Backflow Repair
Failed the test? Rebuilt check valves, relief valves and seats, then retested and refiled so you are back in compliance on one visit where possible.
Quick answer
A failed backflow test almost always means worn internals, not a dead device: check discs, springs, seats, or the relief valve on an RPZ. Those are rebuild-kit repairs done in place. After the repair the device is retested and the passing report is filed with your utility.

What you get.
Every time.
The price is quoted before the visit. The person who quotes it is the person who shows up, and the certification number on the paperwork is his. If it is not the right service for you, you hear that on the phone.

- 3Straight answer when replacement makes more sense
Most backflow preventers fail the same way. Debris gets past the strainer and fouls a check seat, a spring loses tension, a rubber disc hardens, or the relief valve on a reduced pressure assembly stops opening at the right differential. None of those needs a new device. They need the right rebuild kit and someone who knows the assembly.
Repair is where we differ from a test-only outfit. A lot of testers in Seminole County are on the utility list for testing and nothing else — Longwood's own program is explicit that the city tests and does not repair. That leaves you with a failed report and a deadline. We carry parts for the common assemblies and fix what we can on the same visit, then retest and file the pass.
When we tell you to replace instead: a body that is cracked or corroded through, a device that has been rebuilt more than once and keeps failing, or an assembly type your utility no longer accepts for that application. Replacing a backflow preventer is plumbing work in Florida and needs a licensed plumbing contractor. We will tell you that plainly rather than sell you a repair that buys you six months.
Timeline: a same-visit repair is the goal when we already have the kit on the truck. If a part has to be ordered, you get the date, and we handle the retest and the filing when it is in.

Backflow Repair — FAQ
Can a failed backflow preventer be repaired, or does it have to be replaced?
Repaired, most of the time. Worn checks, seats, springs and relief valves are all rebuild-kit parts. Replacement is for cracked or corroded bodies, devices that keep failing after a rebuild, or an assembly type your utility no longer accepts for that use.
Is the retest included after a repair?
Yes. A repair without a passing test on file has not fixed your problem with the utility. Retesting and refiling the report is part of the repair.
Do you replace backflow preventers?
No. In Florida, installing or replacing a backflow assembly is plumbing contractor work. We repair and test. If your device needs replacing we tell you, and once a plumber has installed the new one we test it and file the initial report.
How soon can you repair a failed device?
If we tested it, the same visit is the goal whenever the kit is on the truck. If someone else tested it and you have a failed report and a deadline, call with the make and model off the device so the right kit comes out on the first trip.
Holding a notice? Call the tester.
Read us the notice. We tell you who it says should do the test, what it costs if that is us, and — if your city already tests for you — that you do not need us at all.
