Using the winterizing port
I was wondering, Is the winterizing port on the rear of my 2806BS only for hooking up the air compressor to blow out the lines? If so (or not) how does one run antifreeze into the lines? I use to take off the water pump feed and hook it up to a gallon of antifreeze.
Thanks in advance
