We have 2018 2552. We have the four way toggle for fresh water fill, city water, tank water using the pump and winterize. We also have the water connection in the macertor pump section on the rear driver's side. There are two valves labeled grey tank flush and black tank flush. I never winterized those two valves. I did not see anything in the PC info I received that showed a need to put antifreeze in there. We drove down to Florida on January 27. I tried flushing the two tanks. When I turned on the valve for the black and grey tank, as I did in the fall, each time there was some flushing sounds from each of the tanks. But there was also spraying water the back side of the valves. It looked like there may be a rupture either on the hoses connected to the tanks or something else. I have not been able to get under the coach to see what was leaking. Too hot here. Will check underneath when we return home in a couple of weeks. I am concerned that something did rupture especially since we had some very cold weather in NE Pa in December and January. One thing I know for sure is that typing a long paragraph using a "smart" phone is stupid. Took me more than half an hour.
