5-Layer Backflow Preventer Cover for Winter,-4°F,20" H x 16" W

Features

• Heavy-Duty Waterproof 600D Oxford + 2 Foil Layers: Built with waterproof 600D Oxford fabric, two layers of 1600# cotton, and two layers of aluminum foil. The foil reflects radiant cold back toward the valve, while the outer shell blocks cold air, rain, and snow — and resists UV fading and tearing.
• Bonus Straps for a Secure, Windproof Fit: Each insulated backflow cover includes extra tie-down straps to keep it firmly in place during storms — no more blown-off covers or cold air gaps. Your equipment stays protected all winter.
• Size: 20"H x 16"W – For Standard Backflow Preventers & Sprinkler Valves: Fits most standard backflow preventers, sprinkler valves, and smaller water well pumps. The slip-on design installs easily — no need to remove equipment. For the best fit, measure your equipment and add 3 inches to both width and height, then confirm it fits within 20"H x 16"W.
• Bonus: Stainless Steel Grommets & Superior Single-Opening Seal: The stainless steel grommets resist rust and let you lock the cover with a chain for added security. The single-opening design creates a tighter seal than open-sided covers, keeping cold air out. Works with backflow preventers, sprinkler systems, water well pumps, and other related equipment. Reusable season after season.
