You may ask why I have to have a backflow device. Why do I have to test it?

Utah State law requires you to obtain a backflow preventer device and have it inspected annually if you have a lawn sprinkler system or any other potential hazard. Many types of backflow prevention systems also have test cocks so that they can be tested or examined to ensure they are functioning properly.

The purpose of a backflow preventer is to protect the public’s municipal water system from contaminants or pollutants by isolating sources of contaminants or pollutants within a customer’s internal water distribution system which could backflow or back-siphon into the city’s water system.

The water supplier is required by the EPA, State and local codes to have an active program to:

To eliminate and control cross-connections that exists between a customer’s potable water system and non-potable water systems; and to evaluate and reduce the following potential hazards to the suppliers’ potable water supply:

1. Health hazard: any actual or potential threat of contamination of a physical or toxic nature to the city’s water system or the consumer’s potable water system that would create or, in the judgment of the water supplier, may create a danger to health;

2. Plumbing hazard: any internal or plumbing type of cross-connection in a customer’s potable water system that may be either a pollutant or contamination-type hazard. The term “plumbing hazard” includes, but is not limited to, cross-connections to toilets, sinks, lavatories, wash trays, washing machines or lawn sprinkling systems. Plumbing-type cross-connections may be located in many types of structures, including homes, apartment houses, hotels and commercial and industrial establishments. An appropriate type of cross-connection control assembly, if permitted, must properly protect such a connection;

3. Pollution hazard: any actual or potential threat to the physical properties of the water system or to the quality of the water supplier’s or the consumer’s potable water system, but which would not constitute a health or system hazard, as defined;

4. System hazard: any actual or potential threat of severe damage to the physical properties of the city’s water system or the consumer’s potable water system or of a pollutant or contaminant that may have a negative effect on the quality of the potable water in the system;

5. Industrial fluids system hazard: any fluid or solution that may be chemically, biologically or otherwise contaminated or polluted in a form or concentration such as to constitute a health, water system, pollution or plumbing hazard if introduced into an approved water supply. This type of contamination includes but is not limited to polluted waters; all types of process waters and used waters; chemicals in fluid form; plating acids and alkalis; circulated cooling tower waters (open or closed) that may be chemically or biologically treated or stabilized with toxic substances; contaminated natural waters, such as from wells, springs, streams, rivers, harbors or irrigation canals; oils; gases; glycerin; caustic and acidic solutions; and all other solutions which may be used for industrial or fire-fighting purposes.

Your backflow device is an important part of this protection system.
