If its anything like our 2400WS, the city water has a check valve at the connection point and also a check valve so that it can't back up into the Fresh water tank.
The fresh water tank has a drain, there should be two other capped lines in the access hatch. One is for the hot water line, the other for the cold water. to winterize, you need to open all three and the faucets for a complete drain. Our 2400W also has a winterization valve located in the shower. This valve has a capped hose hooked to it on one side and the water feed line hooked to the other.The hose itself is located behind a trim panel. just take out the screws holding the panel in place to access it.
By placing the valve in the winterization position, the valve opens so that you can either use an air compressor with a home made adapter to go from the air hose to 1/2" male pipe to blow air through the system and thus winterize it. You can also put a funnel on the end of the hose and pour red pop(RV antifreeze) into the system.
Hope this is of some help
