When it comes time to winterize your RV, the Camco RV Winterization All-Brass Blow Out Plug with Quick Connect aids in removal of residual water from your vehicle's water lines to eliminate the dilution of your antifreeze. Simply open up all your water devices, screw the unit into the city water intake fitting on your RV, and apply up to 50psi of air pressure to blow the lines out before adding your antifreeze for the season.
