Remember, backflow prevention devices must be installed on all connections to the city water distribution system. The degree of hazard the service connection poses to the public water supply will determine what type of device will be required. If the service connection poses a potential risk of contaminating the water supply a testable backflow device is required and the device must be tested annually by a New York State Certified Tester. All test reports must be submitted to the Jamestown BPU Water Engineering Department upon completion of the test. Below is a link for a list of NY State Certified Testers in Chautauqua County as well as a link for the Test report - form DOH-1013.
Are you not sure if there is a backflow preventer in your facility? Here are some clues to help you figure it out:
- The backflow preventer that is of primary concern to the Jamestown BPU is the one located next to the water meter on the building side for each water service that connects your facility to the city water distribution main.
- Below are two examples of what the backflow preventer may look like (it varies per device manufacturer).
On the left is an image of a DCV (Double Check Valve) backflow preventer
On the right is a RPZ (Reduced Pressure Zone) backflow device.
- Look for the name of the manufacturer on the device. For a list of approved backflow prevention device manufacturers, you may look on the NYS Department of Health website
