Winter is coming, which means it’s time to start preparing your lawn for the cold weather. One of the most important steps in getting your lawn ready for winter is blowing out your sprinkler system before temperatures dip below freezing.

For homeowners who are new to taking care of a sprinkler system, knowing when and how to blow out the lines can be tricky. This blog post will provide an overview of what you need to know about winterizing your sprinklers.

How Cold Should It Be?

Knowing the exact temperature at which you should shut off and blow out your sprinklers can depend on other factors such as climate, sprinkler types, and existing insulation. Generally, experts advise blowing out the lines when temperatures are below 20 degrees Fahrenheit.

However, if you live in an area with colder winters or have a more complex irrigation system, you may want to take additional precautions by having a professional come and winterize your sprinklers earlier in the season.

What Happens If I Don’t Blow Out The Lines?

As soon as an outdoor temperature hits around 32 degrees Fahrenheit, that water may start to freeze and cause damage to the system. Blowing out any remaining water in the lines helps prevent this from happening and allows you to safely store them away until spring arrives.

Otherwise, you could be looking at costly repairs that could have been easily avoided by taking a few simple steps at the end of each season.

Professional Maintenance Each Year is Recommended

For those who are unfamiliar with how often they should be servicing their systems or checking for leaks or damages, it’s always best practice to have a professional come once a year and perform maintenance on all parts of your irrigation system including checking valves, inspecting backflow prevention devices, flushing pipes, replacing worn-out components, etc.

Doing so will help ensure that your lawn stays healthy throughout the year and that your sprinklers don’t experience any damage due to wear and tear over time.

Conclusion:

Homeowners should take care of their sprinkler systems before the temperatures start to drop. Generally speaking, professionals recommend blowing out the lines when temperatures are below 20 degrees Fahrenheit.

However, it is recommended that if you live in an area with colder winters or have a more complex irrigation system you take additional precautions by having a professional come and winterize your sprinklers earlier in the season for optimal protection against damage caused by freezing temperatures during wintertime months.

Taking these steps now will help ensure that your lawn looks great all year round!
