Backflow Prevention
A backflow preventer is a one-way valve that stops water from your irrigation system or building lines from flowing backward into the drinking water supply, and most assemblies must be tested once a year. If a letter from JEA or your county utility says a test is due, this is the service that handles it — the test, any repairs, and the paperwork, filed for you.

Signs it's time to schedule
A letter from the utility says your backflow test is due
The most common way homeowners meet their backflow preventer. It means your property has a registered assembly and its annual test date has arrived — routine, and easy to handle.
Water leaking or spraying from the assembly near your sprinkler valves
A brass assembly relieving pressure or dripping steadily usually means an internal check or relief valve has worn out. A rebuild often fixes it without full replacement.
You are opening a business and the utility requires an assembly
Many commercial water services on the First Coast must have a tested backflow preventer. We install, test, and file so it is one less item on your list.
When does it make sense?
Book the test when the utility letter arrives — it carries a due date, but with a reasonable window, so simply pick a convenient day inside it. Utilities do follow up on ignored notices and can eventually interrupt service, which is why early scheduling is the calm move. Spring irrigation startup is another natural moment: if the sprinklers are getting their seasonal once-over, testing the assembly in the same visit saves a trip.
The Jacksonville angle
Irrigation is a way of life on the First Coast — St. Augustine grass from Mandarin to Nocatee runs on sprinklers most of the year, and every one of those systems connects to drinking water through a backflow assembly. JEA in Duval County, the Clay County Utility Authority, and the St. Johns County Utility Department each run annual testing programs. Out at Jacksonville Beach, Atlantic Beach, and Fernandina, salt air is harder on the brass assemblies, so coastal units tend to need rebuilds a little sooner.
How we handle it
- 01
Send us the letter
A photo of the utility notice — or just the assembly by your sprinkler valves — tells us the type and where the report needs to go.
- 02
We test on your schedule
The test is a short visit with a calibrated gauge, and you usually do not need to be home for an exterior assembly.
- 03
Pass or repair, paperwork handled
A pass gets filed with your utility, copy to you. A fail gets an upfront quote for rebuild or replacement, retest included.
- 04
A reminder next year
We note your test date and reach out when the next one approaches, so the annual letter never turns into a scramble.

FAQ
Backflow Prevention — your questions
- What is a backflow preventer and why does my house need one?
- A backflow preventer is a valve that lets water flow only one way — into your irrigation system or building — so fertilizer, lawn chemicals, or stagnant line water can never siphon backward into the drinking water supply. Any home with in-ground sprinklers has one, usually a brass assembly on a pipe near the sprinkler valves.
- Why did I get a letter from JEA about backflow testing?
- The letter means your property has a registered backflow assembly and its annual test is due — routine, not a sign anything is wrong. First Coast utilities confirm each year that these devices still hold. Send us a photo of the letter and we take it from there, test included, report filed for you.
- How often does a backflow preventer need to be tested in Jacksonville?
- Once a year for most assemblies — the standard across JEA, Clay County Utility Authority, and St. Johns County service areas for irrigation and commercial connections. The internal checks wear with time and water quality, so an annual pass confirms the device still seals. We can put yours on a yearly cycle.
- What happens if I ignore the backflow test notice?
- The utility follows up, and continued non-compliance can eventually mean water service is interrupted until a passing test is on file. It rarely gets that far, and it never needs to — the test is a modest, single-visit item.
- How much does backflow testing cost?
- The test itself is one of plumbing's smaller line items; the final price depends on the assembly type and size, how accessible it is, and whether repairs are needed. A failed test obligates you to nothing — you get a free estimate and an upfront quote first, and the utility paperwork is included either way.
