The City of Highland Village, Texas, has a rather detailed explanation of their backflow prevention program on their website.  The most important portion of that program is mentioned below:

“Backflow prevention assemblies shall be installed in accordance with the City’s Plumbing Code and City ordinances. The assembly installer shall obtain the required permits prior to installation and shall have the assembly inspected by a certified cross connection inspector and as required by the Plumbing Code and City ordinances.”

Now let’s take a closer look at the Highland Village Backflow Prevention Program.

Circumstances requiring backflow prevention

The City of Highland Village lists in considerable detail the situations which require backflow protection.  Follow that link to read them all.  What we will do in this article is give you an overview of backflow and how it is prevented in Highland Village.

The water that you use at home or in your business, in Highland Village, arrives at your location by means of water pressure.  Pressure is supplied at the City’s water source, and that pressure pushes potable water to all homes and businesses in Highland Village.  That is how the system is supposed to work, and that is how it does work 99% of the time.  But . . .

There are times when the water pressure drops (busted water main; too many fire hydrants opened to fight a fire), and when those situations happen, the water pressure drops significantly, which in fact means there is more water pressure at the home or business end of the water system, meaning water will reverse flow, or backflow, and return to the original source.  In other words, contaminated water will flow back to the potable water source, and that simply cannot be allowed to happen.

Thus we have backflow preventers.

Backflow preventers, or backflow devices, are mechanisms which do not allow water to flow in the opposite direction. They are usually valves which will only allow flow to go one way, and they are installed at every cross-connection in your water system.  A cross connection is defined below:

Any physical connection or arrangement between two otherwise separate piping systems, one of which contains potable water and the other either water of unknown or questionable safety or steam, gas or chemical, whereby there exists the possibility for flow from one system to the other, with the direction offlow depending on the pressure differential between the two systems. – UPC 2006
