Maintenance Task #1:  Winterize the system (cold climates)

This task involves using compressed air to remove all the water out of the automatic lawn sprinkler system, and shutting off the water supply and the control unit.  If you decide to rent an air compressor to do this task yourself, then consult your user's manual for the correct operating procedure for your system.

Water should be cleaned from sprinkler lines prior to the winter in any region of the country where freezing water temperatures may cause expansion cracking to the system (since water expands when it freezes).

 Maintenance Task #2:  Prepare the system for use (cold climates)

This task involves:

1. Opening the water supply.

2. Checking each sprinkler head and any exposed lines for damage from the winter.

3. Checking the water spray coverage for each sprinkler head

4. Restarting the control unit.

Preparation for operation.

Please note that blowing out your system can be potentially dangerous, and you should take adequate precautions to ensure proper eye safety and to avoid physical injury from flying debris. You need to also be careful not to over-pressure your system.
