Partial un-winterization

[DaveT]

My camper is fully winterized using antifreeze. Normally, to un-winterize I would add water to tanks, flush through all pipes (several times), chlorinate the tanks, flush with that water, more fresh water, and done.

I'm camping this weekend in a park with water hookups. So I want to flush everything EXCEPT the tanks and pump using city hookup, enjoy the weekend, the "re-winterize" using pressurized air to get water out of all lines EXCEPT the pump and tanks.

The key here are the excepts. If I use city water, and put none in the FW tanks, and don't use the pump, then my assumption is that the existing antifreeze will remain there (mostly the pump) and even re-winterizing via air won't remove it.

Is there any flaw to my logic?

Thanks

Your logic makes sense to me. I’m interested to see if anybody has a different opinion. Good luck.

I see no reason why it would affect your FW tank or ur pump because your not using it.
