What is a backflow prevention device and who needs it?
A. A backflow prevention device is a mechanical device located at the meter that prevents a reverse flow of water (backflow) into the distribution system in case of a pressure loss in the line. This prevents contaminants from flowing into the distribution system and spreading to other locations. Commercial customers are required to have a reduced pressure principle assembly (RP) installed immediately after their water meter to protect our water distribution system. RP’s provide the best protection for the public water system. Commercial utilities customers are required by City code to have their RP’s tested annually by a Certified Backflow Prevention (BFP) Tester. They may fax the backflow tester’s report to (386) 756-5370. Our residential utilities customers with reclaimed water have a double-check BFP on their potable water meter to prevent cross-connection with their reclaimed water irrigation system. Irrigation systems using potable water need a pressure vacuum breaker BFP before t
