This fall has been one of the warmest on record. But as the days are starting to get shorter and the nights cooler, we all know those freezing temperatures are soon to follow. It’s important to winterize your irrigation system to protect against unnecessary and costly damage to your system pipes, valves, and other components.
The backflow prevention device is one of the most important parts of your irrigation system as it serves the purpose of preventing accidental contamination of the main water supply by isolating the water in your system and stopping it from reentering that main water supply line. It is also the most costly component and most susceptible to freezing resulting in costly damage. When the thermometer starts flirting with 32 degrees, your chances of freezing and damage begin to increase significantly since this device is not buried and is exposed to the elements above ground.
Here are some helpful tips for an emergency shut off if the forecast is calling for freezing temps before you have had a chance to properly winterize your system:
- Turn your irrigation controller off so your system doesn’t run.
- Turn the water off to your irrigation system and drain your backflow unit.
- Cover the backflow device with a large towel or blanket followed by a large garbage bag. Then, use duct tape to secure the garbage bag around the device by taping the opening closed around the pipe.
If you haven’t properly prepared, act now. To winterize your irrigation system, it must be properly blown out with compressed air. This removes any remaining water in the lines and valves that could potentially freeze and cause pipes to crack or other parts to break. Once this important step is done, your irrigation system is set for winter.
We’ve seen it all – broken pipes, damaged landscapes and property due to irrigation systems that have not been blown. Don’t risk it. Give us a call today and let the professionals at Alpine Gardens safely winterize your system.
