A backflow preventer is a device used to protect against the reverse flow of water, known as backflow, in a city’s water system.  If the backflow is left unchecked, contaminated water can flow from a home or building back into the potable water supply…..

And that just cannot happen!

Here’s how it all works.  When you turn on the water from a tap in your home, pressure forces water from the potable water supply to your home and out the tap.  That water pressure is constant and as long as it remains constant everything works properly and you, the home owner, can take your shower, wash your dishes and rinse off your car without a care.  However, if for some reason water pressure diminishes, it is quite possible for the water pressure to actually reverse, which in turn means the water flow will reverse, and that’s when major problems arise.

But not if a backflow preventer valve is used, and rest assured that most cities and towns in America now require the use of backflow preventers, otherwise known as backflow valves or backflow prevention devices.

Companies like Febco, Watts and Wilkins make a variety of backflow preventers, double check valves, pressure vacuum breakers and rpz valves, and any licensed backflow testing company like City Backflow Testing will be able to not only conduct an affordable backflow testing but also install backflow devices for your home or business.

In the United States the Environmental Protection Agency is the regulatory agency in charge of backflow testing, and it holds local water suppliers responsible for the integrity of the water supply.  Most states and most towns require annual backflow testing.  Texas is one of those states where annual backflow testing is required, which means that Arlington backflow testing, Grapevine backflow testing, Richland Hills backflow testing, Southlake backflow testing, all cities in Texas conduct and require certified backflow testing.

Backflow prevention devices come in many shapes, sizes and names including air gaps, atmospheric vacuum breakers, check valves, double check valves, pressure vacuum breakers, reduced pressure zone devices and rpz valves.  Each performs a specific function, and when installed by a certified backflow testing company, like City Backflow Testing, each will guarantee that the potable water supply in your city will remain contaminant-free.
