Answer: 
It freezes at 8 degrees F but does not expand until below - 50 F. The expansion is what causes the damage to lines and tanks. There is also a different grade that freezes lower and does not expand until -100 F

Answer: 
With mine I disconnect the freshwater tank from the pump and then use the pump to pump it through the lines. You could also use a handpump and pump it through the city hookup.

Customer Reviews

South/Win RV Antifreeze with DOWFROST is rated 4.2 out of 5 by 6.
Rated 5 out of 5 by from Works GREAT& Better for Environment! I have used Dow Antifreeze for 5 years now to winterize our homestead cabin in Wyo(at altitude of 8,000-gets VERY cold out there). Has worked beautifully. Changed over from using standard antifreeze- as this is better for the Eco-System. I highly recommend this product. Haven't had any broken lines, toilet issues at all. And it's easy to do, very affordable. I'm a very satisfied customer.

Rated 5 out of 5 by from Dowfrost antifreeze I have used this product in our 3 pools for the past few years now. A 70,000 gallon pool, 2,000 gallon spa and 2,000 gallon baby pool. I suck out the skimmer lines and water fill lines of as much water as I can get out and pour 2-3 gallons in each and never had a problem yet and our pools are 25yrs old concrete in-ground pools. I also use it to winterize the pump baskets and out door bathrooms. I live and work in NE Pennslyvania and this product stood up to the past Polar Vortex that stayed over much of the US.

Rated 1 out of 5 by from Do not recommend! The lable states that some slush may appear at approximately 0*F. I had an extra jug of this product on my patio and at 0*F it was nearly frozen solid -- way more that just some slush. I winterized my new RV with this and now I'm worried about the plumbing system in my RV. I tried to contact the manufacturer. The label has a website address which came up as "not found" on my web search.

Rated 5 out of 5 by from Great Product. Good price. Works as expected. Use this in my travel trailer. Have had no issues with it. Cheaper then buying from Camper Store.
