A: Yes, all exterior backflow devices are required to be in a protective, above-ground box.
Q: How often does my backflow device need to be tested?
A: Upon installation or reinstallation, after any maintenance, and annually thereafter. If you remove your backflow device for the winter, it must be retested after it is reinstalled.
Q: What do I do with the test results?
A: Residents should keep a copy for themselves, and ensure that the backflow technician contacts BSI Online and have the test data placed in their online system.
After your information is in this database, residents will be assigned their customer confirmation number (CCN). They can use this number to ensure their device is listed on the BSI website.
Q: Where do I install the backflow preventer?
A: Devices must be installed within ten (10) feet of the water meter. New lawn irrigation systems installed after July 1, 2009 must be on a separate meter. Some exceptions may be allowed for fire suppression systems or where installation is not feasible due to facility design. ALL exceptions will be reviewed by Town officials to make FINAL determination.
