Our pump has a tee on the suction side. One line goes to the FW tank and the other is a clear vinyl hose open at the end. Each has a shut off valve to control which one is being used. Very easy to put antifreeze throughout and in the pump, too.
^^^ Ditto, I have never put any antifreeze in the fresh water tank. I open the drain valve and let it all run out, I have never had a problem doing this. I put the open pump inlet hose directly into the container of antifreeze and let the pump do all the work. I start at the furthest faucet from the pump and work my way to the front. Dont forget the outside shower if you have one! Winner, Winner, chicken dinner.
