Why Should I Winterize My Irrigation System?
If you have an irrigation system for your lawn or garden, you might be wondering if you need to winterize it before the cold season arrives. The answer is yes, winterizing your irrigation system is a crucial step to protect it from freeze damage, avoid emergency leaks, and/or costly repairs in the spring. In this blog, we will explain what winterization is, how it works, and what methods you can use to winterize your irrigation system.
What is Winterization?
Winterization is the process of removing water from your irrigation system before the temperature drops below freezing. Water expands when it freezes, which can cause pipes, valves, sprinklers, and other components to crack or burst. This can result in leaks, flooding, and reduced water pressure in your system. To prevent this from happening, you need to drain the water from your system and shut it down until the next watering season.
How Does Winterization Work?
There are three basic methods for winterizing your irrigation system: manual drain, automatic drain, and blow-out. The method you use depends on the type of irrigation system you have and the climate you live in. Here is a brief overview of each method:
Manual drain: This method involves opening valves at the ends and low points of the piping and letting the water drain out by gravity. You also need to drain the backflow device and any sprinklers with check valves. This method is simple, but it may not remove all the water from the system providing the opportunity for freeze damage.
Automatic drain: This method relies on valves that automatically open and release water when the pressure in the system falls below a certain level. You activate this function by turning off the water supply and running one of the sprinklers briefly. You may still need to drain some parts of the system manually, such as the backflow device and sprinklers with check valves. When installed correctly in the optimal lawn, this method can be convenient and effective. It will require special valves and for your lawn to have the proper slope to be effective but it requires special valves that may not be compatible with your system.
Blow-out: This method uses compressed air to force water out of the system through the sprinkler heads. You connect an air compressor to the blow-out port of the backflow device and blow out each zone separately. This method is thorough and reliable, but it can be dangerous if not done properly. You need to use the right air pressure and volume for your system, wear protective gear, and follow safety precautions. This is the preferred method and the only method that DreamLawn promotes to confidently protect your system for the winter months.
Which Method Should You Use?
The best method for winterizing your irrigation system depends on several factors, such as:
The type of pipes and fittings you have (PVC or polyethylene)
The depth of your pipes below the ground
The frost level in your area
The availability of an air compressor or a professional service
