Every fall, we'll take the following steps to protect your system from the Michigan winter:

• Turn off the water at the supply and tag the shutoff valve
• Drain the plumbing
• Evacuate all water in system using compressed air at a safe operating pressure
• Unplug the controller and remove the battery backup
• Make notes of any problems that will need to be addressed in the spring

All completed winterizations performed by Precision will be backed by our freeze guarantee unless one of the following conditions exists:

• Gate valve used for shutoff
• System winterized after the first night of freezing temperatures
• Precision does not perform the subsequent spring startup
• Homeowner shut off the water supply
