Be prepared to turn off and drain the system temporarily if freezing weather is forecasted.
Winter Lawn Care & Sprinkler System Management
Although not required, turning off your sprinkler system during winter can save water, prevent freeze damage, and promote healthier soil conditions. However, the decision ultimately depends on Houston’s weather patterns and your lawn’s specific needs. Whether you choose to turn off your system entirely or simply adjust its settings, proper winterization is essential.
