The outer layer is 600D Oxford Fabric with a water-repellent effect, the inner layer is two layers of non-woven fabric, two layers of PP cotton with thermal insulation, a layer of aluminum foil with a thermal insulation effect, and a layer of waterproof lining. They help keep your pipes warm and from bursting during freeze
- Cover Size: Our backflow valve cover insulated is 24*30 inches. What we provide is the outer dimension of the product, and the product itself has a certain thickness. So please measure your pipe size and reserve about 3 inches or more of extra space before purchase
- Insulation Aluminum Foil: Aluminum foil is made of electrolytic aluminum or aluminum alloy sheet with a purity of 99.3% to 99.9%. Aluminum foil is a recognized material that isolates packaging items from the outside world, whether it is water vapor or air, etc, which greatly enhances the antifreeze performance of the backflow insulation cover
- Anti-wind and Anti-theft: The bottom of the backflow cover is Velcro, which keeps the cover sealed closed to prevent cold wind from entering. There are also two metal loops on the Velcro, you can use our cable ties or use your chain or small lock to fasten it to prevent it from being easily stolen by others
- Notice: If your environment is still at low temperature, please try not to remove the return valve cover and open the valve. Because the water pipe may become brittle under the influence of low temperature, if the valve is opened at this time and the water pipe bears a certain pressure, it may burst, resulting in huge maintenance costs
