Back flow preventors are those devices specifically designed to prevent the harmful effects of backflow and back-siphonage.

To understand better how a back flow preventor works, one must first understand the nature of back flow.

Back flow generally occurs when there is a sudden drop in water pressure from the main water supply to a home or business. When this water pressure drops, the flow of water basically reverses, meaning that contaminated water in a home or business will flow away from the home or business back into the main water supply, thus contaminating the potable water supply of the community.

Back flow preventors are basically backflow valve mechanisms that automatically shut down the flow of water when there is a drop in the water pressure, thus preventing water from reversing direction.  Some of the more reliable back flow devices are made by Ames and FEBCO, backflow preventers with a proven track record over the years.

The State of Texas requires annual backflow testing.  This requirement is directly related to the Clean Water Act of 1972, a federal initiative designed to protect all water supplies and systems in the United States.  This means that all cities and  communities in the state of Texas are required to maintain proper records and enforce this law.

Backflow testing companies are required to maintain licensing and backflow certification in the state of Texas and in all municipalities where they conduct their business.  This means not only being certified by the State of Texas but also being certified by each separate town and city where business is conducted, and every town and city is required to keep accurate and up-to-date records of all certified backflow testers and all annual testing that is done by every home and business owner.
