As the temperature starts to drop and winter sets in, homeowners should take a few moments to consider how they can protect their seasonal lawn sprinkler systems from freezing water.

One of the most effective methods for doing this is by blowing out your system with an air compressor or electric shop vac. But what are the benefits of this home maintenance task?

Let’s take a closer look.

Benefits of Blowing Out Your Sprinkler System

The primary benefit of blowing out your sprinkler system is that you will save money on costly repairs and replacement fees associated with frozen pipes.

By taking the time to blow out your seasonal lawn sprinkler system before cold weather sets in, you can ensure that all water has been removed from your pipes, eliminating any chance of it freezing inside them and causing damage.

Additionally, regular maintenance like this helps to extend the life span of your sprinklers and keep them in good working condition for years to come.

In addition to saving money on repairs, there are other benefits associated with blowing out your sprinkler system such as improved efficiency and performance.

By cleaning your pipes regularly, you can ensure that they remain free of debris which can clog up water flow and reduce overall efficiency.

In addition, regular maintenance like this also means that all components are kept clean, allowing for optimal performance when your system is running again in the springtime.

Finally, blowing out a seasonal lawn sprinkler system is relatively easy and can be completed quickly using either an air compressor or an electric shop vac (depending on size).

This makes it an ideal task for busy homeowners who don’t have a lot of time to spare on home maintenance but still want to keep their systems running efficiently.

What You Need To Blow Out Your Sprinkler System

The good news is that blowing out your sprinkler system isn’t difficult. All you need to do this job is a small air compressor or electric shop vac. If you already own one of these tools, great!

If not, you can often rent them for a day from your local hardware store; even better if they offer free delivery! Just make sure it has enough power and capacity to do the job correctly.

Step-by-Step Instructions for Blowing Out to Prevent Costly Repairs

  1. Start by turning off the main water supply and draining any remaining water in the system using a hose or pipe bib—this will ensure there’s no water left in the pipes that could freeze and cause damage over winter.
  2. Next, disconnect all hoses and other attachments connected to your sprinklers or valves—you don’t want any remaining pressure in these attachments when you start blowing out the pipes.
  3. After that, attach your air compressor or shop vac to each valve and blow out each pipe until all of the air has been expelled and no more water comes out (make sure to wear protective eyewear). Repeat this process for each valve on your system until all of the pipes have been blown out completely.
  4. Finally, turn off the power supply and disconnect all hoses/attachments from each valve before storing them away for winter storage (or until next spring!)
  5. And remember: always follow safety guidelines when working with electrical appliances like an air compressor or shop vac!

In summary, it’s important to blow out your seasonal lawn sprinkler system once a year before cold weather sets in so as not to damage any of its components with freezing water!

Doing so will help prevent costly repairs or replacement fees down the line – so why not give it a go?


In conclusion, there are several key benefits associated with blowing out the sprinkler system before cold weather sets in – namely preventing expensive repairs due to frozen pipes as well as improved efficiency and performance once springtime rolls around again.

Plus, it’s a relatively simple task that doesn’t require much time or effort so anyone can do it! So don’t wait until it’s too late – take some time now to check up on your seasonal lawn sprinklers and make sure everything is running smoothly!
