Easiest method: drain the tank, then pour a gallon of RV antifreeze into the freshwater tank, open taps one at a time until pink flows. In the spring drain the tank, put a few gallons of freshwater in and run each tap until not pink. If OCD, do it three times. Or carry drinking water in jugs.
I drain the tank, disconnect it’s connection to the pump so water in the tube falls into the tank and drains. I use a 2 position valve to connect the pump input to a tube going to a jug of RV antifreeze. After running every tap, I use a clear tube (I always have it on the tank drain to show water level) and funnel to get a Liter of antifreeze into the tap (vulnerable to freezing) and low point in the tank.
