Backflow Prevention​

Backflow is the undesirable reversal of the flow of water or mixtures of water and other undesirable substances from any source (such as used water, industrial fluids, gasses, or any substance other than the intended potable water) into the distribution pipes of the potable water system. Backflow occurs as a result of a “cross-connection” within the water system, which exists when there is any actual or potential connection between a potable water system and any other source or system through which it is possible to introduce into the potable system any used water or other substance.

The need for cross-connection control exists in all types of premises, whether industrial or residential. Backflow prevention devices help protect the public safety by preventing potable water contamination in such critical areas as municipal water systems, food processing plants, medical and dental water supplies, and many industrial applications. The Safe Drinking Water Act, signed into law in 1974, placed the responsibility of local governments and water authorities for drinking water protection. Backflow Prevention Assemblies can protect your drinking water and promote public health and safety.

Your backflow assembly should be tested annually to ensure the safety of your drinking water. A failed building inspection can cost you much more than the cost of getting a backflow installed properly and tested regularly. At Hamilton Plumbing Services we can provide you with a licensed technician to perform backflow assembly testing for your commercial building to ensure your inspections and certifications are up-to-date.
