Another winterizing question

[jcar6109]

Our coach like a lot of them has the black tank flush system with the water line connection in the water compartment to flush the inside of the black tank. I don't know if this drains into the tank when not used or if there is a trap to prevent odors.

Do I need to get antifreeze in this line somehow? Or would it be best to blow this one with an air compressor.

I just blow it out, and hav'nt had a problem. Of course I never thought of blowing out on our first MH and never had a problem either!

Have never done anything to it. Never had a problem. Maybe I am just lucky.
