Just blow it out with low pressure. I just hook up a small hose and manually blew it out last year as I forgot about it till last minute. It pretty well drains empty by itself anyways.
It was a rainy few days at Algonquin Prov park...tarps kept us dry.

Good idea. I'm just in the process of winterizing my unit so after a good hot and cold water combo flush I blew out my flush kit with the compressor, done deal and that was a great tip to keep in the memory bank. Thanks Harley !!!
