How to Winterize Your Sprinkler System

sprinkler watering the lawn

Lawn care can be tricky to maintain during the winter season, as the cold temperatures are set on freezing or destroying your green yard. It’s hard to know exactly when the cold spells will hit, too; some winter weather can start as early as November, while some temperatures don’t truly drop until after New Year’s. It can be difficult to figure out when your sprinkler system needs to be maintained, and when it should be shut off completely.

Winterizing your sprinkler system is crucial for the survival of your water pipes. When winter strikes, you must ensure that all of the water is blown out of your systems. Without removing the water from your pipes, they will freeze on the inside and will cease functioning. This can cause an excess of pressure buildup, or it can stop your water systems from working entirely.

If you’re ready to prepare your yard for the cold season, here’s how you can winterize your sprinkler system and prevent any permanent damages.

What You Need

You’ll need a couple of tools at your disposal before you can begin winterizing your sprinkler system. Whether you’re looking to do it yourself, or you want to hire one of our Lawnscape professionals to help you out, here’s what tools and materials you need to get started:

● Air hose

● Air compressor

● Hose adapter (Preferably with quick-connect capability)

It should take only a few moments to set up your compressor and clear all of the water from your sprinkler system. Double check to make sure you have all the required materials before you begin work. As soon as your valves are off, it’s time to get to it!

Close Your Valves and Apply the Compressor

The first thing you need to do when you access your sprinkler system is to locate the valves. There should be two valves on your backflow preventer. Make sure these valves are completely turned off before you move on to the next steps.

The blowout port should have a plug, which needs to be removed as well. From this open hole, you should be able to screw in the hose adapter. Again, this is best completed with a quick-connect hose adaptor. Snap this on, and then connect the open end to the compressor.

Use the Compressor to Clear Water

With this method, your compressor does all of the heavy lifting. Once your quick-connect establishment is set up, you can use the compressor to clear water by each zone. Keep in mind that compressors can’t blow out the entire system at once, even if you purchase the largest and most powerful one. But they do a pretty great job clearing out water zone by zone.

The compressor should be set to 80 psi if you’re dealing with PVC pipes. If you have newer, more flexible polyethylene pipes, you can set the compressor to 50 psi. Before you turn on the compressor, make sure to turn off your water supply. You should also make sure that just one zone is open at a time.

Open your manual drain valve at the active zone and connect your airline to the blowout port. The other end should be fixed to the compressor. Once your sprinkler heads pop up, they will start shooting water everywhere. Make sure to keep a close eye on the sprinklers, for as soon as they dry out, you want to remove the hose. Don’t keep the hose on them after they’ve gone dry, because they run the risk of melting.

Move on to the next zone and repeat the process! It is suggested to blow out each zone twice, just to be sure that all of the water is completely removed.

Preparing Your Lawn for Winter


When winter finally hits, it’s important to make sure your lawn doesn’t suffer irreparable damage. Harsh weather conditions such as snow, ice, and frost can harm the integrity of your lawn and make professional lawn care seem like an uphill battle. Read on to discover a few ways to protect your lawn and grass and avoid dealing with any adverse, long-term effects.

Prepare Ahead of Time

Never wait for winter to arrive before taking the necessary steps to protect your lawn because, unfortunately, the damage will have already taken place. It is best to prepare your lawn for winter during the autumn season. This will ensure your lawn is in good condition before the first freeze hits and your lawn goes dormant for the winter season. You can take steps to protect your lawn in a number of ways. Clear your lawn of any debris including excess leaves, mulch, lawn equipment, gardening tools, and toys. Raking leaves away will help to avoid wet spots from appearing which can harbor mold and moss.

When your lawn finally goes dormant for the winter season, you will want to keep it clear and deter others from stepping on it as this can corrupt the grass’ integrity and cause injury. Replace any unhealthy grass plants and reseed your lawn before the weather gets too cold in order to fill any patches that may have appeared. Aerating your lawn in the fall also allows nutrients, oxygen, and water to reach soil and permit cold weather seeds the chance to sprout.

Restore Lost Nutrients

As the weather cools down, it is important to replace any lost nutrients that may have been depleted during the summer months. Put aside time to fertilize and apply mulch to your lawn to offer it a chance to flourish once again. A simple way to apply mulch is by utilizing fallen leaves which tend to gather in autumn. Simply shred them by running over them with a lawn mower.

Mow Your Lawn

Another important aspect of lawn care during the winter is to mow your lawn regularly. Keep your grass shorter than you normally would to ensure that rodents such as moles and gophers do not make a home there and ruin your lawn. Keep in mind that your grass will also be growing more slowly as it lies dormant in the winter time. Avoid mowing your grass too short all at once as this can shock the grass, damaging it greatly. Instead, slowly and gradually cut your grass shorter each time. Beginning in the fall, mow your lawn regularly, lowering your mower blade slightly each time.

Weed Control

Although beige, dormant grass tends to be unappealing to most, it can be helpful for a number of reasons. The main reason is that weeds tend to sprout green. This makes them quite easy to identify and then get rid of. It is paramount that you do not pull the weeds by hand as removing their roots will be fairly difficult during the winter. Instead, employ help from a grass-friendly herbicide treatment to kill any weeds that pop up and also protect the grass.
