What is the purpose of a Backflow Prevention Device?

A backflow prevention device is designed to keep the public drinking water free from contamination. Contamination can occur anywhere a public and private water system connect (i.e. city main and your house). Contamination is any substance that has the potential to be introduced into the water system that may cause harm to the public. This could be fertiliser, house hold cleaners or other agents.
