Information:

Our covers are designed to protect backflow devices during temporary freezing conditions, such as cold snaps and overnight freezes. They are primarily intended for frost protection.

In climates with prolonged or extreme freezing temperatures, we recommend using a solid enclosure with a heating element for more reliable protection. 

The R-19 insulation rating applies to the walls of a properly installed cover. Due to the open bottom design, some conductive heat loss is expected. However, the cover functions as a weather-resistant barrier that delays the onset of freezing conditions.

Under controlled conditions—32°F ambient temperature, no water flow, and no wind—protection duration is approximately 18 hours. At 15°F, expected protection time is approximately 10 hours, consistent with industry standards. Active water flow during freezing conditions will extend protection time.

Blankets and covers are shipped compressed. Full material expansion occurs over approximately two weeks, with any creasing or wrinkling naturally dissipating.
 

Our products are manufactured in California. Proudly made in the United States of America. Crafted with quality materials that will hold up under extreme cold, rain, snow, wind and summer heat.
