Effortless setup
No tools. No tape. Designed for immediate, foolproof deployment in the field.
Slide the blanket over the backflow preventer. The continuous polyfill core molds to the valve body without snagging on test cocks.
Press the industrial-grade velcro seams together along the bottom edge to form a zero-gap thermal seal against the ground or slab.
Thread a standard padlock through the brass grommets to secure against weather and theft. Installation is complete.
Material Specifications
22oz polyvinyl
Our UV & fire-retardant polyvinyl exterior is exactly twice as thick as the standard 11oz. material used by our competitors, guaranteeing years of extreme outdoor protection.
10 hrs at 0°F
Rigorously tested to maintain water flow in static lines for up to 10 continuous hours in zero-degree weather.
All insulation is cut in whole, continuous pieces rather than scraps. This minimizes internal gaps that commonly cause unexpected freeze-ups.
We use heavy-duty, double-stitched UV-resistant nylon sewing thread to ensure the structural integrity survives years of intense sun exposure.
Every seam is double-sewn to completely seal out weather elements. Side seams on heavy-duty models feature additional metal rivets to prevent splitting.
Secure your blanket with locks using pre-installed grommets. We also offer velcro seams for specialized devices requiring partially open tops or sides.
The Cost of Doing Nothing
A single hard freeze can destroy an unprotected backflow valve in hours. The resulting damage costs exponentially more than preventative insulation.
Without protection
Cracked outer body: The bronze or iron shell splits from ice pressure.
Broken internal parts: Internal seals, check valves, and relief mechanisms warp or break.
Sudden flooding or leaks: Thawing ice results in massive spraying or hidden underground leaks.
System failure: Your irrigation or water line stops working properly.
Expensive repair bills: Replacing a damaged assembly requires professional parts and labor.

Best Choice BFB is a premier American manufacturer of high-performance, insulated canvas covers engineered specifically to safeguard backflow prevention assemblies from severe freeze conditions and costly environmental damage.
The company was founded in Vallejo, California, located 45 miles northeast of San Francisco. Originally established under the name World Wide Canvas Products, the business began with a focused municipal objective: solving critical freeze-vulnerability challenges for local water infrastructure.
Our flagship Backflow Blanket was designed, tested, and deployed directly in partnership with the City of Vallejo Water Department.
Following successful municipal implementation, Ewing Irrigation became our first commercial distribution partner. As municipal utilities, commercial contractors, and landscape professionals observed the durability and field effectiveness of our covers across city installations, national demand expanded rapidly. To reflect our specialized product focus and market leadership, the company formally rebranded to Best Choice BFB.
Still proudly independently owned and operated, Best Choice BFB remains grounded in the foundational principles that built our reputation: exceptional customer service, uncompromising manufacturing quality, and dependable protection for vital water systems.
We provide the documentation, tier-pricing, and terms required to smoothly integrate with your city's purchasing department.
We accept Net-30 POs from recognized municipalities, water districts, and commercial contractors.
Tiered municipal pricing available for city-wide winterization rollouts and bulk fleet orders.
