Review on ❄️ Winterize Blowout Adapter Kit by BingSnow by Ronggolawe Denney

I restored a used touring camper (2000 Viking). Prepared for the winter, and although I merged it. This adapter was small and I didn't want to get water damage that I overlooked. Hooked it up to the van and turned the valve off. I attached an air line to it and slowly opened the valve and water flowed out of the bottom drain and sink. I added RV antifreeze and pumped it through the water supply system. I'm glad I drained more water before adding antifreeze.
