What is water backflow?
Backflow is the flow of water from a building’s plumbing back into the public water system. This reversal of flow can be caused by drop in water pressure in the public system (such as from a water main break or hydrant usage) or an increase of pressure from within the building. This backflow of water may carry some contaminates from cross connections within the building back into the public system.
What is a water cross connection?
A connection between drinking water pipes and any source of potential contamination is a cross connection. When the water pressure changes from internal usage or water system fluctuations, contaminated water may back flow into your plumbing from unprotected cross connections. Common household cross connections are garden hoses left in a bucket of cleaning chemicals or in a pool and attachments to hoses used to apply lawn chemicals.
What is a water backflow preventer?
Backflow preventers protect the safety of the public water system by physically preventing the backflow of water and any potential contaminants from the consumer’s plumbing to the public system. The devices are installed by the consumer on their plumbing after the water meter.
Where are water backflow preventers required?
Backflow preventers are required by State law (Ohio Administrative Code 3745-95) and the Ohio Plumbing Code (chapter 608) to be installed where there is a potential health or contamination threat within the consumer’s plumbing system. Most commercial buildings and residential properties with in-ground irrigation system require a backflow prevention device. Further information can be found in the City’s Cross Connection Control Policy on the Water Division’s main web page (click on "Water" under "Services" to access this information).
What testing is required if I have a backflow preventer?
To ensure the device is working properly, the consumer is required to have annual testing done by a State certified backflow tester. Reports of this annual testing must be maintained by the consumer and forwarded to the Westerville Division of Water. Report forms are available on the Water Division's main web page (click on "Water" under "Services" to access this information).
