To ensure your irrigation system remains in good condition, it's important to get into the habit of winterizing it every year. This involves draining the system and turning it off when you're done watering for the season. The main shutoff valve must be insulated with foam insulation tape and a plastic bag to protect it from cold temperatures and prevent freezing. Additionally, any pipes above the ground should be insulated with self-adhesive foam insulation tape or foam insulation tubes.
If you're unsure about how to winterize your sprinkler system, it's best to call a professional. They can quickly and safely get your system ready for spring. The costs of preparing your sprinkler system for winter vary depending on the drainage method needed. When temperatures drop to 30 degrees Fahrenheit, it's time to winterize your sprinkler system.
To do this, start by shutting off the water supply in the backflow prevention device. Then, evaluate the best way to release water from your sprinkler system. This will depend on its design, size, and composition. Generally, you'll need to connect an air compressor to your sprinkler system and expel standing water.
After professionals have ejected the sprinkler system zone by zone, they should also close the main shut-off valves. This way, you won't have to re-program the sprinkler controller when spring arrives. It's important to take measures to prepare your sprinkler system for winter as standing water in the system can freeze and damage components. If you dedicate a little effort to the front end, you could save days of work and incalculable expenses if the sprinkler system breaks down when temperatures drop and winter winds blow.
