The deep freeze of the Northwest may not be here, yet. But winter is coming. Now’s the time to get your sprinkler system ready for colder months ahead.
4 steps to winterize
- Turn off the water supply to your sprinkler system.
- Drain any remaining water from the pipes. Do this by opening the manual drain valves or using compressed air to blow out the water.
- Insulate any above-ground pipes to prevent freezing. You can use foam insulation.
- If you have a backflow preventer, make sure to drain it as well. This device prevents water from flowing back into our water supply, so it’s important to keep it in good shape.
