Cholila Cover Backflow Insulated Cover (5°F) - 16x20, 7-Layer Winter Pipe Protection

Cholila Cover Backflow Insulated Cover for Winter Pipes

When cold weather arrives, outdoor backflow valves and sprinkler lines face the risk of freezing. The Cholila Cover Backflow Insulated Cover is designed to help keep key connection points warmer, offering a practical layer of protection that may reduce disruption to your outdoor irrigation setup.

Seven layers of protection for thermal performance

The design stacks seven materials to minimize heat loss and shield components from moisture. The outer shell uses 600D Oxford fabric with a water-repellent finish. Inside, two non-woven layers and two PP cotton layers add warmth, followed by a foil layer and a waterproof lining to enhance thermal efficiency.

• Outer layer: 600D Oxford fabric with water repellency
• Inner layers: two non-woven plus two PP cotton for insulation
• Aluminum foil layer: reflects heat back toward pipes
• Waterproof lining: guards against moisture

Size, fit, and clearance

The cover measures 16 by 20 inches on the outside. For a comfortable fit, measure your pipe size and reserve at least about 3 inches of extra space to account for thickness.

Protection features you can rely on

• Anti-wind seal: bottom uses Velcro to help reduce cold drafts
• Security options: two metal loops support cable ties or small locks
• Aluminum foil insulation: a high purity barrier that enhances freeze protection

Practical usage tips

Note: In areas with persistent freezing, avoid removing the return valve cover and opening the valve, as the pipe may become brittle under cold conditions. This cover is one layer of a winter protection plan.

Installation at a glance

Measure, fit, and secure: ensure the outer dimensions fit around the valve and that the cover seals well around the pipe. Use the Velcro bottom and the metal loops to keep the cover in place during wind or rain.
