Frozen RV "pink stuff" is perfectly normal. The problem: You can't tell if you've displaced all the water that was in the system, so there's a chance the water will freeze. Hopefully there is enough antifreeze mixed in that the expansion of the water won't be so great as to cause damage. Which is another reason to use air to blow as much water from the system as possible before adding RV pink stuff.......

Hi John,
I was going to add RV Antifreeze to my black and gray water before i go to Quartzsite because i was afraid my tanks (located under my RV) may crack if it freezes? But now Im wondering if that is ONLY used when you are winterizing your RV for storage? Never had a problem before when I owned my lazy daze but am concerned with my new Class C winnebago as the factory told me to leave if it gets
that cold???
