A failed assembly rarely needs much. We shut off the water, open up the checks or relief valve, clean or replace what's worn, reassemble and retest. Most of the time it's done in one visit.

Starting from the numbers
Every assembly repair starts with the test readings. They tell the tester which part of the device isn't doing its job, whether it's the first check, the second check, the relief valve or the air inlet.
That matters because it keeps the repair focused. Instead of replacing everything, we go straight to the part that failed and look for the cause: debris on a seat, a cracked disc, a weak spring, a torn diaphragm.
If someone else tested the device and it failed, send us their readings. They're on the report, and they help us show up with the right parts so the repair can usually be done in one visit.
What happens during the repair
With the readings in hand and your approval on the price, we shut off the water to the device. Depending on the setup, that may mean the whole property or just one line, like irrigation or the fire service.
We open the failed section, remove the internal parts and clean the seats. Worn rubber, springs or diaphragms are replaced with the manufacturer's parts. The body is checked for cracks and the shutoff valves for leaks.
Then the assembly goes back together and the water comes back on. Most repairs take 30 minutes to an hour of water downtime. On a busy business, we can often schedule around your hours.
Retest and filing
A repair isn't finished until the device passes again. Right after reassembly, we run the full test, the same procedure used on the annual test. If everything holds, the result is recorded as a pass after repair, along with the parts replaced.
We file that report with your water district so your device shows as compliant. You get a copy by email.
If the retest still shows a problem, we keep working until it passes or tell you why it won't. Sometimes a device that's had several repairs, or one with damage to the body, is better off replaced. We'll give you the numbers so you can decide.
Repair or replace
In most cases, repair is the better deal. Parts cost a fraction of a new device, and a good rebuild holds up well.
Replacement wins when the body is cracked, parts are discontinued, the device keeps failing year after year, or it's no longer the right type for how the water is used. Districts sometimes require an upgrade after a change of use, like a double check becoming an RP.
You'll get our honest take and, when it's a close call, prices for both options so you can choose.
Preventing repeat failures
If debris keeps fouling the same device, there may be a reason upstream. Recent water main work, old galvanized pipe or construction nearby can all send grit down the line.
In some cases, a strainer ahead of the device helps, though not every district allows them and they need cleaning. We'll tell you if we think something upstream is causing repeat failures and what your options are.
Working around your hours
Shutting off water at a restaurant at noon or a clinic during appointments isn't an option. For businesses, we schedule repairs around your hours, early mornings, late afternoons or slower days.
Let us know when water can be off and for how long. We'll plan the repair to fit, and the retest and filing happen before we leave.
Repair pricing explained
Pricing depends on the size of the assembly, which part failed and which parts it needs. A small home device kit costs far less than rebuilding a large fire line assembly.
The quote you approve covers parts, labor, the retest and the district filing. If a new device would cost roughly the same, we'll mention it so you can choose.
Managers can have us send the quote directly to the owner or board. Once it's approved, we do the repair, file the passing report and email a copy to everyone who needs one.
Water shutoff
Usually 30 to 60 minutes for a standard repair. We'll tell you before we start.
Questions
What if parts aren't on the truck?
We order them and come back. Most parts arrive within a few days.
Can you repair it if someone else tested it?
Yes. Send us the failed readings and we'll quote the repair.
Will the report show it failed first?
Yes. Districts expect the report to show the initial result and the passing retest after repair.
Do you quote before starting?
Always. You approve the price before we open the assembly.
Can you repair it the same day as the test?
Often, yes, if we have the parts on the truck. Otherwise we order them and come back.
How long does an assembly repair take?
Most are done in one to two hours, including the retest.
What to expect when you book backflow assembly repair
Booking takes a couple of minutes by phone or online. We confirm the address, the device and how to reach it, and we'll give you a time window that works for you. For most homes, you don't need to be there.
On the visit, a certified tester does the work with a calibrated gauge and explains anything that comes up in plain terms. If a repair is needed, you'll get the price before anything happens. When the device passes, we send the report to your water district and email you a copy. Our office is open seven days a week, 6am to 12pm, and emergency calls are answered around the clock.
