Unfortunately its the time of year to winterize my pup. I usually connect a hose to my inlet valve of the water pump and struggle to pump anti freeze through it that way. My hose is homemade and leaks and doesn't work that well. Does anyone have a solution that works well for them? I've seen these kits but don't know if they are the best solution: https://www.amazon.com/Camco-36543-Pump-Converter-Winterizing/dp/B0006JJ588 Thanks!
