Back Flow Prevention and Water Safety
Back Flow preventers are required in the savannah area on all commercial building and on any residential home that has a sprinkler. A back flow preventer is a device that keeps the city water supply safe from irrigation systems or other systems from back feeding unprotected open water from getting back into your drinking supply. In Savannah, backflow prevention device is used to protect water supplies from contamination or pollution due to back.
Low Country water supply is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several hoses are opened). Reduced pressure in the pipe may allow contaminated from soil, from storage, or from other sources to be drawn up into the system.
