Backflow Freeze & Theft Protection
Backflow assemblies sit exposed — vulnerable to hard freezes, vandalism, and copper theft. We supply and install insulated covers, freeze bags, and security cages to protect your investment.
Because backflow preventers are installed above ground, they take the brunt of the weather and are an easy target for vandalism and metal theft. A single hard freeze can crack a brass body and cause an expensive emergency repair — and a flooded landscape — overnight.
All Pro Backflow protects your assembly with insulated freeze covers, freeze bags, and steel security cages, sized and installed to fit your device. It is inexpensive insurance against the most common (and most avoidable) backflow failures.
Freeze Protection
Insulated covers and freeze bags rated to keep assemblies from cracking in a hard freeze.
Theft & Vandalism Deterrence
Heavy-gauge steel security cages make your assembly far harder to tamper with or steal.
Sized to Fit
Standard and custom sizes for any make and model — measured and installed correctly.
Insulated covers & freeze bags
Our insulated backflow covers are crafted from durable vinyl that resists water, mildew, fire, and UV, and double-stitched to hold up season after season. They blend into the landscape while keeping the assembly above freezing through Northern California's coldest nights.
Need just the bag? Our sister company, The Backflow Depot, manufactures USA-made freeze bags in over 50 sizes and ships them same-day — and when you want them measured and installed, our crews handle that too.

Security cages & enclosures
A broken or stolen valve means an emergency repair, a compliance violation, and potential water damage. Our welded steel security cages and lockable enclosures deter theft and vandalism, protecting both your assembly and the water supply behind it.
