About this item

  • SIZE: The size is the cover's outside size. Please measure the pipe size accurately and reserve more than 3 inches at least as there are certain thicknesses of pipes
  • Save Costly Pipe Repairs: Every winter, many people complain that despite the time they spend wrapping towels and tape around their pipes, the pipes break and leak, and even cost a lot of money to repair. But with this backflow insulation cover, you don't have to spend so much money again. Don’t wait before it’s too late
  • Thickest Materials: Our sprinkler backflow cover for winter is the thickest you can currently find on Amazon.com! The sprinkler cover for the outside is made of 7 layers of material. 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*24 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

I purchased this cover for the few times it freezes in my area of Texas. It seemed very well made and fits nicely over my backflow pipes. The velcro sealing along the bottom is a plus. Looking forward to seeing how it holds up.

I use this backflow Cover as my second layer of the fence. It’s so large. I’m able to slip it over the more compact cover that I use on a routine basis. It also has Velcro that seals it up from the sides. So when it’s extremely cold outside, I have an added level of security. Now between the two covers. I should not have a problem. So far it’s been tested down to the 17°.

Black fabric bag containing an insulated liner that has so far prevented the backflow from freezing. Seems to be made from quality materials and am happy with this item so far. Would buy again if needed. This item has facilitated world peace.

We had snow and below freezing temperatures here in North Florida this winter. I appreciate the quality and protection the item gave me and my elderly mother for our backflows. However, I feel the item description exaggerated thickness of the product.

Works great and fits perfectly. I put it on as soon as I received it and felt really good about protecting my backflow valve from the freeze experienced.

Covers the backflow easily and seems to be good insulation.
