The best

Been using this for my camp house for years. Sometimes temps can drop to minus 30F. Even though I blow out the pipes with compressed air and wet vacuum the drains. Small pockets of water can still collect in various joints, fittings and pumps. I pump thr AF thru the entire water system and run the washer and dishwasher. Being it is rated minus 100, even if it gets diluted in particular spots I don't have to worry about expanding ice. Don't get me wrong , minus 50 is good too , it will turn solid but not expand. The minus 100 stuff just gives me piece of mine protecting my pipes, appliances, mixing valves and drains.

Good

I use this in my pressure washers when I put them away for the winter. Never know how much water is really in them. Better safe than sorry.
