To freeze proof your sprinkler system, begin by turning off the water supply. Then, manually drain the water from the system using the manual drain valves located at the lowest points. For systems equipped with automatic drain valves, these should open themselves once the pressure drops. Don't forget to empty the backflow device. Finally, consider blowing out the remaining water with compressed air, ensuring you do not exceed recommended pressure levels to avoid damaging the pipes. Covering above-ground components with insulation can also help prevent freezing.
FAQs & Answers
- Why is it important to freeze proof your sprinkler system? Freeze proofing your sprinkler system prevents water inside the pipes from freezing, expanding, and causing costly damage or leaks during cold weather.
- What is the best way to drain a sprinkler system before winter? The best way is to turn off the water supply, open manual or automatic drain valves to release water, empty backflow devices, and optionally blow out remaining water with compressed air.
- Can I use compressed air to blow out my sprinkler system myself? Yes, but you must not exceed recommended pressure levels to avoid damaging pipes. It’s often recommended to use a compressor designed for this purpose or hire a professional.
