Guidance for Properly Deactivating the Irrigation System Before Winter Arrives
Shutting Down Your Irrigation System Like A Pro: A Winterizing Guide For Sprinkler System Owners
December 7, 2023
Winter's chill is just around the corner, but before the cold sets in, it's crucial to winterize your automatic sprinkler system, including smart irrigation systems, to keep it in tip-top shape for the spring growing season. Follow these steps to ensure your system stays snug and safe all winter long.
The Winterization Process
1. Shut Off the Water Supply
Locate the water supply valve, usually found in the basement or near the water meter, and turn it to shut off the water supply to the sprinkler system. Check if you have a gate/globe valve or ball valve and proceed accordingly.
2. Insulate the Main Valve
Use insulation material like foam covers or heat tape to protect the main valve from freezing temperatures during the winter months.
3. Drain the System
If manual drain valves are available, open them to drain the water. For automatic drain valves, ensure they're functioning correctly. The most effective method, particularly for preventing freezing and bursting, is using an air compressor to blow out water from the pipes, valves, and sprinkler heads.
4. Take Care of Timers and Controllers
Smart irrigation systems should be disabled or set to winter mode, if available, to keep monitoring capabilities active during the off-season (but with water flow shut off). Manual timers should be set to the "off" position.
5. Tend to Solenoids and Valves
Ensure solenoid valves are fully closed and not leaking, and electric solenoids are de-energized. Drain valve boxes, checking for standing water and ensuring there are no remaining droplets.
6. Check Sprinkler Heads and Filters
Remove and clean sprinkler filters if present, and clear any debris or blockages from sprinkler heads. Ensure all filters are spotless and clog-free for efficient water flow come springtime.
7. Final Check and Documentation
Perform a thorough inspection of the winterized system and make a record of the process for future reference.
Tips and Tricks
- Hire professionals if you're unsure of any aspect of the winterization process.
- Plan a spring check-up to ensure the system is ready for operation and to repair any damage that may have occurred during winter.
By winterizing your automatic sprinkler system, you can keep it in excellent condition, welcoming the return of the growing season in the spring!
- In the home-and-garden category, winterizing your smart irrigation system is an essential lifestyle practice to maintain it in optimal condition for the spring gardening season.
- After draining and insulating your irrigation system, don't forget to adjust your timers and controllers to winter mode or set them to the 'off' position for the off-season, ensuring they're prepared for the spring gardening season.
