Winterizing Your Lawn Sprinklers
There are three basic methods for draining leftover water from your sprinkler or irrigation system: manual drain, automatic drain, and blow-out. The method you use depends on the type of irrigation you have in place. If you’re not sure or don’t feel comfortable winterizing yourself, contact a lawn sprinkler installation professional for help. Keep in mind that you won’t be alone in requesting assistance, so plan ahead. Prepare early when you live in a region where frost penetrates deep underground.
Manual Drain Method
Some irrigation systems are equipped with manual drainage. These systems allow you to empty excess water from the system by simply opening a valve. Some sprinklers are equipped with check valves. These devices allow water to only flow one way. If you’ve got check valves on your system, try raising the sprinkler heads. This should let water drain out of those mechanisms. Once you’ve drained the entire system, close all the valves.
Automatic Drain Method
An auto drain system has valves that automatically drain water from the pipes. This happens only when the water pressure falls below a certain number of pounds per square inch. You may still need to drain the water between the shut-off valve and the backflow device. If the sprinkler heads are equipped with check valves, empty them separately.
Blow-Out Method
The final way of draining an irrigation system is known as the blow-out method. To drain the pipes, you force compressed air through the irrigation system. This discharges excess water through the sprinkler heads. It works if you have the proper irrigation system to handle the pressure. The blow-out method is potentially hazardous. It can damage both the irrigation system and the person attempting it. It’s vital to take proper safety precautions when using this method. If you’ve never worked with compressed air or blown out an irrigation system before, please consult a professional. You’ll save yourself from frustration, possible injury, and repair costs.
