Materials You’ll Need
- Screwdriver or wrench
- Rags or towels
- Bucket or container
- Anti-freeze solution (optional)
Step-by-Step Instructions
1. Turn Off the Water Supply
Locate the main water valve for your sprinkler system, typically near the street or in a utility box. Turn off the valve by rotating it clockwise.
2. Open Faucets and Sprinkler Heads
Open all faucets and sprinkler heads on the system to release any remaining water. Use a screwdriver or wrench to open the bleed valves on the sprinkler heads.
3. Drain the Backflow Preventer
Locate the backflow preventer, a device that prevents water from flowing back into the main water supply. Open the drain valve at the bottom of the backflow preventer to allow trapped water to drain.
4. Disconnect the Controller
Unplug the sprinkler controller from the electrical outlet. Remove the controller from the mounting bracket and open the housing. Disconnect the wires from the terminals.
5. Blow Out the Lines
Connect an air compressor to the blow-out port on the sprinkler system manifold. Turn on the compressor and adjust the pressure to 30-40 psi. Open the valves on the manifold one at a time to blow out the water from the pipes.
6. Add Anti-Freeze (Optional)
If you live in an area with extremely cold temperatures, consider adding anti-freeze solution to the sprinkler lines. Follow the manufacturer’s instructions on how to dilute and apply the solution.
7. Inspect and Clean
Inspect the sprinkler heads and filters for any damage or debris. Clean or replace them as needed.
Tips for Winterizing Your Sprinkler System

Troubleshooting Common Problems
- Leaking sprinkler heads: Replace the O-rings or seals on the sprinkler heads.
