What is a backflow prevention device and do I really need one in my home?
Backflow or back siphonage happens when water flows backward through your water supply system. When that water is accidentally mixed with chemicals such as pesticides or bacteria it can be very dangerous. The biggest danger is from your garden hose. If your water supply experiences a drop in pressure when the hose is submerged in a bucket or a spray attachment is being used, any chemical in the hose, bucket or spray attachment can be sucked into your home’s plumbing, contaminating the entire system. A simple backflow device can prevent this.
