I have a basement so everything drains by gravity.Re: Winterizing & Summerizing for SnowbirdsWe put RV antifreeze in all the traps and in the toilets and washer. I run the dishwasher and clothes washer on rinse with antifreeze in the bottom. I drain all the water out of the pipes and water heater. That way if the heat goes off I have no damage. Lost the heat last winter and no damage.
