Backflow is when the water travels in the reverse direction. While building codes and mandates do most of the work to prevent backflow issues, there might be additional services that you might want to employ if you are a home or business owner who wants to prevent any backflow issues.
Backflow is caused typically due to a back siphonage or back pressure. With back siphonage, the water pressure is being lowered below that of the system. This typically occurs when the water supply is drained down or interrupted. With back pressure, it’s when higher pressure is in the system than its supply. Typically this stems from the system pressure increases, causing the backflow.
Benefits of A Backflow Preventer
A backflow preventer is a device that is installed into the water pipes that enable the water to flow in one direction — but would never permit the water to flow in the opposite direction, preventing backflow issues. Its main job is to prevent drinking water from being contaminated, or toilet water potentially contaminating drinking sources. Depending on the severity of the contamination, drinking water can be exposed to potable water, or Category 1. As you increase in categories, the more severe the contaminated water is, with Category 5 water causing serious health risks to your family. It might be difficult to categorize the contaminated water for the uninitiated. This is where the role of the backflow preventer comes into play — it prevents the issue from occurring altogether.
A backflow prevention system creates a one-way gate that allows water from public supply to flow into your home but stops water if and when it ever tries to flow back to the main water source.
Will a backflow prevention system help my home? Most residents can be helped with a backflow preventer, with some states or communities requiring it at the water meter.

The potential for backflow requires a solution before your water is affected. One of the best methods to prevent backflow is to place an air gap. These are open spaces between a fixture in your main plumbing system, with the air gap placed in a location where water collects. Most air gaps are manufactured between your faucet and the sink rim.
A backflow preventer is also installed by a licensed plumber in lieu of the air gap. The device is installed adjacent to the building’s main shut off valve. Contaminates will not be able to flow back into the city’s supply.
Keep in mind that if you currently have a backflow preventer, it will require regular maintenance, preferably yearly. Older homes especially need to be serviced on a regular basis, since the backflow device can become worn out and compromised after years of use.
