1. Insulate your system:

• Shut off the water supply to the irrigation system.
• Protect your main shut off valve with insulation.

             (foam insulation tape and/or a plastic bag)

• Insulate above ground piping.

2. Drain the pipes:

• Remove the water from the pipes and sprinklers

3. Protect valves & backflow preventers:

• Insulate backflow preventers and valves if they are above ground.
• Be sure not to block the air vents and drain outlets on backflow preventers (see page 2).
