Common Causes of Backflow and How to Prevent Them
Home /
Backflow is a plumbing issue that can have serious consequences, including contamination of your drinking water. Knowing the common causes of backflow and how to prevent them is essential for keeping your home safe. As your trusted company for backflow installation in Anna Maria, FL, Accurate Backflow and Plumbing understands how backflows start as well as the many ways they can be prevented.
Cross-Connections
One of the most common causes found during backflow testing is cross-connection, which occurs when potable water lines connect to non-potable sources, such as irrigation systems or fire sprinklers. If there’s a drop in water pressure, contaminants can flow back into your clean water supply. To prevent this, ensure that cross-connections are properly managed by installing backflow prevention devices, such as air gaps or vacuum breakers.
Backpressure
Backpressure happens when the pressure in your plumbing system exceeds the pressure in the public water supply. This can occur if you have a high-pressure system, like a boiler or a pump, that forces water back into the main line. To avoid backpressure-related backflow, it’s crucial to install a backflow preventer that’s specifically designed for high-pressure systems. Regular maintenance and backflow prevention device testing are key to ensuring they function properly.
Backsiphonage
Backsiphonage occurs when there’s a sudden drop in water pressure, such as during a firefighting operation or a water main break. This drop can create a vacuum that sucks contaminants back into your clean water lines. Installing a backflow preventer, like a double check valve or a reduced pressure zone (RPZ) assembly, as well as having regular backflow device testing, can effectively stop backsiphonage from occurring.
