Why is a backflow prevention device important? A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. A backflow device is also known RPZ valve (Reduced Pressure Zone)
But the question you might have is what is backflow? and how does it happen?
This is something you should know if you’re a Granada Hills homeowner or business owner. For example, backflow can happen when there is a fractured part in your main water line or when a nearby fire hydrant is being used. During these events; this lowers the pressure. Water is no longer being pushed towards your home and will flow backwards to the city lines.
So what does the water contaminate with? well, my friend, your water can get contaminated with the following:

  • Soap that has been used from your showers, sinks, and dishwashers


  • Human waste (1’s & 2’s)


  • Chlorine from pools and jacuzzis 


  • fertilizers and pesticides 


And that’s when the backflow prevention flow system comes into play.
