Champion Forest Irrigation Winterization Guide
Protecting your irrigation system from sudden hard freezes is a vital part of home maintenance in Champion Forest. While our Texas winters are generally mild, the Houston area is notorious for unexpected, sharp drops in temperature. Preparing your sprinkler system by late November helps prevent cracked pipes, broken valves, and costly spring repair bills.

Tools and Materials You Will Need
Gather these items before you begin:
- Pliers or a wrench (if required for your specific water valve)
- Foam pipe insulation or fiberglass insulation tape
- A backflow preventer insulation cover (often called an insulation pouch or blanket)
- Duct tape or zip ties
Step 1: Turn Off the Water Supply
Locate and close the main shut-off valve for your irrigation system.
- Find the valve. It is usually located near your water meter, or right next to your backflow preventer.
- Turn the handle so it sits perpendicular to the pipe. This stops water from entering your irrigation system.
- Make sure you protect this valve from freezing temperatures by wrapping it with insulation tape.
Step 2: Drain the Pipes
Remove the remaining water trapped inside the pipes to ensure they do not expand and burst when temperatures drop below freezing. Depending on your system, you will use either manual or automatic drain valves.
- For Manual Drain Systems: Open all the manual drain valves located at the ends and low points of your irrigation piping. Let the water drain out completely, and then close the valves securely.
- For Automatic Drain Systems: Briefly turn on one of your sprinkler zones from the controller while the main water supply is off. This relieves the water pressure in the pipes, allowing the automatic drain valves to open and empty the system.
Step 3: Insulate the Backflow Preventer and Exposed Pipes
Wrap your above-ground equipment to shield it from icy winds and freezing temperatures. The backflow preventer is the most vulnerable and expensive part of your system.
- Wrap all exposed pipes with foam pipe insulation or fiberglass tape. Secure the insulation with duct tape or zip ties.
- Slip a dedicated insulation pouch over the backflow preventer.
- Check that you do not cover the drain ports or air vents on the backflow preventer, as it needs to function properly if pressure builds up.
Step 4: Update the System Controller
Adjust your automated sprinkler timer to reflect the winter season.
- Locate your irrigation controller and turn the dial or switch to the “Off” or “Rain” setting.
- Use the “Rain” setting if your controller has one, as this stops the system from watering but keeps your programmed schedule saved for the spring.
Taking an hour to winterize your irrigation system safeguards your Champion Forest home against unpredictable Texas winter freezes. By shutting off the water, draining the pipes, insulating exposed equipment, and updating your controller, you protect your landscape investment and save yourself from dealing with severe water damage. Stay warm, and rest easy knowing your system is secure until spring.
