2015 jayco 28bhrb winterizing questions

[Brad1161]

Do i need to put antifreeze in the black tank flush connection or the city water connection? I pulled the grey water handle till i seen some pink come out do i need to to this for the black water valve also? I do have the blue chemical in the black tank along with antifreeze

I never have put antifreeze in those ports and have never had a problem.

After I blow out all the water (don't forget to open the outside shower valves if you have one), I dump a cup of AF in each drain and also some down the commode.. I like to leave more in the black tank so it won't dry out so much. Water heater is emptied but no AF in that.
Happy RVing,
Jeff

Just blow it out if you are worried, no point for antifreeze.
