How to Winterize Sprinkler System in Texas
Winterization is an essential process to prepare your sprinkler system for cold weather. It involves draining and blowing out the water in your system to prevent the pipes from freezing and bursting. If you live in Texas, you may think that your winter is not as severe as other areas. However, even in milder winters, some frost and ice can still form, which can damage your irrigation system. In this article, we will guide you through the steps on how to winterize your sprinkler system in Texas.
Why Winterize Your Sprinkler System in Texas?
Texas winters can be unpredictable, with occasional extreme cold snaps. These unexpected weather events can wreak havoc on your pipes and sprinkler system. When water freezes in pipes, it expands, causing them to burst. The damage caused by frozen pipes can cost you hundreds or even thousands of dollars to repair. Winterizing your sprinkler system prevents the water from freezing and causing damage. Moreover, winterizing your sprinkler system can also extend its lifespan, saving you money in the long run.
Steps to Winterize Your Sprinkler System in Texas
Step 1: Turn Off the Water Supply
First, turn off the water supply to your sprinkler system. This can usually be done by shutting off the main valve that supplies water from your home’s water line. If you are unsure of where the valve is located, consult the owner’s manual or seek professional assistance.
Step 2: Drain the System
Next, open all the valves in your sprinkler system to allow the water to drain. This includes the drain valve or petcock, located at the lowest point of your system. After opening this valve, leave it open until all the water has drained out of the system. Remember to turn off the drain valve once it has emptied.
Step 3: Use an Air Compressor
After draining the system, use an air compressor to blow out any remaining water in your sprinkler system. Connect the air compressor to the mainline of your system, where the water supply valve was located. You will need a fitting to connect the air compressor nozzle to the sprinkler system. Slowly increase the air pressure and work your way through each zone of your irrigation system, one zone at a time, until all water has been blown out.
Step 4: Check the Valves
Check all the sprinkler valves to ensure they are fully closed. Any open valves can leave space for air to enter the system, causing damage during the winter. You may also want to consider installing insulation sleeves around the valves that are located above ground to protect them from sudden temperature changes.
Step 5: Winterize Your Backflow Preventer
If your sprinkler system has a backflow preventer, it is crucial to winterize it as well. Backflow preventers are typically located above ground and are vulnerable to freezing temperatures. To winterize, start by shutting off the main water supply valve to the backflow preventer. Then, open the valve closest to the backflow preventer to remove all the water from it. Next, lift the test cocks on the backflow preventer to release any remaining water inside. Finally, close the test cocks and reattach the caps.

Winterizing your sprinkler system in Texas is a crucial process to prevent damage caused by freezing temperatures. By following these steps, you can save money in the long run and extend the lifespan of your irrigation system. Remember to turn off your water supply, drain the system, use an air compressor, check the valves, and winterize your backflow preventer, if applicable. If you have any questions or are unsure, seek professional assistance. By properly winterizing your sprinkler system, you can ensure it will be ready to use again in the spring.
