Winterizing question
I winterized my 5th first by blowing out the water with my compressor then drawing antifreeze through all the lines. I've done the same thing for the last 4 years without issue. I spoke to a couple of...

The "pink stuff" antifreeze does not expand. It's "freeze point" is well below 32 degrees (F). And when it does freeze, it does not expand, it just jells up (gets slushy), but does not expand. If it did, it would be a disaster for us RV owners!
If you use the "pink" you do not need to leave your valves open. I never have. If you "blow" only, then you may want to leave your faucets open, so there is no risk of water droplets freezing in the tiniest of spaces. But I don't think this is necessary either.
I've always kept my sewer blade valves closed with "pink stuff" in the tanks. The purpose for this is to displace any water that might be left in the tank, and also to keep the blade valves wet so they do not dry out. I also keep the cap on the end of the pipe to keep birds from building a nest in there and to keep critters out (like chipmunks, squirrels, and bugs in the Spring before de-winterizing).
Thanks for your reply. I think I was needlessly worried. I haven't had an issue so far and I never leave taps open.
