Winterizing A frame hardside

[QUOTE=5picker;2646632]One last point for those that only blow out...
Blowing out the lines with compressed air does not address the water pump or the suction/strainer screwed to the inlet side of the pump.

My tt has black tank flush line routed up hill to the vacuum breaker, then is routed vertically to the black tank. I've use compressed air only. No antifreeze.The initial purge has water but diminishes to air only.

Your Thoughts ????

Minutes, not seconds.
