My RV Pump Converter Winterizing Kit (Camco/RV) is installed between the fresh water tank and the pump. I disconnected the incoming fresh water suction line from the pump, then installed a brass valve with 1/2" male thread to suction opening on the pump. Finally reconnected water line to the brass valve with female adapter provided in kit. There is a cap on the brass valve which is removed and a clear hose with fitting is attached to the valve and the other end goes into a gallon of RV winterizing antifreeze. I just turn the brass valve handle 1/4 turn turn on the water pump, switch on the pump and turn on each faucet one at a time to allow antifreeze to run through. I let about a cup drop into drain to protect traps. When all faucets (and toilet) are done, just remove clear hose and replace cap on valve. My fresh water tank is under front bench seat of dinette along with the pump. My hot water heater already has a by-pass installed so I just drain the fresh water tank and water heater and then set valves for by-pass before I start all this. In the spring, I sanitize fresh water tank and flush system with fresh water. Then reset by-pass valves to water heater and it's good to go. It's really a painless way to winterize water lines without getting nasty tasting antifreeze into any water tanks.
