Who can install the device, who tests and certifies the device and what are the costs?
The device must be installed by a licensed plumber and tested annually by a state certified backflow technician. The cost of the device, its installation, and the annual testing of the device varies, and will depend on what must be done to install the device and who tests the device. Information on who installs and tests the device can be obtained from a phone book or online phone directory by looking under “Backflow Prevention Products and Services.” The device is installed at the owner’s expense. The property owner is encouraged to shop around and compare prices.
