02 — THE VULNERABILITY

Unprotected Risk vs. Guaranteed Defense

Every winter, unprotected backflow prevention assemblies freeze, crack, and fail—costing property owners thousands of dollars in emergency repairs, plumbing replacements, and municipal fines. Drag the slider below to see the difference.

Protected Solution

The Vulnerability: $3,000+ in Damage

Exposed metal backflow assemblies have standing water inside them at all times. When sub-freezing temperatures arrive, this water freezes and expands with immense force, resulting in structural failure.

Cracked Copper & Brass Bodies

Freezing water expands, splitting thick metal pipes and internal valves instantly.

Emergency Plumber Fees

Emergency response rates double or triple during winter freeze warnings.

Massive Flooding & Water Fines

Ruptured lines leak thousands of gallons, leading to property damage and municipal fines.

Estimated Repair Bill$2,200 – $6,450+
New Assembly:$1,500 - $4,500Emergency Labor:$500 - $1,200City Permit & Re-Test:$200 - $750

The Solution: Contractor-Grade Protection

Installing our custom insulated Backflow Blanket creates a heavy-duty thermal envelope. It seals in ground heat and prevents temperatures from dropping to critical freezing thresholds.

R-11 to R-30 Thermal Core

Thick, dense insulation maintains pipe temperature for up to 10 hours at 0°F.

Weatherproof 22oz PVC Shell

Heavyweight, UV-resistant fabric prevents windchill penetration and splitting.

Anti-Theft Brass Grommets

Pre-installed lockable grommets allow you to secure the blanket against copper thieves.
