This is part two of three in a series of articles to explore what the backflow preventer device does for us all, who has or should have one, and why certification is needed.
The public water utility companies send letters of certification reminder because they want to make sure your connection to the public water supply has a backflow preventer to prevent backflow.
So what is backflow?
Backflow is the reversal of flow of non potable water or other substances through a cross-connection and into the piping of a public water system or consumer's potable water system. There are two types of backflow…backpressure backflow and backsiphonage.
Both are types of backflow are undesirable and the best place to add prevention is in the connection to the water service. The backflow preventer is installed on the street side of that connection.
Now we know what we are trying to prevent, how many backflow preventers do you need?
Generally, this would include the water service connection to each dedicated fire protection system or irrigation piping system and the water service connection to each of the following types of premises:
- premises with an auxiliary or reclaimed water system
- industrial, medical, laboratory, marine or other facilities where objectionable substances are handled in a way that could cause pollution or contamination of the public water system
- premises exempt from the State Plumbing Code and premises where an internal backflow preventer required under the State Plumbing Code is not properly installed or maintained
- classified or restricted facilities
- tall buildings
