Cholila Cover Backflow Insulated Cover – 30 x 24 in, 7-Layer Fabric with Aluminum Foil

Cholila Cover Backflow Insulated Cover — Winter-Ready Protection

Protect outdoor backflow preventers from winter chill with the Cholila Cover Backflow Insulated Cover. Built as a seven-layer system, this cover combines tough, weather-resistant materials with thoughtful insulation to help slow heat loss and shield critical piping components from freezing temperatures. While this is not a guarantee against all weather scenarios, it offers a practical option for seasonal protection.

What makes it fit for cold weather

The exterior is a durable 600D Oxford fabric with a water-repellent finish, paired with a waterproof inner lining. Inside, two layers of non-woven fabric and two layers of PP cotton work with a dedicated aluminum foil layer to reflect heat back toward the pipe. The result is a single, cohesive layer that helps maintain warmth around the backflow valve.

• Outer dimension of 30" W x 24" H, designed to accommodate typical backflow setups
• 7-layer construction includes aluminum foil for enhanced thermal insulation
• Water-repellent outer shell and waterproof inner lining resist moisture and wind-driven moisture
• Two layers of PP cotton plus non-woven layers create a soft yet durable barrier

Key benefits and usage tips

Use this cover before the coldest days arrive to reduce exposure of the valve to frost. The bottom is secured with Velcro to seal out drafts, and two metal loops provide options for securing with cable ties or a small lock in exposed areas.

• Helps minimize heat loss around backflow components during freezing conditions
• Secures easily with Velcro; also lockable for added security in shared spaces
• Simple, tool-free installation and removal for seasonal use

Important notes

Measure your pipe size and allow at least 3 inches of clearance, as the stated 30" x 24" refers to the outer cover. In very low temperatures, avoid opening the valve to prevent added stress on pipes, which could lead to costly repairs.

With practical materials and a ready-to-use design, the Cholila Cover Backflow Insulated Cover offers a sensible option for winter protection—one that sits as part of a broader seasonal prep routine rather than a guaranteed fix.
