You will have to run water into the tank and let it drain out the drain cock, and keep repeating a number of times. It helps to tilt the front of the trailer down to get most of the water to drain toward the outlet. Next time you winterize, if you don't already have it, add a winterizing hose to the system. It eliminates putting antifreeze in the tank and saves on antifreeze as well. You will also want to sanitize the tank by putting about 1/3 cup of plain Clorox in the tank and filling with water. Run that solution through the system and let it sit a few hours then flush a couple of times. Then enjoy!
