As the crisper feeling of fall begins to settle in and winter approaches, it is time to think about preparing your home for the cold months ahead. In California fire sprinkler systems are mandatory for new home construction for single-family homes, townhomes, and duplexes built on or after January 1, 2011. One critical task for homeowners with a lawn irrigation system is winterizing your sprinkler system. Proper winterization ensures that your sprinklers will be ready to work again when spring arrives and protects your system from damage caused by freezing temperatures. Below is a step-by-step process to help you through the activity.
Step-by-Step Guide
1. Turn Off the Water Supply
The initial step in winterizing your sprinkler system is to shut off the water supply. Find the main valve that controls water flow to the system and close it. This blocks any additional water from entering the pipes during the winterization process.
2. Drain the System
There are three common methods to drain the remaining water from your sprinkler system: the manual drain method, the automatic drain method, and the blow-out method. The method you choose will differ based on the type of system you have.
- Manual Drain Method: If your system is equipped with manual drain valves, you will need to open each valve to allow the water to drain out. Start with the valve farthest from the main shut-off valve and work your way closer.
- Automatic Drain Method: Systems with automatic drain valves will automatically release water when the pressure in the pipes drops below a certain level. To activate this, simply shut off the water supply and then open the system’s controller to allow the water to drain.
- Blow-Out Method: The blow-out method is the most effective way to remove water from your sprinkler system. This involves using an air compressor to force air through the pipes, blowing out any remaining water. Caution: The blow-out method can be dangerous if not done correctly, so consider hiring a professional if you are unsure.
3. Shut Down the Controller
Once the water has been drained, turn off the sprinkler system’s controller. Some controllers have a “rain” or “off” mode, which allows the controller to remain powered without activating the sprinklers. If your controller does not have this mode, simply unplug it, or shut off the power.
4. Insulate Above-Ground Components
Any above-ground components, such as the backflow preventer and exposed pipes, should be insulated to protect them from freezing. Use insulation tape, foam pipe covers, or specialized insulation bags to cover these parts. Make sure the insulation is secure and will stay in place throughout the winter.
5. Inspect and Maintain Your System
Winterizing is a good opportunity to inspect your sprinkler system for any signs of wear or damage. Check for cracks, leaks, or broken sprinkler heads and make necessary repairs or replacements. This step will save you time and added costs when spring arrives, and your system will be ready to go.
Winterizing your sprinkler system is a relatively simple task that can save you from expensive repairs and ensure that your lawn stays lush and green when spring returns. Whether you decide to do it yourself or hire a professional, taking the time to properly winterize your system is a smart idea for any homeowner.
By following these steps, you can be certain your sprinkler system is protected from the harsh winter weather, and you will be ready to enjoy a beautiful lawn come springtime.
