How to Winterize Your Sprinkler System

0 Comments

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.
