Go to the Files section and click on Sunline Guides and Tips. You will find a winterizing guide there that has complete info on purging the water system so you can do your repairs.
It's also a complete winterizing guide so you should be able to do this yourself. It's really an easy job.
Also, you might want to search on "winterizing" (without the quotes) in the Repairs and Maintenance section. There are many good posts about winterizing tips and tricks there.
