In order to prevent this from happening, there are a number of different methods used. The simplest method and by far the most common one is to install an air gap, a vertical space between the inflow of fresh water and the outflow of dirty water. There are many different ways of achieving this, a prime example being the distance between the head of a sink faucet and the highest level of the sink.

But, sometimes the source of potable water and drain are too close together and there’s simply no room for an air gap. Whenever this is the case, we here at Affordable Service will always turn to the backflow preventer as the best choice for preventing backflow. A backflow preventer is a device that connects right into your plumbing system and keeps contaminated water from entering back into the pipes. There are many different models, each one suited for different environments and flow volumes.

DIYers beware: these are complicated devices that require periodic inspection by professionals.
