Our potable or “clean” water flows under water pressure through water lines to homes and businesses. Backflow is the reverse flow of what we call dirty water through these typically clean water lines. Dirty water is typically contaminated with feces, pesticides, chemicals, fertilizer and other hazardous materials, and can create a serious health hazard. Backflow can occur at cross-connections between potable and non-potable water in any residential, commercial or industrial water system.


Most municipalities will require the installation of a backflow prevention device at each cross-connection point found within the plumbing systems of apartments, condominiums, food establishments, and in most of our public and commercial areas. The type of backflow preventer needed will be consistent with the amount of hazard present on the premises.


A backflow prevention device typically consists of a pair of mechanical check values that prevent a home or businesses dirty water from flowing back into the systems clean water supply in the event of an unexpected or drastic change in water pressure thus ensuring the safety of the clean water. If properly installed and maintained, a backflow preventer will keep drinking water safe and free of contaminants like feces, pesticides, chemicals, fertilizer and other hazardous materials.


Backflow valves must be inspected annually to ensure that they are operating properly so your property can be kept in compliance with the local code. Your fresh water supply is at risk of being interrupted and your business may be fined if backflow testing isn't completed in time.
