Winterization Drain Valve Residential Fridge Itasca Ellipse

The instructions are saying that you need to pump RV anti-freeze through all of the lines and should appear in the ice maker compartment itself while making ice. Once your ice is pink and won't freeze you have completed the process. IMHO, a better option is to blow out all of the line including the ice maker with an air compressor set at about 50 psi.
