2019 Forest River Hemisphere Elite WINTERIZE
My first winterizing this model was a huge pain. Followed all instructions and didn't work. The correctly installed winterize kit just needed the bypass valves and turn water pump on to suck the antifreeze straight out of bottle. If you do everything perfect and it still doesn't work take the panel in thru storage off that has the water filter attached to it, also has access to water pump. Look at the winterize water line inside the panel. Mine was 6 foot long inside that tight space and had 4 kinks in it that stopped suction from antifreeze bottle. If your winterize antifreeze line doesn't reach the ground you may have same problem.
