Irrigation Backflow Preventers Protect Your Drinking Water

GRU delivers safe, high-quality water to your home or business. Our Backflow Prevention program, which is required by the Florida Department of Environmental Protection (FDEP), protects the community’s water supply by preventing water from unknown sources from entering the distribution system. Irrigation Backflow Preventers (BFPs) are a crucial part of any irrigation system. BFPs prevent non-potable water from mixing with your drinking water. This is why state and local laws require property owners to test backflow preventers. A certified tester is required to submit proof of testing to GRU within 30 days of testing.

GRU sent me a notice to have my BFP tested. What do I do now? What could go wrong if I don’t have a BFP? What does a BFP do? Why do I need to test my BFPs? How often are BFPs required to be tested? Why do water customers have to pay to maintain and test their BFPs? Which type of BFP should I use for my in-ground lawn irrigation system? I have a well on my property, and I also have city water with a BFP on my side of the water meter. How can I get rid of the BFP? How and why do I winterize my BFP?
