Introduction:

As temperatures begin to drop and winter approaches, it’s essential to prepare your sprinkler system for the cold season properly. Failing to winterize your sprinkler system can lead to costly repairs and potential damage due to freezing pipes and expanding water. In this article, we will discuss three methods for winterizing your sprinkler system to ensure its longevity and proper functioning.

1. Manual Drain Method:

The manual drain method is suitable for sprinkler systems with manual drain valves located at the lowest points of the irrigation piping network. To perform the manual drain process, follow these steps:

a. Turn off the main water supply to your sprinkler system.

b. Open all the drain valves and allow the water to flow out completely.

c. Once drained, close the valves again.

d. It is also advisable to remove any above-ground sprinkler heads and protect them from freezing temperatures.

2. Automatic Drain Method:

If your sprinkler system is equipped with automatic drain valves, you can use this method for winterization. This process makes use of the natural flow of water in pipes to drain excess water after each watering cycle. Here’s how:

a. Shut off the main water supply.

b. Activate a zone on your irrigation controller briefly, which will cause the automatic drain valves in that zone to open.

c. Once you observe water draining from the valve, move on to the next zone and repeat until all zones are completely drained.

Note: This method may not work effectively if some valves are not operating correctly or if certain areas in your lawn have poor drainage.

3. Blow Out Method:

The blow out method involves using an air compressor to force any remaining water out of pipes and components, making it a popular choice for professional landscaping services. To utilize this method:

a. Turn off the main water supply.

b. Connect an air compressor to the system via a quick-connect fitting or a hose bib connection.

c. Starting with the zone furthest from the air compressor, activate one zone at a time, allowing air to push out any remaining water.

d. When water has been blown out completely, move on to the next zone and continue until all zones have been cleared.

CAUTION: The blow out method can be dangerous if not performed correctly. It is recommended to seek professional assistance or use proper safety measures when using an air compressor to avoid personal injury or damage to your sprinkler system.

Conclusion:

Winterizing your sprinkler system is essential for preventing damage caused by freezing temperatures. By using one of these three methods, you can ensure your sprinkler system remains intact and functional, ready for use when the warmer months arrive. Don’t forget always to follow necessary safety precautions and consult professional help if needed.
