Master Craft Explains Backflow Certification

Posted by Brian Johnston on Wed, Jan 12, 2011

This is part three of three in the series of blog articles to explore why backflow prevention is important for us all, who has or should have a backflow preventer, and why certification of that device is needed.

Certification is needed!

Just like all working systems, they perform best when maintained and certified regularly. Backflow into a public water system can pollute or contaminate the water in that system and each water supplier has a responsibility to provide water that is usable and safe to drink under all foreseeable circumstances. Furthermore, consumers generally have absolute faith that water delivered to them through a public water system is always safe to drink. For these reasons, each water supplier must take reasonable precautions to protect its public water system against backflow.

Mechanical backflow preventers have internal seals, springs, and moving parts that are subject to fouling, wear, or fatigue. Also, mechanical backflow preventers and air gaps can be bypassed. Therefore, all backflow preventers have to be tested periodically to ensure that they are functioning properly. A visual check of air gaps is sufficient, but mechanical backflow preventers have to be tested with properly calibrated gauge equipment.

Responsibility: Consumer

The consumer has the responsibility of backflow prevention. It is at the consumer’s expense in most areas that they shall install, operate, test and maintain approved backflow prevention assemblies as directed by the authority having jurisdiction. Check your records and make sure your backflow preventer is certified! Remember to look for a plumber who is certified to complete your inspection, make the repairs, and notify the water authority of your compliance.

Master Craft Explores Backflow

Posted by Brian Johnston on Mon, Jan 10, 2011

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.backflow assemb dia resized 600

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
