Today I flushed my RV with the pink antifreeze rated at -50 full strength on the jug. I did it the same as always used the camper pump to pull the pink stuff threw the system then I realized I was going threw much more than normal. I had the bathroom hot water faucet on or open so the pink stuff was just poring out then I ran out. So my question is if the sink line was flushed with pink antifreeze but it is no longer in the line and obviously no water as well do I have to get more to fill the line or will it be fine if the line is empty but was flushed with pink stuff?
