I have a 351rlts,what I am trying to say is why cant i just unhook,bypass the hot water and pump anti freeze in after draining lines and turning pump on without switching to winterize,the antifreeze will still go through all the lines just like city water does when hooked up,i just dont understand what the difference is between city fixtures and winterize on the control panel, what exactly is the difference and what does it change,thanks for helping me understand
