Backflow Preventers

What is a Backflow Preventer, why does my building need one?

  • A Backflow Preventer is a device that prevents the undesirable reversal of flow of water; caused by the sudden or unexpected change in water pressure; from your building into the City’s potable (drinking) water supply.
  • Without such a Backflow Preventer, contaminated water, chemicals or disease could potentially enter the City’s domestic water supply from your building!

What should I do now?

  • As the letter states, you have thirty (30) days to “initiate the process”. Contact A & A Plumbing Systems. We will have our Licensed Engineer draw up a set of approved plans for the installation of the necessary Backflow Preventer device(s). We will then work with you through the installation, testing and sign off.

I have my engineer working on this already…

  • Upon receiving the plans approved by the NYC DEP from your engineer,  A & A Plumbing  will provide you with a free estimate to install, test and sign off on your device(s).

What else do I need to know?

  • If you just completed a new installation, or already have a device previously installed, the New York City requires annual testing of the Backflow Prevention device(s).  A & A is a licensed Backflow Preventer testing company.
