Your in-ground sprinkler system can be an important part of your garden’s health and beauty. But during the winter months, when temperatures drop, it’s important to remember that your sprinkler system needs some special attention before the cold hits.
Continue below to review a quick and easy guide to blowing out your inground sprinkler system for winter, plus where to get the best seasonal plumbing service near you.

Winter Maintenance for Underground Sprinkler Systems
Blowing out your inground sprinkler system is one of the best ways to protect your pipes against freezing and can help you avoid costly plumbing repairs come springtime. Here are the simple steps to getting the job done right the first time, every time:
How to Blow Out an In-Ground Sprinkler System:
The first step in blowing out your inground sprinkler system is to locate the main water shut off valve. This will usually be located close to where the water supply enters your home. Once you’ve found this valve, turn it off completely until spring when you’re ready to use your sprinkler system again.
Next, you’ll need to connect a garden hose to one of the last sprinkler valves in your system. Run the other end into an area where it can safely drain without causing any damage (such as a grassy area). Finally, turn on all your sprinkler valves, starting with the first one closest to the main water shut off valve.
Once you’ve done this, turn on an outside faucet and let it run until nothing but air comes out of your sprinkler system pipes. This will help clear the remaining water from your pipes and ensure that they don’t freeze during the winter months. Once you’re done with the faucet, turn it off and close the shutoff valve you opened earlier.
