Did you know that freezing temperatures are a serious threat to your irrigation system? Do you want to avoid having to make expensive repairs in the spring? If so, now is the time for your sprinkler system winterization so it’s ready during the colder months.

Sprinkler pipes and other parts of the system are at risk of freezing and subsequently breaking when temperatures fall under 32 degrees Fahrenheit. Immediate damage may also occur to exposed sprinkler equipment and pipes during the first freeze of the season. Additional damage may occur as freezing temperatures continue and the wind chill causes the soil to freeze, affecting your system’s underground pipes.

The good news is, there are steps you can take now to prevent damage to your irrigation system and avoid having to make costly repairs in the spring. Keep reading to learn how to protect your irrigation system this winter.

Install Insulation

Shut off the water supply to your irrigations system before the first freeze of the season. Once it’s off, you need to protect the shut-off valve by wrapping it with insulation.

If there is no main shut-off valve call The IDL Company to have one installed. This is a smart preventative step and will help you avoid the need for sprinkler system repairs when warm weather returns.

If there are any pipes for your sprinkler system above ground, they need to be insulated. You can use foam insulating tubes or foam insulating tape for this. An even better method of protection is to bury the pipes, if possible.

Maintain Control of Your Sprinkler System

For automatic sprinkler systems, you must also shut off the timer. Usually, the timer will have a “rain mode” or “off” setting which will turn the signals to the valves off. Using this setting means that the controller will keep time, and the programming information isn’t lost. The only change is that the valves won’t be activated.

If you have a controller that activates a pump, remove the wires connected to “common” and “MV” as a precaution. This will ensure the pump isn’t activated, which may cause overheating.

Drain the Pipes

Since the area is prone to hard freezes in the winter, it’s best to drain your irrigation system pipes completely. There are a few ways you can do this but contacting the professionals for a full blow out is highly recommended to ensure there are no potential issues.

Protect Your Backflow Preventers and System Valves

Make sure you insulate the irrigation backflow preventers along with any exposed valves. You can also use pine straw and insulation tape for this.
