What Is Backflow—and Why Should You Care?
Backflow occurs when water flows in the wrong direction in your plumbing system, pulling contaminants like fertilizers, industrial chemicals, or wastewater into your clean, potable water supply. This can happen due to changes in water pressure from events like a burst pipe or firefighting activities.
That’s why local codes require functioning backflow prevention devices, especially for commercial properties and irrigation systems.
A Properly Functioning Backflow Prevention Device Protects Against:
- Industrial fluids
- Gasses
- Used water
- Pesticides
- Other hazardous substances
Don’t take chances with your family’s or customers’ health.
Signs You May Need Backflow Repair or Replacement
Not sure if you have an issue? Here are some common warning signs:
- Water tastes or smells odd
- Discolored or cloudy water
- A recent drop in water pressure
- Your annual backflow test failed
- You've had recent plumbing issues or flooding
If you notice any of these symptoms, don’t wait. Backflow can lead to serious contamination fast.
