Winterizing

[Gould2749]

I have blown out the lines (I think), dumped the black/gray tank and put a cup of antifreeze in the toilet and P trap. Is it advisable to put some antifreeze in the heater ( I did purge the heater to the best of my knowledge) and in the black/gray tank? I have a 2017 Sport.
Thanks for the help all.

The heater shouldn’t need it — and I’ve heard the stuff would be hard to purge when you dewinterize.

I wouldn't leave the RV AF in the toilet bowl. It's better to use silicone grease on the the seal and leave the bowl empty.
Our seal failed after several Winters of AF in the toilet.

This is also an option. Pour a bit in and leave it.

How about putting some anti freeze in the black/gray tank?
Thanks again.

I don't, never have. Just drain completely.
Anything laying on the bottom that could freeze won't expand enough to the damage the tank.
