- Apr 17
- 3 min read
Clean water should never be a question.
Backflow prevention systems are designed to protect your home or business from contaminated water flowing back into your clean supply. But like any mechanical system, they require regular testing to ensure they’re working properly.
At Filan & Conner, we provide backflow testing and certification services throughout South Jersey, helping homeowners and businesses stay compliant, protected, and up to code.

What Is Backflow and Why Does It Matter?
Backflow occurs when water reverses direction in your plumbing system, potentially allowing contaminants like chemicals, bacteria, or waste to enter your clean water supply.
This can happen due to:
Sudden drops in water pressure
Pipe breaks or system failures
Heavy water usage from firefighting or construction
According to the EPA, backflow events can introduce hazardous substances into drinking water systems, posing serious health risks if not properly prevented.
👉 This is why backflow prevention devices and annual testing are required in many municipalities.
Why Backflow Testing Is Required in New Jersey
In New Jersey, many properties are required to have backflow prevention devices installed and tested annually, especially:
Commercial properties
Irrigation systems
Multi-family homes
Properties with fire suppression systems
Local towns across South Jersey, including Cherry Hill, Marlton, Voorhees, Mount Laurel, and Haddonfield, enforce backflow compliance to protect public water systems.
👉 Failing to test your device can lead to:
Fines or penalties
Failed inspections
Risk to your water supply
How Backflow Testing Works
Backflow testing is a straightforward but critical process.
Our certified technicians:
Inspect the backflow preventer for wear or damage
Test pressure levels and valve operation
Verify that water is flowing in the correct direction
Ensure the device meets local code requirements
Once testing is complete, we provide official certification documentation required by your municipality.
👉 Most tests take less than an hour but provide long-term protection.
Signs Your Backflow Device May Need Attention
Backflow issues are not always obvious, but there are warning signs:
Discolored or foul-smelling water
Sudden drops in water pressure
Visible leaks around the backflow preventer
Unusual taste in drinking water
If you notice any of these, it’s important to act quickly.
