Backflow testing for JEA customers in Jacksonville
Updated · Editorial team; not yet technically reviewed
Short answer
JEA requires residential backflow preventers to be tested at least once every two years by a JEA Qualified Vendor, at the customer's expense. Homes irrigating with reclaimed water must have a backflow preventer, and residential dual check devices, where allowed, must be replaced every five years.
What's different in Jacksonville
Customers are responsible for testing required backflow preventers at their expense, by JEA Qualified Vendors, at least once every two years for residential premises. [1]
JEA customers who irrigate with reclaimed water must have a backflow preventer to protect the drinking water supply, and JEA arranges periodic testing of these residential devices as state rules require. [1]
Residential dual check devices are allowed with a signed agreement that no cross-connection exists between reclaimed and potable systems, and must be replaced every five years. [1]
Reclaimed water changes the rules
Purple pipes and purple-capped sprinkler valves mean reclaimed water: treated wastewater for irrigation only. Any link between that system and household plumbing would put it in your tap water, which is why JEA requires backflow protection and a written promise of no cross-connection before allowing a dual check.
What never to do
- Never connect a hose or pipe between a reclaimed spigot and a potable one.
- Don't remove or bypass a backflow preventer to raise sprinkler pressure.
- Don't hire a tester who isn't on JEA's qualified vendor list; the test won't count.
