What Happens If Your Backflow Preventer Is Stolen or Hit by a Car?
Backflow preventers installed near parking lots, drive lanes, sidewalks, irrigation systems, and commercial properties are sometimes damaged by vehicles or stolen for scrap metal. When this happens, the plumbing system may leak heavily, lose pressure, or become non-compliant with local water utility requirements.
Fast repairs are important because damaged or missing backflow devices may leave the water system unprotected and could result in water waste or service interruptions.
Why Backflow Preventers Are Sometimes Stolen
Many backflow preventers are made from brass or other metals that may attract scrap theft.
Assemblies installed outdoors near roads, parking lots, commercial plazas, HOAs, or irrigation systems are often more vulnerable because they are easily accessible.
Common Theft Targets
- Irrigation backflow preventers
- Commercial property assemblies
- HOA irrigation systems
- Backflows near parking lots or sidewalks
- Exposed brass assemblies without cages
What Happens When a Backflow Preventer Is Damaged?
Vehicle impacts or vandalism can crack pipes, break valves, or completely destroy the assembly.
| Damage Type | Possible Result |
|---|---|
| Vehicle collision | Broken piping or destroyed assembly |
| Theft removal | Severe water leaking or flooding |
| Corrosion after impact | Long-term reliability problems |
| Valve or fitting damage | Failed inspections or pressure loss |
What to Do if Your Backflow Preventer Is Missing or Damaged
If the assembly is leaking heavily or completely missing:
- Locate the irrigation or water shut-off valve if safe to do so.
- Keep people away from damaged piping or flooding areas.
- Call a licensed plumbing professional for emergency service.
- Document visible damage for insurance or property records if needed.
If you are uncomfortable shutting off the water system, call Amy’s Plumbing immediately.

How Protective Cages Help Prevent Theft
Protective backflow cages help reduce theft and vandalism risks by making assemblies harder to access and remove.
Theft Deterrence
Metal cages help discourage quick removal of exposed brass assemblies.
Added Security
Lockable cages may help limit unauthorized access.
Commercial Protection
HOAs and commercial properties commonly use cages for exposed assemblies.
How Concrete Bollards Help Protect Backflow Devices
Backflow preventers installed near vehicle traffic are often vulnerable to accidental impacts.
Concrete bollards or protective posts may help shield assemblies from:
- Parking lot accidents
- Delivery vehicle impacts
- Lawn maintenance equipment
- Backing vehicles
- Commercial traffic areas
Protective barriers are especially helpful for assemblies located near storefronts, HOA entrances, parking spaces, and drive lanes.
