This winterization kit worked well once adapted to winterize my RV. The kit has everything you need to run antifreeze from the reservoir through a hose to your water pump bypass valve, where you can then pump it though all of your RV water lines. Durable plastic with all of the fitting required to adapt it to fit an RV water system and it comes with a 6ft hose.  Makes winterizing your RV so much easier.  See my use and review in Tech Tips Winterizing your RV
