Back flow prevention devices are necessary to prevent potable water from becoming contaminated. There are conventional products that help prevent back flow from contaminating a water supply. The simplest method of preventing backflow is an air gap that uses valves and gravity. When new devices need to be added to an existing plumbing system, it is often possible to retrofit the pieces to the old fixtures so that the entire system doesn't need to be replaced. This presents people with an economical method of staying up-to-date with changing building codes. Some municipalities require back flow prevention devices to be inspected regularly to reduce the possibility of water contamination.
