I called the dealer. They use the anti-freeze method for winterization (vs just draining) so they believe they have it covered. I asked about if you were just to drain and the response was "I guess you could disconnect the hose and blow some air in there". Not very convincing. I also asked about the name of the manufacturer and they did not know - "We just order the parts through SC". Was hoping then I could contact the manufacturer. Also emailed SC - no reponse.
